摘要
基于陕西230个煤矿的统计数据,对这些煤矿的数据进行深入的分析,总结回采率影响因素,进而从煤矿生产规模、地质构造复杂程度、开采方法、煤层赋存条件等影响因素对回采率进行统计分析。得出各因素对陕西煤矿回采率的影响状况,为提高矿井回采率提供一定基础。
Mining Recovery is studied in - depth based on 230 coal mines＇investigation data of Shaanxi province, and influencing tac- tors are summarized. In addition, factors on the coal recovery include scale of coal mine, geological structure condition, coal - mining method and conditions of coal seam occurrence are analyzed in Shaanxi province, and the influence degree of these factors on recovery are carried out. The research provides a basis to improve recovery.
