我国东部地区的透气性煤层低,仅仅依靠传统的风排瓦斯,已经不能适应当前的煤矿掘进生产需求,瓦斯抽放是当前一种瓦斯治理的有效方法。本文首先探讨了采空区瓦斯来源及瓦斯分布规律,提出了不同阶段的瓦斯抽放治理措施,最后对一通三防工作提出了一点建议。 Breathable coal seam in the eastern part of our country is low, relying solely on the traditional gas drainage, can no longer meet the needs of the current coal mine production, gas drainage is an effective gas treatment method. In this paper, the gas source and gas distribution in the goaf are discussed firstly, and the gas drainage control measures in different stages are put forward. Finally, some suggestions are put forward for the work of one-ventilation and three-prevention.
