摘要
为探究陕西西韩兴隆煤矿有限公司突出煤层区域预测瓦斯含量临界值,按照矿井始突瓦斯压力及《防治煤与瓦斯突出细则》提供的区域预测瓦斯压力参考临界值0.74 MPa计算了煤层瓦斯含量理论临界值,现场考察了原始瓦斯含量,分析了突出危险的关联性,初步确定了瓦斯含量临界值,最后对确定的区域预测瓦斯含量临界值进行了扩大验证,从而最终确定兴隆煤矿二水平3#煤层区域预测瓦斯含量临界值为6.0 m^(3)/t合理有效。
In order to explore the critical value of predicted gas content in the outburst coal seam area of Shanxi Xihanxinglong Coal Mine Co.,Ltd.,based on the initial outburst gas pressure of the mine and the areas provided in the"Detailed Rules for Prevention and Control of Coal and Gas Outburst",the article predicts a gas pressure reference critical value of 0.74 MPa,calculates the theoretical critical value of the coal seam's gas content,conducts on-site inspections of the original gas content,analyzes the correlation between the outburst danger,and preliminarily determines the critical value of gas content,and after verification,it finally determines that the reasonable and effective critical value for predicting gas content of Level 2 in No.3 coal seam area of Xinglong Coal Mine is 6.0 m^(3)/t,which has certain reference significance for predicting outburst coal seam areas.
