骆驼山煤矿岩溶裂隙水抽水试验

基于骆驼山煤矿透水事故发生后的水文地质补勘要求及具体水文地质条件,提出了岩溶裂隙水抽水试验的技术要求和方法,根据该技术要求和方法,分析了骆驼山煤矿岩溶裂隙水含水层的水动力条件。研究结果既提供了用数值法进行矿井涌水量计算所必需的技术资料,也对存在底板奥灰水威胁开采的煤矿特别是发生过陷落柱突水淹井的煤矿重新进行水文地质条件评价具有重要的参考价值。

Pumping Test on the Karstic Fissure Water in Luotuoshan Coal Mine

Based on the assignments of supplementary hydrogeological survey after water inrush accident happened in Luotuoshan coal mine,as well as its characteristics of hydrogeology,the new technical requests and working methods for the pumping test in Luotuoshan coal mine is proposed.According to the new technical requests and working methods,the hydrodynamic conditions of karstic fissure water in Luotuoshan coal mine are analyzed.The research results not only satisfy the request of numerical calculation for the mine discharge,but also provide important value for the reevaluation of hydrogeological conditions in those coal mines that mine under the threat of Ordovician limestone water and especially in which water inrush accident happened because of collapse column.
