摘要
煤层瓦斯赋存状态是研究矿井瓦斯涌出规律和瓦斯灾害防治的技术基础。某矿5煤层局部瓦斯异常涌出,已经开始对煤矿的安全生产有所影响和制约。于此,笔者采用统计分析和分源计算两种方法,对采掘工作面瓦斯涌出量进行了预测,分析了采掘工作面瓦斯涌出影响因素和涌出来源,得出了煤层瓦斯压力、煤层瓦斯含量、煤层透气性系数、煤层残余瓦斯含量、钻孔瓦斯涌出量等参数,随采深增加而变化的规律,并提出了针对性的防治措施。
The gas occurrence rule is the techno-basement of the study on the gas emission rule and gas harm harness. The part gas uneven emission in mou mine had effect on the mine＇s plan yield. To solve the gas uneven emission, the gas occurrence in work face was forecasted by means of statistical analysis and dif- ferent-source calculation, and the effect factors and sources of gas emission are analyzed. The relation between gas pressure and elevation, the relation between gas content and elevation, the relation between hole gas emission and elevation were obtained, finally the aimed preventive measures are brought forward.
