预注浆在井巷过地质异常带中的应用

The Application of Pre-grouting in Coal Roadway through the Geological Anomalous Body

针对地质异常体岩体破碎、不完整、巷道支护困难等问题,对预注浆技术从注浆方案、注浆材料、注浆机具、注浆施工工艺、施工组织管理、质量控制等方面进行了简要阐述,并以顾北矿南翼胶带机巷过地质异常带为例,介绍预注浆加固的成功经验,为类似条件的施工提供了参考。

In terms of the rock crush and imperfection in geological anomalous body and the difficulties in roadways＇ support,the grouting plan,grouting materials,grouting equipments,grouting construction technology,construction organization and management and quality control in pre-grouting technology are discussed,and taking the belt conveyor roadway in the south wing of Gubei Mine through the geological anomalous body for example,the successful experience is introduced,which will provide references for the similar constructions.
