摘要
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。
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.
