新庄煤矿瓦斯地质单元划分与瓦斯防治

Division of gas geological unit and gas prevention and control in Xinzhuang Coal Mine

统计了新庄煤矿近年来瓦斯涌出量及煤层瓦斯含量基本情况,分析得出影响该矿井瓦斯含量变化的主要因素有开采标高、断层、褶曲、上覆岩层厚度等方面。在此基础上,结合矿井开采实际划分了矿井瓦斯地质单元,根据不同地质单元内瓦斯赋存情况,制定了有针对性的瓦斯治理措施,从而做到有的放矢地治理瓦斯,避免瓦斯超限和瓦斯事故的发生。

The basic situation of gas emission and coal seam gas content in Xinzhuang Coal Mine in recent years was counted,and the analysis showed that the main factors affecting the change of gas content in the mine are mining elevation,fault,fold,overburden thickness,and so on.On this basis,combining the reality of mine mining division of the mine gas geological unit,according to the different geological units inside gas occurrence condition,the targeted gas control measures were formulated so as to control the gas with a definite aim,and to avoid the occurrence of gas overrun and gas accidents.
