摘要 矿山深部开采面临岩温升高、通风线路长、网络复杂、主扇压力不足等问题,必须进行深部通风系统改造设计。湖南某铅锌矿二期深部矿体向南侧伏,深部矿石含硫量高、放热量大,通风线路长、阻力大,主扇能力低,新鲜风量不足,热量难以排出,严重影响矿山安全生产。为解决通风困难问题,以现场调查和测定为基础,分析了矿山通风系统存在的关键问题,提出多中段多井并联回风深部通风系统改造方案,利用副斜井、小竖井、回风斜井形成多井并联回风网路,利用上部开采结束的2个中段运输巷并联作为深部回风通道,有效降低矿井通风阻力。方案充分利用现有工程,投资少,见效快,取得了良好工程应用效果,可为类似矿井通风系统改造借鉴。

Abstract: The ventilation system in deep mining is faced with high temperature, long ventilation line, complex network and insufficient pressure of main fan, etc. Reforming design is necessary. Taking the two stage deep mining of a lead-zinc mine in Hunan as an example, the deep ore body is to the south side with high sulphur content, and releasing large heat, the ventilation has long line and large resistance, the main fan is low, the fresh air quantity is insufficient and the heat is difficult to expel, which seriously affects the safety production of the mine. In order to solve the difficult problem of mine ventilation, the key problems existing system are analyzed on the basis of field investigation and determination, and the modification scheme of parallel return air with multi-level drift and multi-shaft are put forwards in deep mining ventilation, The multi-shaft parallel return network is formed by using auxiliary inclined shaft, small shaft and return air well, and two levels transportation lanes in the end upper part are used as the return air passage of the deep mining, which can effectively reduce the ventilation resistance. The scheme makes full use of the existing projects, with less investment and quick effect, and good results in engineering application are obtained, that can be used for the similar transformation in ventilation system.
