摘要 根据辛置煤矿地质和水文地质资料,对矿井下组煤充水条件进行了深入研究分析,得出辛置矿井充水条件延伸水平越深,水文地质条件类型越复杂,开采难度也越大。矿井充水水源主要是下石盒子组K8砂岩含水层、太原组K2灰岩含水层、奥陶系灰岩含水层以及采空区积水,矿井主要导水通道为断层、陷落柱、采动导水裂隙带和封闭不良的钻孔,这些导水通道会对煤矿的安全生产造成极大的影响,需要采用井下探放水、注浆堵水、留设保护煤岩柱、保障排水能力等措施来加以防治。 Based on the geological and hydrogeological data of Xinzhi coal mine,makes an in-depth study and analysis of the water-filling conditions to the underground coal seam mining, and concludes that the deeper the water-filling conditions of Xinzhi coal mine extend,the more complex the hydrogeological conditions,and the more difficult the coal mining. The mine water source is mainly K8 sandstone aquifer of Xiashihezi formation,K2 limestone aquifer of Taiyuan formation,Ordovician limestone aquifer and goaf water,the main mine water underground watercourse are fault,collapse column,water flowing fractured zone and not properly sealed bore holes. These underground watercourses will have great influence on the safety of coal mine production. Water hazard prevention measures will be taken such as water resources probing and discharging with undergound borehole,grouting for stopping up water,coal and rock pillar protection and enhancing drainage capacity.
