淮北煤田五沟煤矿第四系松散含水砂层注浆改造钻孔工艺研究
A study on grouting reworking drilling process in Quaternary loose water-bearing sand layer in Wugou the coalmine of the Huaibei coalfield
摘要
Abstract
In order to effectively curb the occurrence of mine water hazard and ensure the safe production of mines concerning both coal and water resources,focusing on the fourth aquifer of Section 1010 of the Wugou coalmine in the Huaibei coalfield,we put forward grouting reworking on the loose aquifer and gave an implementation plan.As a result,the grouting reworking can improve the safety of coal mining and the recovery of resources.The aquifer can be changed into water-proof layer by grouting,which completely eliminates the mine water risk and realizes the source control.The water-bearing property of the fourth aquifer was thus changed by grouting,and the thin bedrock structure became more stable even in coal mining.The practice proved safe and reliable,providing a reference for the safe production in the Wugou coalmine.关键词
