矿井中的风流是井下瓦斯向外涌出的载体,它的物理特性参数发生变化,将会影响井下所有瓦斯涌出来源的游离态瓦斯向风流的运动,从而影响矿井的瓦斯涌出量.所谓大气物理特性参数,是指大气的气压,温度,湿度,重率,密度等等.这里在实测数据的基础上,就正常生产条件下测得的地面大气物理特性参数变化对矿井回风流瓦斯浓度变化的影响作一些分析和探讨.
Mine air flow is underground gas gushing out of the carrier, its physical parameters change, will affect the underground gas from all sources of gas flowing from the free-flowing gas to the wind, thus affecting the mine gas emission. The so-called atmospheric Physical parameters, refers to the atmosphere pressure, temperature, humidity, weight, density, etc. Here on the basis of the measured data, measured under normal production conditions of the physical characteristics of the surface of the atmospheric parameters of mine return air flow changes in gas concentration For some analysis and discussion.
