【摘要】 针对淮南矿区A组1413A工作面在开采过程中受到厚层砂岩直覆、底板灰岩含水层威胁的问题,根据实际地质条件,采取顶板砂岩水探放、底板灰岩水疏放、边界断层防水煤柱注浆加固、支架升阻、深孔预裂爆破强制切顶等措施,并对矿井水文自动监测系统和工作面微震监测系统实现实时监测、监控,实现了安全高效生产。更多还原

【Abstract】 Based on straight covering thick sandstone and threatening of floor limestone aquifer in mining process of A group 1413 A working face in Huainan Mine Area,measures of exploring roof and floor sandstone water,grouting reinforcement of boundary fault waterproof pillar,lift and drag of holder,and deep hole pre- splitting blasting cut top were adopted on the basis of actual geological conditions.At the same time,real time monitoring of microseismic monitoring and analyzing system along with mine hydrology automatic monitoring system was implemented,which realized safety and high effective product.更多还原
