摘要
煤层瓦斯参数是矿井瓦斯防治的基础数据,内蒙古宁发一矿属于技术改造矿井,以往煤层瓦斯参数测定数据极少,日常瓦斯管理工作缺乏技术依据。简述了宁发一矿煤层瓦斯参数的测定方法和过程,测定矿井主要煤层瓦斯压力、瓦斯含量、煤层透气性系数等参数,丰富了矿井瓦斯基础数据体系。评价主要煤层瓦斯可抽性,预测煤层瓦斯分布规律,为矿井瓦斯赋存规律研究和瓦斯防治提供了技术支撑。
Coal seam gas parameters are the base dates of gas prevention and control.NingFa No.1 coal mine is in the technical reconstruction,there are little coal seam gas parameters,so technical foundation be lacking in routine gas management.Describe in Ningfa No.1 coal mine measuring method and process of gas parameters,measure gas pressure,gas content,coal seam permeability coefficient and so on,in order to increase the gas datas.Assess drainage difficulty degree of main coal seams,forecast the gas distribution law,in order to offer the technology support to studying gas occurrence and controlling gas in coal mine.
