摘　　要：极软煤层在我国南方的煤层赋存中占有很大的比例,属于难以开采煤层,目前多以人工开采为主。该种煤层的开采存在着煤壁难以控制、老塘煤矸难以封挡等难点,设计研究了一种适应这种煤层赋存条件的支护设备和采煤方法,实现开采的机械化,保证了煤矿开采的安全、可靠和高产高效。Extreme soft seam covers a large proportion in occurrence of coal seam in the South of China,which is difficult to mine by machine, instead it is mined mostly by manpower. The difficulty mainly lies in control of coal face, block of gangue as well. In this paper, the author has designed and developed a kind of supporting equipment and mining method for this kind of seam, realized mechanized mining, and guaranteed mining safety, reliability and high efficiency.
