陈四楼矿太原组上段岩溶特征分析研究

Analysis and Study on Karst Characteristics of Upper Taiyuan Formation in Chensilou Mine

陈四楼煤矿二_(2)煤层底板灰岩岩溶承压水对矿井安全生产造成严重威胁。基于陈四楼煤矿开采现状及现有资料,围绕陈四楼煤矿太原组岩溶为研究对象,通过建立若干岩溶评价指标,结合矿水文地质特征,分析底板岩溶发育特征规律,为区内采掘设计、地质钻孔设计和煤层底板灰岩含水层改造提供参考依据。

Karst confined water in limestone floor of 二_(2) coal seam in Chensilou Coal Mine poses a serious threat to mine safety.Based on the mining status and existing data of Chensilou Coal Mine,around the Taiyuan Formation karst of Chensilou Coal Mine as the research object,through the establishment of a number of karst evaluation indexes,combined with the hydrogeological characteristics of the mine,the characteristics and laws of floor karst development are analyzed,which provides a reference for the mining design,geological drilling design and coal floor limestone aquifer transformation in the area.
