| 中文摘要: |
| 矿山地表形变是一种常见的灾害类型,是在自然因素和人为因素的双重作用下引起矿区周围岩土体应力状态的变化,导致矿山地表岩土体发生垂直升降运动或者水平运动现象,进而引起岩土体弯曲变形、破裂。矿山地表形变具有形变空间分布密集、强度大的特点,矿山地表形变具有缓慢型和突发型两种类型,前者形变周期长,后者形变时间短,对矿山地表形变监测带来了困难。基于此,文章将北斗系统应用于GPS监测系统中,尝试分析了基于北斗系统的GPS监测系统的形变监测效果。实践表明,该技术可以获得更高的监测精度,对矿山地表形变的动态变化规律有着直观的反应,对研究矿山地表形变规律有着重要的促进意义。此外,将北斗系统应用于矿山地表形变监测中,可以显著提高GPS监测系统的监测精度,能够获得实时动态监测数据,且受监测环境的影响较小,能够输出多元化的监测分析成果图件,提高了监测技术的自动化程度。 |

| The mine surface deformation is a common type of disaster, which causes the change of stress state of rock and soil around the mining area under the dual action of natural factors and factors, which leads to vertical lifting motion or horizontal movement of the surface rock and soil in the mine, and then causes the bending deformation and rupture of the geotechnical body. The surface deformation of mine has the characteristics of dense deformation space distribution and high strength, and the surface deformation of mine has two types, such as slow type and burst type, the former deformation period is long, the latter deformation time period, which brings difficulties to mine surface deformation monitoring. Based on this, this paper applies beidou system to GPS monitoring system, tries to analyze the deformation monitoring effect of GPS monitoring system based on Beidou system, and shows that the technology can obtain higher precision monitoring accuracy, and has an intuitive response to the dynamic variation law of mine surface deformation. It is of great significance to study the variation law of surface deformation in mines. In addition, the beidou system used in the mine surface deformation monitoring, can significantly improve the monitoring precision of the GPS monitoring system, can achieve real-time dynamic monitoring data, and is subject to the influence of environmental monitoring is lesser, can output diverse monitoring datum analysis results, improve the automation degree of monitoring technology. |
