摘要
根据宋楼煤矿的生产布局,矿井的生产区域将由浅部的11、12采区转移到深部的13、14采区,通风系统有较大改变。由于进入深部采区时,可能会出现瓦斯涌出量增大,地温增高,通风线路延长、阻力增大,井下风量调节困难、增风不易等问题,所以需要对矿井通风系统进行改造。改造的首要任务就是更换矿井主要通风机。为了使新风机安全、经济、合理地运行,在投运时需要进行计算机模拟通风网络解算,因此,在矿井主要通风机性能测定与通风阻力测定的基础上,利用专用模拟通风网络解算软件,确定了新风机挂网运行角度,保证了新风机及井下通风系统平稳运行。
According to the production layout of Songlou Coal Mine,the mine production area transfered from 11,12 mining area of shal- low part to 13,14 mining area of deep part, so the ventilation system will make great changes. In the deep part of mine production area, the gas emission might increase, geothermal temperature increased, the resistance increased, when ventilation line extension, difficulties such as underground air volume regulation and increasing wind, so it was needed to transform the ventilation system of coal mine. The primary task of reconstruction is the replacement of main mine ventilator. To make new mine ventilator run safely, economically and rea- sonably, computer simulation ventilation network calculation should be carried out before the mine ventilator runs. Therefore, based on the main ventilator performance measurement and ventilation resistance measurement of coal mine, the new ventilator operating angle was confirmed by using the special software for simulate ventilation network calculation, which ensured the new mine ventilator and the underground ventilation system running smoothly and steadily.
