我矿是1959年投产的,开采十个煤层,其中三、五、六层煤均属于自然发火煤层。目前矿井有两个水平,五个水仓,水仓容积:一水平935.5立方米,二水平997.24立方米,总计1932.74立方米。随着生产的发展,开采水平的延深,矿井予防性灌浆工程量的增大,加快了水仓的淤积。矿井正常涌水量为40立方米/小时左右,加上灌浆、防尘水,最大涌水量为120立方米/小时。水仓淤积速度:一水平约3立方米/日,二水平约4立方米/日。因此,一般200多天就得清理一次水仓,否则,就要威胁矿井的安全生产。
Mine was put into operation in 1959, the mining of 10 seams, of which three, five, six layers of coal are spontaneous coal seam. At present, the mine has two levels, five water tanks, water storage capacity: a level of 935.5 cubic meters, two levels of 997.24 cubic meters, a total of 1932.74 cubic meters. With the development of production and the deepening of the exploitation level, the amount of preventive grouting works in mines has increased, which has accelerated the siltation of water storage. The normal mine water inflow of 40 cubic meters / hour, with grouting, dust-proof water, the maximum inflow of 120 cubic meters / hour. Silo deposition rate: a level of about 3 cubic meters / day, two levels of about 4 cubic meters / day. Therefore, usually more than 200 days have to clean up a water tank, otherwise, it is necessary to threaten the safety of mine production.
