端氏煤矿综采工作面顺槽沿空留巷技术的应用

Gob-side Entry Retaining Filling Technology for Fully-mechanized Working Face in Duanshi Mine

沿空留巷技术是无煤柱开采技术的一大发展方向,它是维护在工作面后方的采空区边缘巷道。端氏煤矿在综采工作面回采过程中,通过有效的巷旁支护和巷内支护技术,将本工作面的回采巷道保留下来,作为邻近工作面的一条回采巷道使用,收到了好的效果。

Gob-side entry retaining is one of major developing directions for mining technology without coal pillars, which can maintain the marginal roadways of mined-out areas in the back of working face. In the process of fully-mechanized caving in Duanshi Mine, effective roadside support and roadway support could retain the caving entry of the working face in order to be used for the adjacent working face, which has achieved the ideal effect.
