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。 Very soft coal seam in South China occupies a large proportion of coal, it is difficult to mine, at present mainly artificial exploitation. This kind of coal seam has the difficulty of controlling the coal wall and difficult to seal the gangue in Laotang. A kind of supporting equipment and coal mining method adapting to the occurrence conditions of this kind of coal seam is designed and studied to realize the mechanization of mining and ensure Coal mining safety, reliability and high yield and efficiency.
