矸石充填加高水材料注浆开采方式的实践应用研究

Study on Practical Application of Grouting Mining Method of Gangue Filling and High Water Material

为有效处理沙曲一号煤矿掘进施工中产生的矸石,在理论计算的基础上进行了矸石充填加高水材料注浆的应用研究。观测结果表明:煤矿地面最大下沉量38 mm,最大倾斜值为0.88 mm/m,下沉速度为0.78 mm/d,地面下沉量对建筑物无破坏影响。

In order to effectively deal with the gangue produced in the excavation construction of Shaqu No.1 Coal Mine,the application study of gangue filling and high water material grouting is carried out on the basis of theoretical calculation.The observation results show that the maximum subsidence of the coal mine ground is 38 mm,the maximum inclination is 0.88 mm/m,the subsidence speed is 0.78 mm/d,and the ground subsidence has no destructive effect on the building.
