摘要
介绍了平煤集团煤矸石的物质组成,分析了其环境效应影响,并对其治理从理论上做了综合分析,结合其综合治理现状,提出了煤矸石的井下直接分选回填技术在平煤集团煤矸石山综合治理中的现实意义,并介绍了国外该回填技术的两种常用方法.
Coal gangue is waste and residue remaining during the mining and processing of coal. It is also the largest solid industrial residue in annual production and dump amounts in China. The article introduces the physical makeup of coal gangue at Pingdingshan Coal Mine Group, analyzes the influence of environment effect, and studies the control measures comprehensiveiy in theory. The operation significance of the direct-sorting back-packing technology under the shaft during the comprehensive control of coal gangue at Pingdingshan Coal Mine Group is then pointed out.
