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 basic data of mine gas prevention and control. Inner Mongolia Ningfa Mine belongs to technological transformation mine. There is little data of gas parameters in past coal seams, and lack of technical basis for daily gas management. The method and process of measuring gas parameters of coal seam in Ningfa No.1 coal mine are briefly described. Parameters such as gas pressure, gas content and gas permeability coefficient of main coal seam are measured, and the gas foundation data system of mine is enriched. Evaluating the gas pumping ability of the main coal seams and predicting the gas distribution rules of the coal seams provide the technical support for the research on gas occurrence laws and gas prevention and control in coal mines.
