摘要
通过现场在马头门附近设立监测站进行长期监测井筒地压 ,分析了井筒附近地压活动规律 ,并与数值模拟分析值进行对比验证 ,从而为安全、高效地提前回收保安矿柱提供有力的保障。
The long-term monitoring of shaft geopressure is made by monitoring station established nearby the horsehead door,This paper analyses the regularity of geopressure activity nearby the shaft.Contrasting and verifying with analysed data of numerical simulations,a strong guarantee is provided for safely and efficiently recovery of protecting pillar in advance.
