The magic of technology brought by industrial revolution endowed human with power that they can do anything they want. It also turns natural resources into industrial energy and enhances the development of human society and civilization. Human uses direct comparison of input and output and the satisfaction degree of demands to measure the production activities, the economic benefit and management performance, regardless of the change of ecology that serves as the natural resources. However, since the ecological environment has been changing worse recently and natural disaster happened frequently human's dream of conquering the nature has been broken.展开更多

Here a region can be a country, a province, or a mining area, while a deposit is mainly related to a single type of mineral, although it can contain more than one types of minerals. In the past, to assess mineral resources was primarily to evaluate and forecast the total reserves of regional mineral resources. With the advancement of science, technology, and economy, the evaluation of mineral resources has developed from forecasting the reserves of them to comprehensively evaluating them on the basis of numerous factors.展开更多
