漳村煤矿西部扩区开拓设计方案探讨

为了延长漳村煤矿服务年限,设计将常村矿第二水平北六采区的资源作为漳村煤矿扩区进行开采,根据漳村煤矿井下及地面生产系统的现有情况,分析了影响漳村煤矿西部扩区开拓的主要因素,确定了新增的辅助工业场地布置在西部扩区的邑子村东北方向,同时在场地内新增副立井和西回风立井两个井筒,并从大巷布置、开采水平、采区划分等方面确定了漳村煤矿西部扩区的开拓方式,漳村煤矿西部扩区方案促进了矿井的科学、均衡生产,为煤矿可持续发展奠定了基础。

The mechanism and criterion of tectonic zone around karstic collapse column reactivation-induced water-conducting

In order to study the mechanism of tectonic zone around karstic collapse col-umn reacts to leak water and prevent water invasion in mine. According to the character of the surrounding cracks- penetrated water KCC, The fracture mechanics theory can be used to study the propagation and perforation process of cracks and hitches around the KCC. The criterion of crack start rupture and the length of secondary crack and criterion of crack propagation have been attained. The influencing factors of KCC reacts to water con-duction were analyzed.
