fully-mechanized coal face%cross-roadway%high water-content material%filling%artificial bottom
A new method using high water-content material to mechanically fill cross-roadways to form artificial bottom for coal faces was introduced. The reasonable determination of filling range, the optimization of the compounding ratio of high water-content material, and the filling technique were discussed in detail. This new method has been spread after industrial testing in Baodian Colliery. Compared with the traditional method, the manual wooden chock method, the new one decreases about 40% of the filling range and cost in dealing every one set of cross-roadway in the testing condition.
