摘　　要：针对赵家坝煤矿开切眼变形大、成型困难、支护难度大的现状,结合导硐爆破技术和分次支护技术,提出了一种新型实用的急倾斜"三软"薄煤层综采开切眼导硐施工技术。有效地解决了煤、矸运输问题,安全、可靠地完成了开切眼施工,对相似工程条件下的巷道施工具有借鉴意义。According to the present situation of large deformation, forming difficulty and difficult support in Zhaojiaba mine, the construction technology of a new type of coal seam is presented. Effeetively solve the coal and gangue transportation problem, safety, reliable completed the open cut construction, for similar engineering conditions of roadway construction is of great significance.
