【摘要】：针对教学二矿通风能力不足,22采区接近结束,随着开采深度增加,可能出现工作面及采空区瓦斯浓度增大的问题,对教学二矿通风系统进行了分析与测定,提出了3种优化改造方案。运用计算机分别解网分析了3个方案,并进行了资金的预算与效益的分析,最后确定了方案Ⅲ为最佳的优化方案。
[Abstract]:In view of the shortage of ventilation capacity in No.2 Mine, near the end of the mining area, with the increase of mining depth, the gas concentration in the face and goaf may increase, the ventilation system of the No. 2 Mine is analyzed and measured. In this paper, three kinds of optimal transformation schemes are put forward, and three schemes are analyzed by using computer respectively, and the budget and benefit of funds are analyzed. Finally, scheme 鈪，
