摘　　要：根据瓦斯涌出特点和规律,对上隅角瓦斯浓度低、涌出量大的问题,采用大流量、低负压瓦斯抽采系统抽采瓦斯,以减少瓦斯涌向采掘空间;对高位孔(位于冒落带上部)、本煤层预抽钻孔、穿层卸压钻孔等瓦斯浓度高、储量大的问题,采用大流量、高负压瓦斯抽采系统抽采瓦斯,以降低煤层瓦斯压力和含量,实现分源、分系统、不同负压的多泵、多管路抽采瓦斯。实践表明,分源控制抽采治理瓦斯技术的实施,消除了煤层煤与瓦斯突出危险性,有效降低了回采期间瓦斯超限次数。Based on feature and law of gas emission, as well as low concentration and large volume problem of upper coner gas, gas extraction system with mass flow and low negative pressure was adopted to reduce gas mining space. According to high gas concentration and big storage of high hole（ upside caving zone）, drainage drilling of this coal seam, unloading drill wear layer and so forth, pump and pipeline extraction gas of split source, different subsystem, negative pressure were achieved. Furthermore, seam gas pressure and content were decreased with this effective system. The practice showed that dangerness of coal and gas outburst was eliminated and gas transfinite times during mining period were reduced through implement of gas control technology by sub-source control.
