| Abstract: | Basic on the character of projection of low-penetrative coal bed in Guizhou province,combining with the method of drawing out gas,the features of arranging exploring-laneway and reversing mine technology of ZhongLing Mine,applying the existing technical means,the paper point out the idea to draw out the gas above and below the mine at the same time,namely increasing the rate of utilization of the gas.Then certain economic benefits can be obtained by using the gas comprehensively.What'more,it also can reduce... |
