一、概述我矿现有4对矿井:一对平峒、两对斜井、一对竖井。除4竖井为低沼气矿井外,其余均为高沼气矿井,而一号井平峒还伴有煤与瓦斯突出。盘区上下山布置,走向长为1000～1500m,倾斜长为800～1300m。采用走向长壁工作面和倾斜长壁工作面开采,工作面长一般为120～180m,全部陷落法管理顶板。近几年来,随着矿井产量的增加,矿井沼气涌出量也相应增加,单靠风排出工作面涌出的瓦斯是难以维持生产的。目前,我矿 First, an overview My mine has 4 pairs of mines: a pair of flat 峒, two pairs of inclined wells, a pair of shafts. Except 4 shafts are low-methane wells, the rest are high-methane wells, while No. 1 wells are also associated with coal and gas outburst. Panel layout up and down the mountain, to the length of 1000 ~ 1500m, tilt length of 800 ~ 1300m. The use of longwall face and tilt longwall face mining, working face length is generally 120 ~ 180m, all the law of the sinking roof management. In recent years, with the increase of mine output, the amount of mine methane emission also increases correspondingly. It is difficult to maintain the production of methane gushed out by the wind by the wind. At present, I mine
