平煤十矿戊_(11)煤层探放老空水技术研究

Research on Gob Water-Controlling Technology of Wu_(11) Coal Seam in 10th Coal Mine of Pingdingshan Coal Industry Group

平煤十矿在开采戊11煤层过程中,采空区积水给安全生产带来水患威胁,采掘工作面普遍存在涌、突水问题。通过分析研究矿井水文地质条件,介绍了该矿在探放采空区积水中采取的措施,为采掘工作面的安全生产提供了技术指导。

In the mining process in Wull Coal Seam of the lOth Coal Mine,the gob water brought to the safety threat of flooding. The problems of gushing （suoden） water generally existed at the mining face. By analyzing the hydrogeological conditions of the mine, the measures taken in the mine water exploration gob are introduced. The technical guidance is provided for safety in production at the mining face.
