腾晖煤业2号煤层老窑巷道积水疏放技术研究

Study on water drainage technology in No.2 coal kiln roadway of Tenghui Coal Industry

腾晖煤业三采区范围内的采空区及废弃小煤窑的积水严重影响了矿井的安全生产。以三采区10号煤主运输巷、运输大巷、材料大巷掘进区域为研究对象,采用瞬变电磁法进行物探,探测结果显示距离10号煤主运输巷200~300 m范围内存在采空区,水害危险性不确定;使用定向长钻孔技术进行钻探验证,确定主要含水区域距离10号煤主运输巷约280 m;探测结果为巷道安全掘进奠定了基础,已经施工的定向长钻孔作为排放水孔。

In the empty mining area,the waste small coal kiln,the waste coal mining area and the waste small coal kiln,the water will seriously affect the safety production of the mine.Using No.10 coal transportation lane,transportation lane and material lane,the test results shows the mining area within 200~300 m.The test results of about 280 m;from 10 have established the directional long drilling as the discharge water hole.
