摘 要:针对峰峰集团大淑村矿部分村庄下压煤较多、资源浪费的问题,该矿调整172404工作面开采方案,将原规则长条形条带布置,优化为不规则的刀把形条带布置,由原来的采宽70 m,变为里段采宽125 m,外段采宽70 m。结果表明,该方案在建筑物变形允许的范围内最大限度的提高资源的回采率,解放呆滞煤量约20万t,增加效益约4000万元。In response to the problem of resources waste due to more coal under building in some villages in Dashucun Mine of Fengfeng Group,the mine adjusted the mining plan of 172404 working surface by optimizing the original long strip arrangement into an irregular knife-shaped strip,from the original 70 m mining width to 125 m in the inner section and 70 m mining width in the outer section,the results showed that the plan maximized the recovery rate of resources within the allowed range of building deformation,liberating about 200,000 tons of stagnant coal,increasing the benefit of about 40 million yuan.
