协庄煤矿有四个进风井,三个回风井,四个水平,采深达到1200m,矿井自然风压大,通风路线长。矿井每年一次的反风演习,是三个风井同时反风获得的数据,当矿井发生灾变需要反风时,若风机电机烧坏、电控设备失灵、倒机风门打不开、司机操作失误等问题,可能造成三个风井不能同时反风,此时矿井各采区、水平、主要进风巷及回风巷,巷道的风流方向、风量和瓦斯涌出情况,是矿井救援指挥的重要依据。为此,我们分别进行了一个风井反风、两个风井反风和三个风井同时反风的试验,获得了分风井反风的一些实际数据,为今后矿井灾害救援指挥工作提供了技术依据。
Xiezhuang mine has four air intake wells, three return air shafts, four levels, mining depth of 1200m, mine natural wind pressure, long ventilation routes. The mine’s annual anti-wind exercise is the data obtained by the three wind shafts at the same time against the wind. When the mine has a disaster and requires anti-wind, if the fan motor burns out, the electronic control equipment fails, the inverter door can not be opened and the driver’s operation error And other issues may cause the three wind shafts can not simultaneously wind, at this time the mining area, level, the main air inlet and return airways, the direction of the air flow, air flow and gas emission conditions, is the mine rescue command in accordance with. For this reason, we conducted a series of tests including wind shaft anti-wind, wind shaft anti-wind and wind shaft anti-wind at the same time, and obtained some actual data of air-blasting anti-wind for future mine disaster rescue command work The technical basis.
