近距离突出煤层群瓦斯综合治理技术研究

摘要

Under the condition of short distance outburst coal seams group ,carrying on the effective regional gas control measures ,including the necessary gas extraction and coal seam outburst elimination , can ensure safety in the process of mining .In response to the problems of the district gas control of short distance outburst coal seams group in Yuanxiang coal mine ,based on the target coal seams gas storage and transportation analysis ,the paper puts forward the suitable for Yuanxiang coal mine continuous mining district gas outburst control measures ,Optimizes the original coal seam gas extract parameters and the protected coal seams in pressure relief gas extraction parameters ,and forms the Yuanxiang coal mine district comprehensive gas control technology .The usage of the technique can effectively reduce the gas content of outburst coal seams , eliminate the outburst risk of outburst coal seams , ensure the effectiveness and continuous of coal mining ,and provide the technical guarantee for the safety and high quality of mining operations .%近距离突出煤层群条件下，进行有效的区域瓦斯治理措施，包括必要的瓦斯抽采和煤层消突措施，能够保障开采过程中的安全。本文针对原相矿近距离突出煤层群区域瓦斯治理中存在的问题，分析目标煤层瓦斯赋存及运移规律，提出适合原相矿采掘抽衔接的区域防突措施，优化原始煤层瓦斯预抽参数和被保护煤层卸压瓦斯抽采参数，最终形成原相煤矿区域瓦斯综合治理技术。该技术的使用有效的降低了突出煤层的瓦斯含量，消除了突出煤层的突出危险性，缓解了原相煤矿采掘抽接替紧张的矛盾，为矿井的安全高效开采提供了技术保障。
