| 摘 要： | 瓦斯涌出量参数是衡量矿井安全状态的一个指标,也是新建矿井设计过程需要解决的一个重要课题.采用钻屑解吸指标法对西冯街煤矿3#煤层的原始瓦斯含量和残存瓦斯含量进行了测定并分析了瓦斯含量分布特征.利用线性回归方法研究获得3#煤层瓦斯含量与埋藏深度的关系,得出可燃质瓦斯含量增长梯度每100m为6.44m3/t.最后采用分源预测法对西冯街煤矿3#煤层上分层开采前期、中期和后期瓦斯涌出量进行了预测,并分析了矿井瓦斯涌出影响因素和涌出来源,对矿井通风与瓦斯抽采设计具有一定指导意义.

| Abstract: | As one index to measure the coal mine safety state, gas emission parameter is one important subject to solve for the new mine. The paper determinated the gas content of 3# coal seam with the help of desorption index of drill method and analyzed the gas content distribution of 3# coal seam. Then it got the relationship between gas content and buried depth of 3# coal seam and the gas content growth gradient was 6.44 m3/t for each 100 m. At last, the paper forcasted the gas emission of Xifengjie coalmine 3# co... |
