rock filling

On the premise of the stability of roof and top coal, the displacement regularity of surrounding rock must be rationally used to determine the reasonable filling pattern and filling strength in order to ensure the filling stability and a good result of retaining roadway.

当采用综放沿空留巷时，在保证顶煤及顶板稳定前提下，合理利用围岩移动规律，确定合理充填方式和充填体强度，就能保证充填体稳定，达到很好的留巷效果。
