摘　　要：煤巷留顶煤施工,顶部煤体的控制是施工中主要难点,同时也是事故的频发点,如何在施工过程中减少事故发生,提高施工安全性,加快施工效率等。通过根据煤层软硬情况及现场实际施工情况,在不同条件下施工不同的超前支护,结合现场解决问题。通过此方法本工作面在抬顶煤掘进期间,效果较好。Coal Roadway of coal roof construction, control of top coal is the main difficulty in construction, but also the accidents occur frequently, how to reduce the construction in the construction process, proposed the construction safety, speed up the construction efficiency etc..According to the soft and hard condition of the coal seam and the actual construction situation in the field, different advanced support is constructed under different conditions, and the problem is solved on the spot. By this method, the face is better during the top coal tunneling.
