摘要
综合运用瓦斯地质、数理统计及矿井瓦斯防治等相关理论和方法,研究了大宁煤矿的瓦斯地质规律,分析了井田地质构造特征对煤层瓦斯赋存的影响,结果表明,煤层埋深是控制煤层瓦斯赋存的主要因素。并依据煤层瓦斯含量与煤层埋深的线性回归关系预测了大宁煤矿煤层瓦斯含量的变化趋势。在此基础上,提出了针对大宁煤矿的优化矿井通风方式,采用立体交叉瓦斯抽采措施及建立煤与瓦斯突出预警系统的瓦斯综合防治措施。
By utilizing several factors including gas geology, mathematical statistics, gas control measures together with related theories and methods, the application of gas geology law in Daning Coal Mine was studied and the influence of structure characteristics on gas occurrence in the coal seam was analyzed. The results showed that the geological structure was the major factor in controlling gas occurrence. The trend of gas content in the coal seam was predicted based on the linear regression in relation of gas content and buried depth of the coal seam. According to this result there were several practical applications in the Daning Coal Mine. These in- clude： Improving the mine ventilation system, Utilisating the three-dimensional cross gas extraction measures and, Establishing coal and gas outburst early-warning system.
