针对燕子山矿井下瓦斯含量对安全生产的威胁，解决瓦斯安全防治问题，分析了煤层瓦斯赋存特征和条件，建立了地质构造对煤层瓦斯影响分析模型，分别对井田构造、采区构造、煤质、顶板基岩厚度和煤层埋藏深度对瓦斯赋存影响进行分析，并提出了瓦斯安全防治技术方法，防治效果表明，距离工作面较远处瓦斯含量可降到30%以下，距离工作面较近处瓦斯含量可降到10%，在浓度较高处通过高效抽采可有效控制瓦斯含量。

In view of the threat of gas content to safety production in Yanzishan mine, the characteristics and conditions of coal seam gas occurrence are analyzed, and the influence analysis model of geological structure on coal seam gas is established. The influence of mine field structure, mining area structure, coal quality, roof bedrock thickness and coal seam burial depth on gas occurrence is analyzed, and the technical method of gas safety prevention and control is put forward. The control effect shows that the gas content can be reduced to less than 30 % far from the working face, and the gas content can be reduced to 10 % near the working face. The gas content can be effectively controlled by efficient extraction at high concentration.
