低瓦斯矿井瓦斯涌出与瓦斯煤尘爆炸危险性的探讨

On the Danger of Gas Emission and Gas and Coal Dust Explosion in Ningdong Low Gas Mine

通过瓦斯的赋存状态及影响煤层瓦斯含量的因素分析,确定宁东矿井属于低瓦斯矿井。由于宁东所处的大地构造环境,矿井地质构造发育,产生局部瓦斯富集,矿井开拓引起温度和压力的变化,易诱发瓦斯突出。监测瓦斯,确保安全生产。

Based on the analysis of gas occurrence state and factors influencing gas content in coal seams, the paper confirms that Ningdong mine is a low gas mine. Owing to the tectonic environment, the development of geological structure causes partial gas gathering while the development of mine causes changes in temperature and pressure, which can easily induce gas outburst. Gas monitoring and coal dust control should be done to ensure safety in production.
