摘要
为了改善山西吕梁中阳付家焉煤业有限公司矿井通风系统存在的不足之处,减少资源及人力的浪费,对矿井通风系统现状进行分析,确定了付家焉煤矿矿井通风系统存在的弊端,通过对南翼老采区进行封闭,改变矿井瓦斯抽放方式和砌筑、拆除巷道密闭来优化调整矿井通风系统。在改变矿井抽放瓦斯方式及通风系统后,南翼采区瓦斯抽放量由原来管路抽放的瓦斯量11.31 m3/min改为巷道抽放后的瓦斯量11.77 m3/min,每天多抽纯瓦斯量662.4 m3/d;矿井瓦斯发电利用率大大提高;专业进风井和集中进风巷充分发挥作用,通风系统更加稳定可靠。
In order to improve the deficiency of ventilation system in Shanxi Lyuliang Zhongyang Fujiayan Coal Limited Company, re- duce the waste of manpower and resource, based on the analysis of the current situation of coalmine in Fujiayan Coal Mime, we find the drawbacks ir/the mine ventilation system. By closing the old mining area in south wing and changing the way of mine gas drainage, constructing and dismantling fire dam to optimize and adjust mine ventilation system, it changes the methane drainage in south mining area from 11.31 m3/min by pipes to 11.77 m3/min by tunnel, with an increase of 662.4 mZ/d, which improved the utilization of the gas for power generation. The intake ventilation shaft and tunnel give full play to the stabilization and reliability of ventilation system.
