The helium resources base of the United States was estimated by the U.S. Bureau of Mines (Bureau) to be 894.6 Bcf as of January 1, 1989. These resources are divided into four categories in decreasing degree of assurance of their existence: (1) helium in storage and in proved natural gas reserves, 282.4 Bcf, (2) helium in probable natural gas resources, estimated at 237.7 Bcf, (3) helium in possible natural gas resources, estimated at 263.1 Bcf and (4) helium in speculative natural gas resources, estimated at 111.4 Bef. These helium resources are further divided into depleting and nondepleting, with the helium in storage being in a classification. The depleting resources are those associated with natural gasfields that are, or will be produced for the natural gas they contain. Almost all of the helium in potential (probable, possible and speculative) natural gas resources is included in this classification. These depleting resources are estimated to contain 775 Bcf of the total helium resource base. Helium resources contained in nondepleting natural gas resources, i.e., those in shut-in, abandoned, or otherwise nonproducing natural gas fields, are estimated to total 84 Bcf There is 35 Bcf of helium in storage in the Federal Government-owned Cliffside Gasfield near Amarillo, TX.

The oil fields of Arkansas, all situated in the southern part of the State, have played an important part in the development of petroleum production in the northern coastal plain region of the Mid-Continent area. From the first discovery of oil in southwest Ouachita County in 1920 to December 31, 1930, a total of 480,167,5604/ barrels of crude petroleum has been produced from' this region. Development of the Arkansas fields proceeded rapidly after 1920. The El Dorado field was discovered in Union County in 1921. Drilling in Ouachita County resulted in the discovery of the Smackover field in 1922 and subsequently in the development of the whole southern area. To November 31, 1939,459 / producing wells had been drilled in 25 fields, aggregating 53,7356 acres of proved territory in 6 counties. Peak annual production for the State was reached in 1925, when 80,823,7007/ barrels was produced, resulting largely from flush production from the Smakover field, which rose td an average of 444,9507 barrel daily during that year. During 1924, 1925, and 1926 Arkansas ranked fourth among the oil-producing

"INTRODUCTION The first important discovery of petroleum in New Mexico was near Dayton, Eddy County, where the Brown well was drilled in 1909, and small quantities of oil were produced. In 1911 and 1912 wells were drilled in McKinley County, but commercial production did not begin until the discovery of the Hogback field, San Juan County, in 1922. The discovery well in the Artesia field, Eddy County, drilled in 1923, gave impetus to active drilling in many areas. Since 1924 New Mexico has produced petroleum in commercial quantities and since 1930 the State has joined the ranks of the big produc¬ing States, being sixth or seventh in total production in recent years.Production by years. 1924 to 1940, inclusive, taken from annual figures in Bureau of Mines Minerals Yearbook, are given in table 1. The total production shown is 274,331,000 barrels. Andreas 3/ has published production figures for the year 1940 and a resume of all production to the end of 1940. Data from his report are presented in table 2 for each field sampled. The cumulative production, as given by Andreas, is 270,618,575 barrels."

In Fayette County, the Pittsburgh bed has been the major source of production for almost two centuries. Although historical documentation is not available, there is evidence, that the Pittsburgh bed may have been discovered in Fayette County near Mt. Braddock, Pa., as early as 1753. The earliest known reference to coal in western Pennsylvania was recorded in 1758 by a Quaker trader, James .Kenny, who reported having seen coal in Fayette County. The production of coke from Pittsburgh coal was begun in 1841, when two 10-foot beehive ovens were erected in the Connellsville region to make coke .for shipment by river to the market. The Connellsville, region extends from Latrobe, Pa., in Westmoreland County to South of Uniontown, in Fayette County. Connellsville coke was used with great success in the Clinton furnace in 1859.

The value of Alabama's nonfuel mineral production in 1980 was $328.6 million, a decrease of $7.8 million from 1979. Cement, crushed stone, lime, clays, and sand and gravel continued as the major commodities produced. Alabama led the Nation in the production of crushed marble; was second in bauxite; third in native asphalt, ferroalloys, kaolin, and oyster shell; fourth in dimension marble, masonry cement, and bentonite; and fifth in fire clay and lime. Alabama ranked in the top 20 States in total value of non-metallic minerals produced. Adverse economic conditions in the construction and metals industries impacted on the minerals industry in Alabama. Mineral producers supplying raw or finished materials to these industries experienced periodic reductions in sales during the year. Unit price increases did not keep up with inflation.

In 1990, the aggregate value of world international export trade in mineral commodities was estimated at more than $64 billion in current (1990) dollars, about 8.4% higher than that in 1989, but still 8.7% below the record high set in 1980. Table 8 provides a data series for the estimated value of world export trade in all mineral commodities from 1979 through 1990, as well as a breakdown of this total into fuel and nonfuel commodities. It is noteworthy that for this 1990 edition, trade data for the year of review were available in time for inclusion, whereas in previous editions, the latest available global trade data were for the year prior to the year of review. Hence, as regards trade, this edition of Minerals in the World Economy updates the 1989 edition by 2 years rather than by only 1. For this reason, it is appropriate to note that the 1989 global total value for inter-national export trade in mineral commodities was almost $596 billion, 11.1 % above the revised 1988 level of more than $536 billion, both figures expressed in current dollars for the appropriate year. Despite the considerable increase in the dollar value of mineral commodity exports, their share of total export merchandise trade declined to 19.1 % in 1990 from 19.7% in 1989. At 19.1%, this share was very near the recent year record low of 19.0% reached in 1988. The year 1990 was the fourth in a row in which the total value of world mineral commodity export trade increased.

Between 1989 and 1991, the greatest number of accidents in surface coal and metal/nonmetal mines involved haulage trucks. In 1995, the most frequently cited factor contributing to the 100 fatalities in these mines was powered haulage. In 1996, over 50% of the 84 Fatalities in mining that year were in surface mining. Because some of the world's largest mobile equipment is used in surface mines, and this equipment is involved in so many accidents and fatalities, new technologies are needed to alert truck drivers and people in spaces around the truck to the possibilities of collisions.

From November 1943 to April 1944, the Bureau of Mines put down 18 churn-drill holes aggregating 2,571 feet of bore in an investigation of the virtually abandoned zinc deposits of the north-central Arkansas district, principally in Marion, Boone, Searcy, and Newton Counties. The ore of this area occurs in flat-lying sedimentaries of the Mississippian and Ordovician ages. Much of the zinc is in the form of carbonate and silicate, although some sulfide has been produced. Preliminary studies resulted in selection for investigation of the Big Hurricane mine in northwest Searcy County, the Spies mine in northeast Newton County, and the Coon Hollow mine in eastern Boone County The comparatively large production of th.ese properties in the past was a factor in the selection. This report describes the work accomplished in the investigation and presents the data obtained.

RECORD production of crude petroleum, lime, crushed marble, and talc highlighted the mineral industry of Alabama in 1963. Among the States, Alabama ranked second in the production of bauxite, third in the production of scrap mica and native asphalt, and fifth in iron ore. The mineral industry of Alabama was dominated by mining and processing coal and stone, the manufacture of cement, and the production of crude petroleum, which together comprised 86 percent of the total value of production, compared with 82 percent in 1962. The iron-ore industry continued to decline; in 1959 the value of iron ore produced was 12 percent of the total State production value; in 1960, 11 percent; in 1961, 10 percent; in 1962t 8 percent; and in 1963, 5 percent.

In broadest overview, UN global industrial production indicators released and shown in table 2 suggest that the extractive sector of the world's mineral industry in aggregate registered a very slight upturn in 1991 relative to its 1990 performance. It also shows a continued rebound in the industry from the recessionary period of the mid-to late-1980's. These same indicators as calculated in late 1991, however, reflected a very minor downturn in extractive mineral industry operations between 1989 and 1990. This latter downturn represented a notable revision from the data reported in the immediate previous edition of this chapter, which suggested a tiny upturn. The apparent slight 1991 upturn in extractive sector industrial output generally was not mirrored in the performance of the processing sectors of the global mineral industry. Although the aggregate index for the chemicals, petroleum, coal, and rubber products manufacturers (see table 3) showed a notable gain in 1991, similar indices for nonmetallic mineral products and for base metals registered declines between 1990 and 1991. Examination of regional performance indices shows that the difficulties experienced in 1990 in maintaining output levels within the countries that formerly constituted the CMEA were reinforced by trends toward reduced gains in output levels, if not actual reductions in output, in several other areas. Generally speaking, the traditional developed market economy countries recorded downswings in overall industrial activity in 1991, particularly after midyear, whereas developing market economy countries logged gains. The developed market economy country downturns, however, were not nearly as significant as were the downturns recorded for the former centrally planned economy states - those that before 1992 were either constituent Republics within the U.S.S.R. or the latter's CMEA partners.

The U.S. economy was considerably stronger in 1976 than in 1974 or 1975. Real gross national product (GNP) rose sharply in the first quarter of 1976 and then increased at a more moderate rate for the remainder of the year. The unemployment rate fell until June and then increased for moat of the remainder of the year, finishing at the same rate as it had started the year. The inflation rate continued to decline in 1976. Reasons for the relatively low rate (compared with those of 1974 and 1975) included small increases in food prices and only moderate increases in energy prices. Total U.S. output measured in terms of GNP increased 11.6% in 1976. Real GNP in 1972 constant dollars rose 6.2%. Inflation as measured by the implicit price deflator increased 5.1%. In real terms, gross private domestic investment for residential structures rose 22.7% in 1976 after declining 14.7%a in 1975; State and local Government expenditures increased 1.4% in 1976; and personal consumption expenditures for services rose 4.5%. The Federal Reserve Board (FRB) index of industrial production increased 10.2%.

MOST OF THE key items in the bituminous-coal and Lignite industry declined in 1954 compared with 1953. Production, consumption, exports, average value per ton, men working, and days worked all declined; however, in the field of mechanization, the percentages mechanically loaded, mechanically cleaned, mined by auger, and mined by stripping all increased, as did production per men per day. Production.-The output of soft coal in 1954-391.7 million tons- was 14 percent less than the 457.3 million tons produced in 1953. The lower production in 1954 was due largely to a sharp reduction in consumption in the United States and to a drop in exports.

THE year 1950 was one of increased activity in almost all branches of the abrasives industry, with nearly all abrasive materials showing a marked increase in tonnage and value. New records were made In the production of tripoli, ground sand and sandstone, pumice and pumicite, and garnet. Total production of crude artificial abrasives in the United States and Canada increased 17 percent in tonnage and 30 percent in value. Imports of industrial diamonds increased 100 percent in total value and 72 percent by weight, the 1950 importation being the largest since 1944. Imports of corundum increased 76 percent in tonnage and 4 percent in value.

Carbon monoxide poisoning is one of the most widely distributed and most frequent causes of industrial accidents . Carbon monoxide gas is a product of incomplete combustion , and since it is without color , odor , or taste , its presence is frequently unsuspected in many places where it exists . It is an ever present danger about blast and coke furnaces , smelters , and foundries . It may be found in buildings having a leaky furnace or chimney , and in buildings where a gas stove is used without a proper flue connection , such as is often found in tenements , tailor shops , and boarding houses . Hospitals receive annually a great number of victims of poisoning , either by accident or in an attempt at suicide , from artificial illuminating gas . People may be affected by leaks wherever water gas is formed or used . The exhaust gases from gasoline motors under average running conditions usually contain 5 to 7 per cent carbon monoxide , and sometimes as much as 13 per cent ; deaths from running an automobile engine in a closed garage are not infrequent . A similar danger may arise in operating gasoline engines in launches without sufficient ventilation . The gas is formed also in stoker rooms , in gun turrets on battleships , in petroleum refineries , and by the Lablanc soda process in cement and brick plants . In underground mines carbon monoxide may appear as the result of shot firing , mine explosions , or mine fires , and in tunnels where automobiles , coal or oil - burning locomotives are operated . In spite of the common occurrence of carbon monoxide poisoning there appears to be no uniformly recognized treatment for a person overcome by carbon monoxide . In the rescue work of the United States Bureau of Mines , however , a method has been developed which has been supported by laboratory investigation , and has proved successful in practical experience , over a period of years . As outlined in this article , the method is useful in the hands of first -aid men as well as physicians .

"INTRODUCTION Toxic oxides of nitrogen 5/ are formed or liberated in many industrial process and may constitute a definite hazard to the health of persons exposed to the atmospheres thus produced. Oxides of nitrogen occur in the gases involved in the use of explosives, in the gasoline products of welding operations in the exhaust of internal-combustion engines, in the vicinity of electrical discharges, in the combustion of nitrated materials, and in chemical process involving nitration or the use of nitric acid, Itis evident that oxides of nitrogen may constitute an occupational hazard in many industries, and therefore it is important that those concerned with the control of such hazards be equipped with a technique suitable for the determinations of oxides of nitrogen in the concentrations of,hygienic significance."

Although motor gasoline marketed in the United States in January of this year was, on the average, slightly more volatile than that sold in January 1925, the improvement in quality is too small to be of importance. In other words, there is no evidence that any radical change in the quality of gasoline is being made at the present time. During the past six years the Bureau of Mines has made semi-annual surveys of the gasoline marketed in the United States, the survey just completed being the thirteenth in the series. The cities in which samples have been collected have been chosen as representative of the more important marketing territories as it is obviously impracticable to obtain a sample of every gasoline sold in the entire country.

The value of abrasive materials consumed in the United States increased 37% in value over that of 1983 to $439 million; of which, 58% was manufactured abrasives, 36% was industrial diamond (natural and synthetic), and 6% was natural abrasives. Production value of natural abrasives, which consist of crude tripoli, special silica stone, garnet, and emery, increased 4% Production of crude tripoli, a finely disintegrated chert, increased 12% in quantity and 8% in value. Shipments of processed tripoli increased only 3% in quantity but increased 16% in value, with large increases occurring in both major end-use categories. Production of garnet, an abundant iron-aluminum silicate, decreased slightly in quantity and value after posting continued increases in quantity and value since 1980. There was a significant decrease in the quantity and [ ]

The value of Alabama's nonfuel mineral production in 1981 was $312.7 million, a decrease of $15.7 million from that of 1980. Output of most non fuel minerals declined; cement, crushed stone, lime, clays, and sand and gravel were the major commodities produced in the State. Alabama led the Nation in the production of crushed marble; was second in bauxite; third in native asphalt, kaolin, and oyster shell; fourth in bentonite, dimension marble, and fire clay; fifth in masonry cement; and sixth in common clay, ferroalloys, and lime.
