五阳煤矿集中胶带大巷巷道支护技术研究

Study on Wuyang Mine Concentrated Belt Roadway Support Technology

五阳煤矿集中胶带大巷所处区域采空区裂隙带、断层较多且巷道穿过奥灰含水层,地质条件复杂,通过对围岩性质和围岩强度进行分析,对该胶带大巷过裂隙区域的支护参数进行了优化设计,得出了详细的支护优化方案。现场监测巷道变形量结果表明,集中胶带大巷过裂隙支护技术完全能够保证矿井的安全高效生产。

Wuyang Mine concentrated belt main roadway locates in goaf fracture zone, with multiple fault, complicated geological conditions and roadway through ordovician limestone aquifer, through the analysis of the nature and intensity of surrounding rock, support parameter of the main roadway crossing fracture zone was designed, the optimized support scheme was got. The roadway deformation quantity according to the field monitoring results, concentrated belt main roadway crossing fracture support technology could ensure the safe and efficient production of mine.
