帷幕注浆技术在煤矿水害防治中的应用

Application of curtaingrouting technology inpreventionandcontrol ofwater disaster incoal mine

在分析矿井水文地质条件和与邻近的库车河水力联系的基础上,确定了帷幕注浆封堵矿井与库车河间导水通道的治水方案。施工过程中,采用布置双排钻孔、下设多级套管、分段循环注浆、填注新型高分子注浆材料等技术手段。施工结果表明:帷幕注浆参数设计合理,帷幕墙具有较好的抗渗性能,可以满足矿井治水和安全开采的要求。

Based on the analysis of the hydrogeological conditions of the mine and the relationship between the mine and the adjacent Kuqa River,the water control scheme of curtain grouting blocking the water diversion channel between the mine and the Kuqa River is determined.In the process of construction,technical means such as double row drilling,multi-level casing,staged circulation grouting and filling of new polymer grouting materials are adopted.The construction results show that the curtain grouting parameters design is reasonable and the curtain wall has good impermeability,which can meet the requirements of mine water control and safe mining.
