强含水层暗斜井掘进工作面预注浆方法

Pre-injection method of the driving face of a subinclined shaft with strong water-bearing bed

通过葛店矿暗斜井工程施工实例,介绍了强含水层掘进工作面预注浆工程与施工情况.注浆后工作面涌水量满足了掘进技术要求,在经济、安全、施工速度等方面都显示出较大的优越性,具有推广的价值.

By taking subinclined shaft construction in Gedian Coal Mine as an example,this paper introduces the pre-injection project and construction of the driving face with strong water-bearing bed. After pre-injection,the water from the driving face can satisfy all kinds of technical requirements,which displays superiority in economy,security and construction.
