摘要
针对"瓦斯抽采率"和"瓦斯抽放率"在定义上所存在的不足等问题,从实际使用情况出发,认为目前的"瓦斯抽采率"或"瓦斯抽放率"实际上是瓦斯抽出量与风排瓦斯量之间的比例关系,定义为"瓦斯抽排率"更为合适。提出了采用"瓦斯抽出率"取代"瓦斯抽采率"或"瓦斯抽放率"来衡量瓦斯抽出情况更为合适,并给出了相应的瓦斯抽出率定义及计算方法。
According to the deficiencies on definition of gas extraction rate and gas drainage rate,from the practical application it was considered that current gas extraction rate or gas drainage rate is the ratio of gas drainage volume and ventilation air methane volume.It is preferable to be defined as gas pumping rate.The suggestion is put forward on replacement of gas extraction rate or gas drainage rate by gas pumping rate to measure the drainage quantity.And it is provided that corresponding definition of gas drainage efficiency and calculation method.
