新疆汉水泉矿区侏罗系地层地面预注浆技术探讨

摘要

Jurassic strata characteristics of Hanshuiquan No�3 Mine were introduced, based on analysis of the formation conditions, rock conditions, fracture conditions and containing water conditions. According to the analysis results, the groutability of Hanshuiquan mine was initially identified. Ground pre-grouting design was carried out according to the formation characteristics; and the feasibility of surface pre-grouting technology in the mining area of the Hanshuiquan was verified according to the construction situation and grouting parameters.%介绍了汉水泉三号矿井侏罗系地层特点，对地层条件、岩石条件、裂隙条件及含水层条件进行了分析。根据分析结果，初步确定了汉水泉矿区侏罗系的可注性；同时，结合地层特点进行了井筒地面预注浆设计，并根据实际注浆施工情况和参数，论证了地面预注浆技术在汉水泉矿区侏罗系地层的可行性。
