在一个回采工作面准备出来后,如何正确地予计回采期间的瓦斯绝对涌出量与相对涌出量,对于生产管理、瓦斯管理、合理供风等均有重要的现实意义。目前沿用的予计方法是根据历年来瓦斯递增值求算出瓦斯予计数值。这种方法对缺乏历史资料的矿井和新井就无法办到。有的老矿井虽有大量瓦斯资
After a working face is prepared, how to correctly predict the absolute emission and the relative emission of gas during the recovery period has important practical significance for production management, gas management and reasonable supply of wind. The current method used is to calculate the gas to the count value based on the incremental value of gas over the years. This method can not be done for mines and new wells that lack historical data. Although some old mines have a lot of gas capital
