摘要
介绍了高低负压瓦斯抽放系统在老屋基矿的应用效果。应用该系统解决了单套系统既要保证区域性预抽 ,同时又要满足采空区抽放的矛盾 ,大大提高了矿井瓦斯抽放率和回采工作面的瓦斯抽放率 ,确保了矿井的安全生产。
The application effectiveness of both high and low negative pressure systems in Laowuji Mine is described. The application of the systems can meet the need for both regional gas predrainage and the gas drainage from mined area, thus greatly raising the gas drainage rate in the mine and coal faces and guaranteeing the safe production in the mine.
