摘要
针对顾桥煤矿南区进风井井筒新生界松散层厚,注浆深度深、质量要求高、工期紧等特点,采用直孔与S型钻孔相结合的注浆施工技术,取得了良好的效果。着重介绍了注浆技术方案、施工工艺、注浆效果及经验、体会等。
Due to the thick loose level of the downcast shaft Cenozoic group, the large depth of grouting, the requirement of high quality, the time limit for the project in the construction of the Southern Field of Guqiao Coal Mine, the straight hole and the S drilling hole were tied in wedlock each other to carry out the grouting technology, and got fine effects. This paper focuses the grouting scheme, the construction technology, grouting effects and some experience.
