Technical Field

The invention relates to the technical field of goaf subsidence monitoring, in particular to a goaf area monitoring device.

Background

The large-scale development and utilization of mineral resources bring great social and economic benefits to human beings, and also cause a series of environmental problems and mining damages to the production and life of human beings. The goaf is formed after the minerals are mined, and the upper rock stratum of the goaf deforms under the action of gravity and the like and is spread to the ground, so that the goaf subsidence is one of the main artificial geological disasters. The current mining area monitoring mostly adopts equipment such as total powerstation or GPS, the cost is higher, it is comparatively loaded down with trivial details to install and use, be unsuitable for mining area large tracts of land subsidence monitoring, and some other monitoring devices mostly can only monitor the total settlement volume on ground, can not monitor different soil layer settlement volumes, be difficult to for the prediction of subsidence calamity, the loss assessment provides corresponding data basis, the practicality is not strong, therefore, an urgent need for a simple structure, low cost can monitor a mining area monitoring device to different soil layer settlement volumes again.
