The proved reserves of this coal mine are 461.99 Mt and the minable reserves are 445.49 Mt, with a mine life of 66.56 a. The

7、normal mine inflow is 57.45 m3/h and the maximum mine inflow is 367 m3/h. The mine gas emission rate is 0.5 m3/t which belongs to low gas mine. Based on the geological condition of the mine, I bring forward vertical shaft development with two mining levels and the extension of blind inclined shaft,a
