“Old Borate,” located in the Calico Mountains east of Barstow, California, lead domestic colemanite production from 1884 through 1907. Mineral exploration at “Old Borate” in the early 1980's, examined borate mineralization in Tertiary lacustrine strata. Surface sample and drill hole locations, geology and structure, were hand-drafted on paper maps. To re-evaluate this data, the information was digitized using Geographic Information Systems software. Digital Elevation Model based terrain modeling integrated surficial samples with drill hole data to locate favorable drilling targets. Structural relationships were used to identify hypothetical resources formed by the leaching of boron from surface exposures, redeposited at depth.

The application of Geographic Information System (GIS) technology to support the planning, design and analysis of coal mines is discussed. Traditional two-dimensional GIS structures are modified to produce a three- dimensional GIS system that combines the efficient topologic description of a cubic grid cell skeletal structure with the precision surface representation of a Triangulated Irregular Network (TIN). The surface terrain and any subsurface strata, such as a coal seam, are represented by separate TIN'S. Any attribute data to be assigned to the TIN'S are stored in polygon overlays. Any remaining spatial data are stored as link strings or nodes in a global data set. The most valuable application of the system is the production of map products. Both projections and cross-sections of surface or subsurface structures are possible, in either horizontal or vertical planes. Engineering data, including lengths, areas, or volumes, can be calculated.

"Abstract Large scale In Situ Barrier Wall Construction projects, specifically those related to earth dams, dikes, and levees, frequently require stringent quality control measures to ensure the success of the wall. This presentation discusses the applications of Geographic Information Systems (GIS) technology to capture information from multiple data streams and provide geotechnical feedback, quality control, and project control feedback. Techniques used to geospatially analyze verticality data from secant piles and panels will be demonstrated. Examples will be presented from barrier wall installations at two sites owned by the U.S. Army Corps of Engineers (USACE): the Wolf Creek Dam in Kentucky, and Center Hill Dam in Tennessee.IntroductionDeep foundation installations require contractors to collect a substantial amount of information over the course of a project, both for internal quality control of construction progress and for demonstrating compliance with customer or owner specifications. Methods of collecting information are constantly improving, bringing with it the need for a systemic approach to managing the increasing amounts and types of data. Handling these diverse types of data presents challenges with both budget and schedule demands. This paper discusses some techniques for adding or increasing quality control in barrier wall constructions by consolidating, visualizing and analyzing data using relational database and Geographic Information Systems (GIS) technology, collectively referred to as Information Management System (IMS) development. The IMS concept is designed to facilitate the collection, transfer and processing of data and provide an easy way to remotely access and visualize construction progress.The remainder of this paper presents the needs and objectives of an IMS applied to quality control in barrier wall construction, the components and data flows involved, the capabilities and user interfaces of the systems and the benefits for the end users. Examples are presented throughout from case study projects including: a pile barrier wall applied in the rehabilitation at the Wolf Creek Dam in Kentucky (under contract to the Treviicos-Soletanche Joint Venture), and a secant pile barrier wall currently under construction in the rehabilitation of the Center Hill Dam in Tennessee (under contract to Bauer Foundations Corporation) (both owned by the Nashville District of the USACE)."

"For a high hazard USACE facility, the Center Hill Dam in Tennessee, several disparate streams of data were compiled into a single geospatial and relational enterprise data management system to store, analyze, visualize and distribute the data collected during installation of a deep cutoff wall. These data streams included historical drawings and pre-construction plans and grouting records; geological data from boreholes; attributes of barrier wall elements; element verticality data analyzed from multiple measurement methods; and concrete field and laboratory analytical data. A previously developed data management system developed by the authors, WallTracker, was extensively modified to also include manually collected and real-time measurements from several types of dam monitoring instruments. The system now uses enterprise database technologies with Geographical Information Systems capabilities to manage and relate these data streams into a common platform and allows access to the raw and interpreted data via web and desktop-based interactive tools, including interactive map and cross-sectional viewers and other graphical and tabular reporting tools. One of the primary benefits of this system is the neartransparent interaction that is possible with the Nashville District of USACE on the project. These techniques can now be effectively incorporated into systems that address the unique construction and data management tracking requirements for dams, dikes, and levees.IntroductionThe Center Hill Dam rehabilitation, as with other deep foundation installations, requires the contractor to collect a substantial amount of information over the course of the project, both for internal quality control of construction progress and methods, and for demonstrating compliance with owner specifications. This paper discusses techniques used at Center Hill Dam for consolidating, visualizing and analyzing construction and instrumentation data using relational database and Geographic Information Systems (GIS) technology, collectively referred to as an Information Management System (IMS).The remainder of this paper presents the needs and objectives of the IMS, the components and data flows involved, the capabilities and user interfaces of the systems, and the benefits for the end users."

As more and more computer software is written for geological mapping applications, the users of the software are discovering the problems of transferring data between the programs, maintaining correct data and integrating maps produced last week with those produced today. One way to deal with these situations is by using a geographic information system (GIs). Last September the USGS and National Academy of Science held a 5-day GIs symposium on integrating technology and geoscience applications (USGS, 1988). It was followed in October by GEOTECH '88 (Peters and Krajewski 1989) which had a session exclusively for GIs applications in the Geo-Sciences. Editorials in Geobyte (Leonard, 1986, 1988) suggested that geographic information systems will be the next major computer programs to be adopted by the mineral industries. As far- back is 1985, the Computer Oriented Geological Society (COGS) printed An Introduction to GIs in their newsletter (Katz, 1985). About 20 years ago, a revolutionary idea occurred in the world of business data processing. It was the idea that all related data be stored in a standard format, in a single place and that all related computer application programs would use the same data.

We often read and hear, especially in the United States, that we are running out of critical metals. These are vague forebodings of stagna- tion or winding down of our civilization. Our technological progress has been rapid in the last 50 years and is still advancing at an accelerated rate, and predictions of its long-term impact on consumption and production of metals are more hazardous than ever in the light of the great economic and political shifts that are bound to continue. There are many factors that will have a hardly predictable but profound effect on pro- duction and consumption of metals over a time span of, say, 25 years. Among such factors are recycling, substitution, availability of capital, direct involvement of governments in financing and production, and the capability of producing much lower grade ores at possibly much higher prices relative to costs in the event of scarcity. I must state at the outset that my discussion of this topic does not take into account the role that deep-sea nodules containing copper, nickel, cobalt, and manganese may play, because I don't believe production from these deposits will be of much significance within the 25 year span I will be discussing.

MINERAL production of the United States is valued at over five billion dollars a year at present and the industry employs close to a million workmen, yet such maps as are available that might indicate the geographical distribution of this industry show only the location of coal and oil fields and of other mineral deposits. No recent map is available that shows this distribution in a quantitative way. The purpose of the maps and graphs here presented is twofold: (1) to give the mining engineer a clear conception of the relative value and the pattern of distribution of minerals in the United States; (2) to test the so-called block-pile (or grouped pillar) system of statistical mapping, which makes this presentation possible. (I discussed this method of mapping in an article which appeared in Economic Geology in 1939, Vol. 15, p. 185-188.)
