摘要
为搞清山西大远煤业有限公司煤层瓦斯赋存情况,采用井下钻屑解吸法对煤层瓦斯含量进行测定。通过对煤层埋深与瓦斯含量参数回归,得出二者的线性关系。使用2号煤层最大埋深处的原煤瓦斯含量作为基本参数对矿井2号煤层开采时瓦斯涌出量进行预测,并采用瓦斯地质法分析了影响2号煤层瓦斯赋存规律的地质因素,为该矿矿井通风和瓦斯治理提供依据。
For finding out the geological conditions of Shanxi Dayuan Coal Industry Company, the gas content of coal seam is determined by using underground drillings analysis, Through linear regression for coal seam burial depth and raw coal gas content, the linear relation between them is obtained. Then tak ing the raw coal gas content in the maximum burial depth of second coal seam as fundamental parame ters, the gas emission quantity of second coal seam is forecasted. Meanwhile the geological factors for coal seam gas occurrence regularities of second coal seam are analyzed. Thus the evidence is provided for mine ventilation and gas control
