The invention relates to the technical field of monitoring, and discloses a monitoring device for surface settlement deformation of coal mining subsidence areas. The monitoring device comprises a plurality of expansion links, wherein the expansion links are hollow structures; air bags are sleeved at the tops of the expansion links; the air bags are in communication with the inner parts of the expansion links; the expansion links comprise a plurality of tubular bodies; the adjacent tubular bodies are glidingly connected; a reaction mechanism is arranged on the top of each tubular body; the reaction mechanisms can cause the expansion links to contract when the ground surfaces settle; and confirmation mechanisms are arranged between adjacent expansion links. The monitoring device is capable of effectively and quickly monitoring and predicting the settlement deformation processes and changing trends of the coal mining subsidence areas in the southwest mountainous areas, so that benefit isbrought to people to make next decisions and arrangements, and the harms caused by surface settlement to the life and properties of people are decreased; and meanwhile, monitoring results can be further confirmed, so that the accuracy of the monitoring results is greatly improved and necessary information support is provided for comprehensive improvement of geological environment of mines.
Description
technical field [0001] The invention belongs to the technical field of monitoring. Background technique [0002] Coal accounts for about 75% of my country's energy structure, plays an important role in national economic and social development, and has made outstanding contributions, but at the same time it has also produced a series of problems, such as environmental pollution, landslides, and surface subsidence deformation Among them, the problem of surface subsidence and deformation is the most prominent, and some mining areas even have subsidence, which has brought a huge threat to the life, property and ecological environment of the local people in the mining area. Effective monitoring of ground deformation caused by coal mining will provide important basic data for the management of the geological environment in mining areas, and provide a scientific basis for relevant departments to formulate management plans. [0003] Most of the traditional ground deformation monitor...
