沁城井田主斜井工作面深孔预注浆技术

Deep-hole Pre-injecting Technique on the Working Face of the Main Inclined Shaft of Qincheng Coalmine

根据沁城井田主斜井过基岩含水层地质概况,比选了注浆堵水方案治理井筒涌水的方法,最后确定了预注浆施工技术方案。介绍了预注浆方案的设计及施工方法,并分析了注浆效果。

According to the geological siluation of the bedrock water-bearing layer of the main inclined shaft of Qincheng Coalmine, people made the comparison and selection of treating scheme for the shaft water pouring by using various injecting and ponding schemes, and determined the pre - injecting construction technique at last. This paper introduces the design of the pre - injecting scheme and the construction method, and analyzes on the injecting results.
