高瓦斯矿井瓦斯涌出量预测及抽采技术应用

Prediction of Gas Emission in High Gas Mines and Application of Extraction Technology

为有效提高瓦斯抽采效果,以晋普山矿瓦斯地质条件为背景,采用理论分析、现场试验方法对矿井瓦斯涌出量进行了预测,并对瓦斯抽采技术进行了优化应用。根据抽采效果,高位钻孔瓦斯抽采量平均为7.69 m^(3)/min,上隅角瓦斯浓度未出现超过0.5%,表明优化瓦斯抽采技术后,能够满足矿井日常生产需求。

In order to effectively improve the gas extraction effect,taking the gas geological conditions of Jinpu Mountain Mine as the background,theoretical analysis and on-site experimental methods were used to predict the gas emission rate of the mine,and the gas extraction technology was optimized and applied.According to the extraction effect,the average gas extraction volume of high-level drilling is 7.69 m^(3)/min,and the gas concentration in the upper corner does not exceed 0.5%,indicating that after optimizing the gas extraction technology,it can meet the daily production needs of the mine.
