摘要
瓦斯抽放是防治煤矿瓦斯灾害事故的根本措施,长平矿经过几年的探索实践,逐步形成了煤层瓦斯抽放、地面钻井抽放及开掘底板岩巷穿层钻孔抽放等独具特色的立体式瓦斯抽放模式,多措并举,大大降低了煤层的瓦斯含量及矿井瓦斯涌出量,为进一步提高矿井瓦斯抽放率及瓦斯治理技术奠定了坚实基础.
Gas drainage is the fundamental measure to prevent and control the gas disaster accident. After years of exploration and practice, Chang-ping ore gradually formed the special stereometric formula about gas drainage, using the coal seam gas drainage, ground drilling and digging rock bottom to drain the seam gas. Taking various drainage measures greatly reduces the coal seam gas content and mine gas emission quantity, laid solid foundation to further improve the gas drainage and gas treatment technology standard.
