王家寨煤矿通风系统改造与优化

Innovation and Optimization of Ventilation System in Wangjiazhai Coal Mine

王家寨煤矿为中央并列式通风,漏风量较大,主井通风阻力较大。通过对矿井通风系统进行通风阻力测定,发现矿井回风段通风阻力过大且通风难易程度为中等。针对以上情况,结合矿井下组煤的开拓对矿井通风系统进行了改造与优化。

Retrograde ventilation is used for Wangjiazhai coal mine, both air leakage and ventilation resistance of the main shaft are largish. By determining the ventilation resistance of the mine shaft ventilation system, it is found that the ventilation resistance in retum airways is particularly large and the ventilation degree is middle. According to the above mformarion and combining with the development of coal seam undorneath the mine shaft, the innovation and optimization of this system are engaged.
