单翼混合式复杂通风系统降低矿井通风阻力研究

Research on a Hybrid Complex Ventilation System to Reduce Ventilation Resistance of the Mine

兴翟沟(新密)煤矿的开采活动全部集中在矿区东翼,随着矿井开采越来越深,矿井的通风线路也越来越长,通风阻力越来越大甚至超标,相继会出现部分工作面风量不足的问题。矿井面临制定降低通风阻力优化方案的问题。

Xingzhai Gou （Xinmi） coal mine mining activities of all concentrated in the east wing, as themine is getting deeper and deeper, the ventilation resistance is getting bigger and even over the standard, one after another, there will be a problem of insufficient air volume in some working faces. The mine is faced with the problem of formulating the optimization scheme for reducing ventilation resistance.
