摘要
针对永安煤矿以往井下防止瓦斯超限通风装置中滤网容易堵塞且不便于清理等问题,提出了一种新型的防止煤矿瓦斯超限的通风装置。将该装置在永安煤矿3305回采工作面进行了工业性试验,结果表明,应用效果理想,无一起瓦斯超限安全事故发生,同时装置滤网方便拆除,具有提高滤网单次使用时长、操作便捷的优点,保障了井下煤矿开采的通风要求。
A new type of ventilation device to prevent coal mine gas overlimit is provided for the problems of easy clogging and inconvenient cleaning in the previous underground ventilation device to prevent gas overlimit in Yongan coal mine.The results show that the application effect is ideal and no gas overrun safety accident occurred,meanwhile,the filter screen of the device is easy to remove and has the advantages of improving the single use time of the filter screen and convenient operation,which guarantees the ventilation requirements of underground coal mining.
