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 equalization ventilation technology has become a mature technology commonly used in coal mining face under fire zone. The effect of pressure equalization has a significant impact on the working face during the process of recovery and withdrawal under the fire zone. The predication method based on gas monitoring Reflect the fire area under fire prevention and fire safety status of the effective measures. With the example of 1201 working face of Wuhushan Mine, the gas monitoring scheme during the work face retracement is emphatically studied, and the key monitoring locations and monitoring methods are pointed out.
