煤矿采空区因其容易引发地表沉陷,致使建筑物发生沉降,而且会引发地表下沉、倾斜、水平变形等,是一种影响较大的地质灾害。引用山西省万家寨引黄入晋工程北干线1#隧洞出口段煤矿采空区治理工程I标为实例,介绍了该工程的工程概况、采空区概况和地质概况,阐述了具体的水泥粉煤灰浆液注浆法工艺流程,浅析了水泥粉煤灰浆液注浆法在煤矿采空区治理工程中的应用,以期为类似煤矿采空区治理工程提供良好的借鉴。
Because of its easy to cause surface subsidence, the mined-out area of coal mines cause the buildings to settle, and will cause surface subsidence, inclination and horizontal deformation, which is a kind of geological disaster with great influence. Reference Shanxi Wanjiazhai Yellow River diversion project into the North Route 1 # tunnel exit section of coal mined-out area I project as an example, introduced the project overview of the project, gob of general situation and geological overview, elaborated concrete cement The application of cement fly ash slurry grouting method in the goaf control project of coal mine is analyzed in order to provide a good reference for the similar goaf control project in coal mines.
