中文摘要:
      GPS技术在通视条件差、地形起伏大的山区仍然拥有进行不间断的连续作业的能力。本文对马各庄煤矿采空区地表岩土体的变形情况进行实时监测,并对采集的变形数据进行综合分析,监测周期为2021年7月1日至12月1日。监测数据表明,马各庄煤矿采空区各监测点位地表岩土体变形主要表现为沉降且中部沉降值明显大于周边区域,经现场调查,与实际状况一致。证明GPS技术在采空区地表岩土体变形监测中同样具备可靠性,能达到对煤矿采空区变形的长期、实时监测的要求。
英文摘要:
      Using GPS technology in poor line of sight, using GPS technology in poor line of sight、mountainous areas with large undulating terrain still have the ability to carry out uninterrupted continuous operations, continuous monitoring of the deformation of surface rock and soil in the goaf of Magezhuang coal mine,finally, and the collected deformation data is comprehensively analyzed.The monitoring period is from 1 July to 1 December 2021.Monitoring data show that the deformation of surface rock and soil at each monitoring point in Magezhuang coal mine goaf was mainly manifested as settlement, and the settlement value in the middle was significantly greater than that in the surrounding area. After on-site investigation, it was consistent with the actual situation. It is proved that GPS technology is also reliable in the monitoring of surface rock and soil deformation in goaf areas, and can meet the requirements of long-term and real-time monitoring of deformation in coal goafs.
