针对千秋煤矿进入深部开采瓦斯涌出量增大,用风地点增多,通风能力不足的问题,对矿井通风系统进行了技术测定,分析了通风容易和困难时期的生产部署和配风情况,并提出通风系统优化改造方案,利用计算机对各个时期进行解网分析,最终确定矿井主要通风机的型号。该方案可大幅增加矿井供风量,保证矿井的安全生产。 Aiming at the problem of increasing gas emission, windy location and lack of ventilation in the deep mining of Qianqiu Coal Mine, the ventilation system of the mine was measured and the production deployment and gas distribution in the difficult and difficult times were analyzed. Ventilation system optimization and transformation programs, the use of computer network analysis of various periods, and ultimately determine the type of mine’s main fan. The program can significantly increase the amount of mine air supply to ensure mine safety.
