腾晖矿为了解决矿井瓦斯超限的难题，本文以腾晖矿 2202 工作面为工程背景，采用灰色关联法对腾晖矿影响瓦斯覆存的因素进行分析，发现覆岩的厚度对瓦斯覆存影响最大；同时利用数值模拟软件对岩层瓦斯压力进行研究，瓦斯压力沿着钻孔中心轴向外呈现增大的趋势，模拟瓦斯压力最大值为 0.52MPa，最后对腾晖矿进行瓦斯防突研究，通过钻孔抽采有效控制了矿井的瓦斯含量，降低了矿井瓦斯压力，保证矿井的安全生产。“,”in order to solve the problem of gas overrun in Tenghui mine, this paper takes the 2202 working face of Tenghui mine as the engineering background, and uses the gray correlation method to analyze the factors affecting gas overburden in Tenghui mine, and finds that the thickness of overburden has the greatest impact on gas overburden；At the same time, the numerical simulation software is used to study the gas pressure of the strata. The gas pressure increases outward along the central axis of the borehole, and the maximum value of the simulated gas pressure is 0.52MPa. Finally, the gas outburst prevention research is carried out in Tenghui mine. Through the borehole drainage, the gas content of the mine is effectively controlled, the gas pressure of the mine is reduced, and the safety production of the mine is ensured.
