研究突出造成风流中的沼气。一次煤与沼气突出,在风流中形成了一个沼气流,它在相继断电的瓦斯测量仪的记录纸带上形成一个峰值:它先是直线上升,达到最大值后以近似于指数函数的形式下降。形成的沼气流,随着风流,经过井巷,直到地面。但有相当数量的沼气,却逆风扩散。研究目标。为了求出 CH_4气流进行过程 Research highlights the marsh gas in the Merry. Once coal and biogas stand out, a biogas stream is formed in the wind flow, which forms a peak on the recording tape of gas meters that are de-energized one after the other: first it rises linearly, reaches a maximum, and descends approximately in the form of an exponential function . The resulting biogas stream, along with the wind, passes through the shaft until it reaches the ground. However, there is a considerable amount of biogas, but the wind spread. Research objectives. In order to find CH_4 airflow process
