摘要
白象山铁矿采用竖井开拓方式,主要开拓工程有主井、副井、回风井及采区斜坡道。根据矿体赋存情况,矿山现采用上向分层进路充填采矿法与小分段空场嗣后充填采矿法。随着白象山铁矿开采范围的变化,采场作业地点不断调整,矿井通风网络结构发生改变,井下污风循环以及风流短路问题开始出现,通过矿井总风量核算、网络解算分析比较了各通风方案的风机通风阻力、系统实耗功率、系统总风量、系统装机容量等方案的优缺点,综合考虑采区采掘工作面布置,风量合理分配因素,以及系统机站设置方式和风机性能参数,从而确定了最优通风方案,,解决风流短路,增加井下主要生产区域供风,提高了有效风量,确保井下生产安全。
aixiangshan Iron Mine adopts the method of vertical shaft development, which include main shaft, auxiliary shaft, return air shaft and slope of mining area. According to the occurrence of ore bodies, the method of upward slicing and filling and subsequent filling with small sublevel open stope were adopted in the mine. With the changes of the mining scope, working site of the stope and the structure of mine ventilation network of Baixiangshan Iron Mine, the problems of underground polluted air circulation and short circuit of air flow appears. After analysis of the total air volume of the mine, compared the advantages and disadvantages of ventilation resistance, actual power consumption, total air volume and installed capacity of each ventilation scheme using network, the optimum ventilation scheme is determined by considering the layout of the mining face, the reasonable distribution of air volume, the setting mode of the system station and the performance parameters of the fan, in order to solve the short-circuit of air flow, increase the air supply in the main production areas, increase the effective air volume and ensure the safety of underground production.
