辛置煤矿南区2#煤层瓦斯治理技术优化研究

Research on Optimization of Gas Control Technology for 2#Coal Seam in Southern Area of Xinzhi Coal Mine

做好煤矿瓦斯预防及治理工作,对于保障煤矿的安全开采具有重要意义。辛置煤矿南区2#煤层在工作面接替过程中瓦斯涌出量显著降低,需要对现有的瓦斯治理方案进行优化来降低经济成本。简要分析了瓦斯抽放泵站停运的安全性和经济性,并探讨了重新启动瓦斯抽放泵站的条件,以期更好地为煤矿安全生产服务。

Doing a good job in the prevention and control of coal mine gas is of great significance for ensuring the safe mining of coal mines.The gas emission of the 2#coal seam in the south area of Xinzhi Coal Mine was significantly reduced during the face replacement process,and the existing gas control plan needed to be optimized to reduce economic costs.This paper briefly analy-zed the safety and economy of shutting down the gas drainage pumping station,and discussed the conditions for restarting the gas drainage pumping station,in order to better serve the safe production of the coal mine.
