为掌握响水煤矿山体地质灾害的实时状态及变化情况,对滑坡体全要素数据进行实时监测,提出了一套基于MEMS三轴加速度传感器和MEMS陀螺仪的山体地质灾害监测技术,介绍了关键技术原理,分析了监测误差的关键参数并建立误差修正模型,制定了标定试验步骤,在工程案例中对结果进行了验证.工程应用试验结果表明,经过温度误差改正,该系统测量精度可达0.2 mm,分辨率和灵敏性优于0.1 mm,长期稳定性可达0.2 mm,可准确判断山体地质灾害的隐伏滑面为地面下13.0 m处,计算该隐伏滑坡体的方量和下滑力,满足山体地质灾害全要素长期实时监测和预测预警的需要.
In order to grasp the real-time state and changes of of geological disasters in the Xiangshui Coal Mine,real-time monitoring of all element data of the landslide body is carried out.A set of mountain geological hazard monitoring technology based on MEMS three-axis acceleration sensors and MEMS gyroscopes was proposed,revealing the key technical principles.The key parameters of monitoring errors were analyzed,and an error correction model was established.Calibration test steps were formulated,and the results were verified in engineering cases.The results of engineering application tests show that after temperature error correction,the accuracy of the system can reach 0.2 mm,the resolution and sensitivity are better than 0.1 mm,the long-term stability can reach 0.2 mm.It can accurately judge that the hidden sliding surface of the geological hazard of the mountain is 13.0 m below the ground,calculate the volume and slid-ing force of the hidden landslide body,and meet the needs of long-term real-time monitoring and prediction warning of all elements of mountain geological disasters.
