摘要
以淮北杨庄煤矿Ⅱ617综采工作面特大突水事故为研究背景,通过对其突水地段地质与水文地质情况、突水水源与导水通道、底板防隔水性能、不同应力场相互作用的研究,认为淮北杨庄矿Ⅱ617综采工作面特大底板突水灾害的发生,是其岩性场、应力场与渗流场耦合作用的结果.最后,提出了杨庄矿在回采过程中应采取的防治水安全技术保障措施.
Based on the extreme disaster of water-inrush through the floor strata in the fully mechanized coal face Ⅱ617 in Yangzhuang mine, Huaibei coal basin, the study was carried out on the mine geological and hydro-geological conditions in the water-inrush area, the resource of water-inrush and passageway of water-transmit, the waterproof capabilities of the floor strata and the combined effect of different stress fields. The results showed the water-inrush hazard in floor strata is the coupled result of lithology, stress and seepage in Ⅱ617mining panel in Yangzhuang mine, Huaibei coal basin. At last, safety measures of groundwater hazards prevention were put forward for mining above confined aquifer.
