"Mining is the main activity that supports civilization. Actual mining presents contradictory concept to the health of the planet. Its business model is linear, fragmented and characterized by inefficiencies in the utilization of water, energy and mineral resources which generate waste and pollution. Before mining begins, it is critical to determine the vulnerability of the ecosystem and after mining, it is critical to determine the depletion of nature. Attending to these vital matters will require quantifying and measuring them. The purpose of this study is to provide and establish the metric to assess the performance and manage a sustainable future for our existence and that of our planet. This index is defined to measure and control Nature Friendly Sustainability (NFS) based on understanding nature. This index will determine the condition of nature constructed on the measurement of physical, chemical and biological equilibrium. Proposing a new mindset for mining design to satisfy nature’s needs would be to offer the same opportunities to future generations. Hence, sustainability is synonymous with equilibrium under a limited ecosystem. Nature is interconnected. Finally, this index of NFS is readable, standardized and relevant to keep nature’s needs in equilibrium. Establishing and NFS index is the next metric for humanity. INTRODUCTION There are a multitude of definitions of what sustainability is. Most of them are defined in terms of the corporate entity from which they emanate. The classical definition of management states that, “if we do not measure it, we cannot manage it.” Management of ecosystems is the definition of sustainability. Indicators of quantity and quality of sustainability are vital in order to create a metric for sustainability. These indicators will measure the depletion and degradation of nature as they occur through human intervention. The first step is to create a metric of sustainability to simplify its definition. The definition of sustainability is based on whether or not you consider nature to be finite or infinite, which is described in Nature Friendly Sustainability (NFS) [1]. The definition of NFS applies to any anthropogenic activity with an understanding of the equivalent activity in nature. That is to say, human activity with nature requires balance and equilibrium in order to be sustainable. The importance of this equilibrium is quantified in a set of metrics in order to establish measurement and acknowledge indicators for our dependence on nature. Sustainability is synonymous with equilibrium in any ecosystem that is limited and fragile. In the graph is the explanation of sustainability definition. See Graph 1"

IN 1949 the Government Printing Office issued Bureau of Mines Bulletin 468 3 and previously (in 1948) Bulletin 467 4 as part of the program under the Synthetic Liquid Fuels Act of April 5, 1944 (30 U. S. C., 321-325, and amendments). The two bulletins, relating to oil shale and its products, were published to present abstracts of all patents in this field from 1845 to 1945 5 or before the Synthetic Liquid Fuels Act was passed. Also, as part of this program, bulletins were published on patents relating to the pressure hydrogenation of coal e and the Fischer-Tropsch synthesis.7 The Synthetic Liquid Fuels Act was not extended beyond April 1955, but it inspired much increased activity in the field of oil-shale research, and many patent applications were filed. It is the purpose of this bulletin to abstract the patents issued in the United States, the United Kingdom, and Europe from 1946 to 1956, inclusive. A few older patents omitted in the previous bulletins have been included.

THE Synthetic Liquid Fuels Act. (30 U.S.C., 321-325, and amendments) became law April 5, 1944, and a period of intensive research and development in this field was begun by the Bureau of Mines. As part of this program, bulletins were published on pressure hydrogenation.3 the Fischer-Tropsch synthesis,4 anal oil shale.5 The Bureau also has published a short bibliography on coal gasification,6 mostly of a theoretical nature. Because coal gasification is prerequisite to either the Fischer-Tropsch or coal-hydrogenation processes, publishing this sizable collection of technical information in this form will be valuable. The material will be presented in three parts, as follows: I. United States Patents. II. United Kingdom Patents. III. Other Foreign Patents. The domestic patents for this bulletin were collected between 1953 and 1955.

THE Synthetic Liquid Fuels Act (30 U.S.C., 321-325, and amendments) became law April 5, 1944, and a period of intensive research and development in this field was begun by the Federal Bureau of Mines. As part of this program, bulletins were published on pressure hydrogenation,3 the Fischer-Tropsch synthesis,4 and nil stifle.5 The. Bureau also has published a short bibliography on coal gasification,6 mostly of a theoretical nature. Because anal gasification is prerequisite to either the Fischer-Tropsch or coal-hydrogenation processes, publishing this sizable collection of technical information in this form Will Ire valuable. The material will he presented in three parts. as follows I. United Stares Patents. II. United Kingdom, Australian, Canadian, and South African Patents. III. Other Foreign Patents. Part I appeared in early 1960. Part II follows.

Belgium, French, German, Italian, and Swedish Patents. The domestic patents for this bulletin were collected between 1963 and 1955. Some of the Foreign Patents were collected at the same time and a few of them later in 1961. Part I was published in 1960; Part II was published in 1962.
