Problems solved by technology
[0005] The purpose of the present invention is to solve the problem that the rock movement observation station cannot be installed on the main section, and provide a method for obtaining the subsidence value of points on the main section at any time, by measuring the data of monitoring points on the irregular rock movement observation line. Calculate the rock movement data of points on the main section to achieve the same effect as the construction of rock movement observation stations on the main section

Embodiment Construction
[0033] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. The specific embodiments described here are only used to explain the present invention, not to limit the invention.
[0034] This embodiment provides a method for obtaining the sinking value of a point on the main section at any time, including the following steps:
[0035] S1. Obtain the data of monitoring points on the irregular rock movement observation line, and integrate the plane coordinates of the monitoring points as the starting coordinate data on the irregular rock movement observation line;
[0036] In the embodiment of the present invention, due to the complex terrain and lush vegetation in the main section area, the staff cannot enter and establish rock movement observation stations, so the rock movement observation stations are arranged in places with open groun...

The invention discloses a method for acquiring a subsidence value of a point on a main section at any moment, and the method comprises the following steps: processing irregular rock movement observation line data, establishing mapping between a monitoring point on an irregular rock movement observation line and a corresponding point on the main section, and solving the problem that the subsidence value of the point on the main section cannot be directly solved; establishing a plurality of subsidence value function equations through enough monitoring point data on an irregular rock movement observation line, so the precision of the subsidence value function equations in the aspect of unknown parameter solving can be improved, and then high-precision subsidence values of points on a main section are obtained; by constructing the subsidence value function of the points on the main section based on the time influence function, the subsidence value of the points on the main section at any moment can be solved, and the method has great significance in the aspect of surface subsidence early warning.
Description
technical field [0001] The invention relates to the field of rock movement and deformation monitoring, in particular to a method for obtaining the subsidence value of a point on a main section at any time. Background technique [0002] Years of research on coal mine surface mobile observation stations have shown that the law of surface movement and its predicted parameters have regional characteristics. To this end, each mining area has a purpose to carry out on-site monitoring of surface movement, summary of laws, and estimation of estimated parameters, so as to solve the mining subsidence and "three under" coal mining problems in the mining area. The main purpose of setting up the surface mobile observation station is: ① obtain the law of surface movement and deformation after coal seam mining in this area, and provide the basis for the overall planning, environmental assessment and mine design of the mining area; ② provide technical parameters for the safe and reasonable ...
