大采高综采工作面两巷掘进时基本都是沿煤层底板掘进,在回采过程中两巷顶煤无法回收,垮落后全部遗留到采空区,既浪费资源,又会留下安全隐患,文章提出了回收综采工作面两巷顶煤的设想,具有一定的参考意义。 During the tunneling of coal seams, the two sides of the fully mechanized coal mining face are basically driven along the coal seam floor. During the mining process, the top coal of the two sides can not be recovered and all of the leftovers go to the goaf, which will waste resources and cause potential safety hazard. The article puts forward the idea of ​​recovering the top coal in two roadways of fully mechanized mining face, which has a certain reference value.
