随着煤矿机械化水平的提高,原有的通风方式和通风方法已不能解决高产高效工作面瓦斯涌出量的问题,确保其高产高效必须结合矿井的地质开采条件,实施矿井瓦斯抽放。
With the improvement of mechanization of coal mines, the existing ventilation methods and ventilation methods can not solve the problem of gas emission from high productivity and high efficiency workfaces. To ensure high productivity and high efficiency, the mine gas drainage must be implemented in combination with the geological mining conditions of mines.
