通过优化开拓巷道的设计，即提前开采巷道上方保护煤柱，促使开拓大巷布置在工作面回采后的采空区应力降低区内，以使巷道提前减压，从而降低巷道的变形破坏。巷道减压开采方式提高了矿井煤炭回收率、减少巷道维护量、矿井经济效益得到增加。
通過優化開拓巷道的設計，即提前開採巷道上方保護煤柱，促使開拓大巷佈置在工作麵迴採後的採空區應力降低區內，以使巷道提前減壓，從而降低巷道的變形破壞。巷道減壓開採方式提高瞭礦井煤炭迴收率、減少巷道維護量、礦井經濟效益得到增加。

Through optimizing the design of pioneering roadway,that is,to exploit the proG tective coal pillar above the roadway in advance to lay the pioneering roadway in the stress reducG ing zone in afterGmining gob to release pressure in roadway ahead of time,the roadway deforma- tion and failure are reduced.Using the roadway decompression mining method makes the coal re- covery rate improve,the roadway maintenance decrease,and the coal mine economic benefits in- crease.
