摘要

设计制定了通风阻力测定方案,对A煤矿+800 m水平主要路线的进风段、用风段、回风段进行了通风阻力测定。测定和计算结果显示,各段通风阻力差别较大,矿井总进风量为1 512 m3/min,难以满足后续工作面接替时的通风需求。为此,制定了系统改造优化方案,改造后实现了采区风量向风井的合理分流,总风量达到3 048 m3/min,保证了安全生产。
        This paper designed and formulated the ventilation resistance measurement scheme, and measured the ventilation resistance of the air inlet section, the air using section and the air return section of the main route of A Coal Mine +800 m level.The results of measurement and calculation showed that the ventilation resistance of each section was quite different. The total air intake of the mine was 1 512 m3/min, which was difficult to meet the ventilation demand of the follow-up working face. For this reason, the optimization scheme of the system transformation was formulated. After the transformation, the reasonable diversion of the air volume from the mining area to the air shaft was realized. The total air volume reached 3 048 m3/min, which guaranteed the safe production.
