Selective Placement of Strip Mine Overburden in the United States. I. Contract Report

摘要

The selective placement of coal strip mine overburden is examined. Physical and chemical properties of spoil detrimental to revegetation and ground water are detailed. Five mining methods already used in the industry, that are capable of selectively handling waste, are examined. Technical and economic comparisons are made for the systems when applied to realistic mine settings. The same analysis is conducted for five novel methods capable of selectively handling waste. Comparisons are made between novel and existing methods. Suggestions for new and modified equipment are outlined and recommendations for further research are provided.
