摘　　要：针对济宁二号煤矿四采区边角煤块段受断层构造及水患等复杂地质条件影响的实际情况,提出2个边角煤工作面布置优化方案。综合考虑矿井实际技术装备水平、两方案施工难度、经济性对比,最终选定方案二,可提高煤炭回采量,解决矿井采掘接续紧张局面。According to the actual situation of the corner coal block in the fourth mining area of Jining No.2 Coal Mine,which is affected by complex geological conditions such as fault structure and flood,two optimization schemes for the layout of corner coal working faces are proposed.In comprehensive consideration of the actual technical equipment level of the mine,the construction difficulty and economic comparison of the two schemes,the second scheme is finally selected,which can improve the coal recovery and solve the tense situation of mining and excavation.
