阳泉荫营煤矿棚户区二期采空区注浆处治实例

On examples of grouting treatment at goaf of second phase of shanty towns at Yinying coal mine of Yangquan city

以荫营煤矿矿区西南部某拟建场区为例,介绍了其工程概况,并阐述了采空区注浆孔设计、浆液参数设计及材料的选择,从钻孔施工工序、注浆工序施工、浆液配制、注浆施工四方面,分析了注浆施工方法,并进行了质量检验,结果显示其强度符合设计要求。

Taking some planned constructed area in the southwest of Yinying coal mine as the example,the paper introduces its engineering survey,illustrates the selection for the grouting hole design at goaf,serosity parameter design,and materials for the goaf,analyzes the grouting construction methods from the drilling construction sequence,grouting sequence construction,serosity preparation,and grouting construction,and undertakes the quality inspection,so it proves that the strength adheres to the design requirement.
