茶山矿南矿段通风系统改造研究

摘要

为解决茶山矿南矿段自然通风系统通风能力不足、井下通风困难等现状，详细分析了通风系统存在的问题，通过现场实测数据论述了通风系统改造的必要性，并结合矿井的实际情况和生产计划的具体要求提出了针对性的改造方案。改造完成后，对通风系统的实际效果进行测定，结果表明：改造后的矿井通风系统已符合有关规程的规定，井下温度已全部降到28℃以下，矿井有效风量率达到90.98%，工作环境得到大大改善，保障了矿井的安全高效生产。%Based on the current problems of ventilation system in the Southern Section of Chashan Mine, including inadequate natural ventilation and underground ventilation, this paper puts forward some corresponding transformation technologies by analyzing the field investigation data. The testing results after ventilation system transformation show the underground temperature lowers than 28℃with cross air flow rate reaching 90.98%. The transformed ventilation system conforms to related regulations with increased working environments.
