摘　　要：桐木沟矿区285中段102电、103电两采场所在区域地质条件复杂,在采用有底柱分段崩落法传统的采切、支护、中深孔及采场大爆破工程设计方案进行采矿时,暴露出消耗砼料较多、部分工程塌方严重、大爆破效果差、回采率低等诸多弊病。因此,在与102电、103电两采场地质条件基本相同的104电、105电两采场的各项工程设计方案作了较大的改进。改进后采场作业的安全性改善,大爆破效果及回采率提高,取得了良好的效果。The geological conditions in the area where the 102 and 103 power mining sites are located in the 285 middle section of Tong-mugou mining area are complex.When using the traditional mining cutting,support,medium deep hole,and large blasting engineering design scheme with bottom pillar segmented collapse method for mining,many drawbacks such as high consumption of concrete materials,severe collapse of some projects,poor effectiveness of large blasting,and low recovery rate are exposed.Therefore,significant improvements have been made to the engineering design schemes of the 104 and 105 power mining sites,which have similar geological conditions as the 102 and 103 power mining sites.After improvement,the safety of mining operations has been enhanced,and the effectiveness of large-scale blasting and recovery rate have been im-proved,achieving good results.
