A perfect introduction to sustainable mining for those new to the subject or those who require some revision, this book provides a basic overview of international sustainable mining practices since 1992, with particular emphasis upon practices in the Americas, Asia and Europe. The text begins by addressing issues such as the volume of waste generated by mining, mine closure planning and the environmental impacts, and then goes into specific detail in the following areas: cleaner production practices in Australia; blasting impacts and their control in the US; minimizing surface water impacts; minimizing groundwater impacts; use of environmental indicators in mining; and emerging mining technologies that minimize environmental impacts. The text contains relevant examples and case histories for ease of revision, and also includes a chapter on Best Mining Practices for Sustainable Mining and sub-chapters on small-scale mining, tailings pond management and hazardous waste management.

This report summarizes the results from the subsidence research study completed by the U.S. Bureau of Mines at the Roadside Mine, Powderhorn Coal Co., Palisade, Co. This research was conducted from February 1981 to August 1985, with additional data obtained during July 1991, to evaluate residual subsidence. The Bureau studied subsidence at three district room-and-pillar sections at separate locations over the mine and determined the maximum subsidence values and surface subsidence profiles for each mining section. Maximum subsidence of 3.0 ft occurred over the room-andpillar sections, with overburden depths ranging from 50 to 600 ft. Surface tension cracks had occurred, and were still evident during the residual subsidence survey.
