摘要
均压通风技术已成为火区下采煤工作面常用的成熟技术,均压效果的好坏对于火区下回采和回撤期间的工作面有重大影响,以气体监测为主的预测预报方法是反映是火区下工作面防灭火安全状况的有效措施。以五虎山矿1201工作面为实例,重点对工作面回撤期间气体监测方案进行研究,指出了监测的重点位置和监测方法。
Pressure balancing ventilation method has already become a mature technology and widely used in working face under the mine fire, the good and bad effects of this technology have great influence on the working face during the period of mining and withdrawing. The predict method based on the gas monitoring is useful measures to reflect working facet safety situation. The paper takes Wuhushan Mine 1201 working face as an example, the main point of the research is the plan of gas monitoring during the withdraw period.
