我们峰峰矿务局羊渠河矿,是一九五九年投产的超级瓦斯矿井,多井口生产,多水平提升。矿井总进风量为17613米~3/分,相对瓦斯涌出量为17.7～51.2米~3/吨/日,一九六六年开始进行瓦斯抽放工作,抽放瓦斯量为4～9米~3/分。几年来,在预防和处理瓦斯超限和积聚的斗争中,不断提高了通风瓦斯管理水平,杜绝了重大瓦斯事故,保证了矿井安全生产。我们的主要做法如下。 Our Fengquang Mine, Fengqu Mine, is a super-gas mine put into operation in 1959 with multi-well production and multi-level improvement. The total amount of air in the mine is 17613m ~ 3 / min, the relative gas emission is 17.7 ~ 51.2m ~ 3 / t / day, and the gas drainage work started in 1966. The gas drainage capacity is 4 ~ 9m ~ 3 / min. In the past few years, in the battle to prevent and deal with gas overrun and accumulation, the level of ventilation and gas management has been continuously raised, major gas accidents have been eliminated and mine safety has been ensured. Our main approach is as follows.
