Mine ground surface settlement monitoring system

Abstract

The invention relates to a mine ground surface settlement monitoring system which comprises a plurality of GNSS reference stations, a wireless network and a monitoring and early warning host. The GNSS reference stations are arranged on the ground surface of a mine monitoring area. Each GNSS reference station comprises a GPS host, a wireless communication module and a power supply module which are installed on a vertical pier column. The GPS host receives continuous GPS positioning information sent by the CORS system, generates real-time three-dimensional GPS positioning data of the earth surface, and sends the real-time three-dimensional GPS positioning data to the monitoring and early warning host through the wireless communication module via a wireless network; the CORS system sends GPS positioning information to the GPS host and generates corresponding surface subsidence data of the GNSS reference station through processing, and the surface subsidence data is transmitted to the monitoring and early warning host in real time through the CORS system; and the monitoring and early warning host receives the real-time three-dimensional GPS positioning data and the real-time surface subsidence data. The mine ground surface settlement monitoring system can monitor mine ground surface settlement in real time and has the advantages of being stable in system, capable of achieving all-weather monitoring and long-distance information transmission and flexible and diverse in early warning mode.

Description

technical field [0001] The present application relates to the technical field of geological monitoring, in particular to a mine surface subsidence monitoring system. Background technique [0002] With the rapid development of economy and society, the demand for mineral products is increasing, and many minerals need to be mined underground. Due to the stress balance factor, with the increase of the volume of the mining area and the passage of time, the surface of the mining area often results in subsidence or Subsidence will affect the safe production of mines; it will cause damage to farmland, damage to ground buildings, and change the surface environment. [0003] Therefore, it is necessary to effectively monitor the surface subsidence in the mining area, but the existing monitoring methods are relatively backward, and hand-held GPS measuring instruments and manual visual monitoring are still used. The monitoring tools are mainly GPS, steel tape measure, benchmark, tape mea...

Problems solved by technology

[0002] With the rapid development of the economy and society, the demand for mineral products is increasing, and many minerals need to be mined underground. Due to the stress balance factor, with the increase of the volume of the mining area and the passage of time, the surface of the mining area often results in subsidence or Subsidence, thereby affecting the safe production of mines; causing damage to farmland, damage to ground buildings, and changes to the surface environment

[0003] Therefore, it is necessary to effectively monitor the surface subsidence in the mining area, but the existing monitoring methods are relatively backward, and hand-held GPS measuring instruments and manual visual monitoring are still used. The monitoring tools are mainly GPS, steel tape measure, benchmark, tape measure, etc. The measurement accuracy cannot meet the monitoring requirements of the mine geological environment, the monitoring data collection is inconvenient, and the accuracy and continuity of the data cannot be guaranteed. Further improvement is urgently needed to ensure the safety of the land and residents around the mining area
