摘　　要：本文重点探讨华阳集团二矿81104工作面回采期间过构造带技术方案;通过钻孔探测,确定该工作面构造影响范围为1000~1590 m,主要为褶曲构造;基于矿井实际条件,拟定三种过构造带方案;技术经济分析表明,方案一工作面推进用时83天,利润607万元,方案二工作面推进用时100天,利润-1014.08万元,方案三工作面推进用时76天,利润1572万元;显然,方案三为最佳方案。The paper focuses on the technology of crossing tectonic zone during stoping at 81104 working face in No.2 Colliery of Yangquan Coal Industry(Group)Co.,Ltd.,in which three schemes are presented through drilling exploration which determines the tectonic zone is folding with influence area of 1000 to 1590 m.Technical economy analysis show that Scheme 1 can make a profit of 6.07 million Yuan with working face advance time of 83 days;Scheme 2 can make a profit of minus 10.1408 million Yuan with working face advance time of 100 days and Scheme 3 can make a profit of minus 15.72 million Yuan with working face advance time of 76 days which is the optimal obviously.
