基于北斗系统的GPS矿山地表监测研究

Research on GPS mine surface monitoring based on Beidou system

矿山地表形变是在人为和自然因素的双重作用下引起采空区上部岩土体应力状态发生变化而诱导的形变运动,严重阻碍了矿山的升级发展。矿山地表形变具有明显的滞后性,导致形变监测困难。鉴于此,将北斗系统与GPS监测系统相互结合,以矿山地表形变监测实例分析了该方法的监测效果。实践表明,基于北斗系统的GPS矿山地表形变监测方法具有较高的监测,实现了实时动态监测的目的,且监测成果具有多元化优势,能够直观地反映出形变发展规律;与传统监测方法相比,该方法具有较高的可靠性,说明该方法在形变监测中具有应用优势。

The mine surface deformation is the deformation movement induced by the change of the stress state of the rock and soil mass in the upper part of the goaf under the dual action of human and natural factors, which seriously hinders the upgrading and development of the mine.The mine surface deformation has obvious hysteresis, which leads to the difficulty of deformation monitoring.In view of this, the Beidou system and GPS monitoring system were combined to analyze the monitoring effect of this method with an example of mine surface deformation monitoring.The practice showed that the GPS mine surface deformation monitoring method based on the Beidou system had high monitoring accuracy, achieved the purpose of real-time dynamic monitoring, and the monitoring results had multiple advantages, which could intuitively reflect the development law of deformation.Compared with traditional monitoring methods, this method had higher reliability, which showed that this method had application advantages in deformation monitoring.
