摘要
对贺西矿高瓦斯综采工作面煤层瓦斯基础参数测定过程,测定方法和计算方法进行阐述,并确定贺西矿3#煤层瓦斯压力、瓦斯含量、煤层透气性系数、钻孔瓦斯衰减系数等参数,这些基础数据是煤矿进行防治瓦斯和防突工作的重要依据。
For Hexi mine on High Gas Workface basic parameters of gas determination process,determination and calculation methods was described,and determine gas pressure,gas content,coal permeability coefficient,attenuation coefficient of gas drilling parameters of the Hexi Mine 3# coal seam,these basic data are important basis to coal gas and the outburst prevention work,but also for escorting safety production in Hexi coal mine.
