As perceived by the Bureau of Mines, the major current environmental problems relating to mining are lack of proper premining assessment and baseline data, subsidence during and after mining, destruction of surface contours, geometry and stratigraphy, creation and disposal of waste from mining and milling, disruption and contamination of the hydrologic regime, and unhealthy and damaging air pollution, noise, and vibrations. This paper describes the Bureau's program in projected research, development, and demonstration that are based on the probability of technology improvements to eliminate these problems.
