摘要
通过预热机组对进入井筒冷风进行预热,灵活调整全矿通风系统,同时合理控制进风风量,辅助管理技术手段对多井筒的进风风量及温度进行有效监控,避免冬季井筒出现大规模结冰现象,从而有效保障全矿井筒的安全运行。
The cold air entering into shaft is preheated by preheating unit, and the ventilation system in the whole mine is adjusted flexibly. Using a pre-heater to control the air intake rate and temperature to heat up and ven- tilate the whole shaft network. This method prevents the shaft network from freezing in winter, which provides a safer work place.
