摘要
联合支护技术在"三软"煤层掘进施工中取得了良好的效果。巷道变形量小,实现了由被动支护向主动支护的转变,施工进度快,减轻了工人劳动强度,提高了矿井安全技术水平。
Combined support technology in the ＂soft＂ coal excavation construction has achieved good results.Small amount of roadway deformation achieved by the passive support to active support of the change,the construction progress faster,reducing labor intensity and improve mine safety technology.
