摘要
介绍了新型致灾气体束管监控系统的组成、工作原理和特点,利用其对矿井巷道和密闭内的气体进行实时监控。根据超前预爆破发生时间对矿井气体浓度变化进行研究分析,进一步分析得出急倾斜煤层开采过程中巷道和密闭内气体浓度的变化规律,为后续防灭火和生产工作提供参考。
The composition, working principle and characteristics of the new type of gas storm monitoring system are introduced, and it is used to monitor the mine in the mine roadway and the enclosed gas in real time. According to the pre-blasting time, the change of mine gas concentration is analyzed, and the change rule of the gas concentration in the roadway and the closed gas during the mining process is analyzed; It provide the reference for the subsequent fire prevention and production work.
