Research The Regularity Of Surface Movement And Deformation

With the coal seam ongoing mined, original equilibrium stress of rock surround the seam will be broken, the destroyed Stress will reach equilibrium again as time goes on. The coal be mined surrounding the rock will continue deformation, move or even destruction, the surface above the mined coal seam will sink when this damage reaches a certain level, at the same time this surface subsidence will bring irreversible impactions and damage to surrounding people’s normal life and the environment. The law of surface movement and deformation is the main content of this research, the focus of this paper is based on the raw data of surface movement observation, further obtained the corresponding surface movement parameters and visualization.In this paper, taking Qingdong coal’s first mining face of726as example, Emplaced surface movement observation station, analysis and processing for five observational data analysis and processing, obtain comprehensive observed data after mining, in which settlement error is1.7mm, the horizontal position error is3.2mm. Get the boundary corner, mobile angle, crack angle are measured parameters, the subsidence coefficient, main influence tangent, inflection point mobile distance, angle of maximum subsidence belongs to the expected parameters. Using probability integration method to calculate projected parameters, summarizes the surface movement regularity of the geological and mining conditions, and achieves its visualization.This article mainly uses visual programming statements, development and preparation the surface movement and deformation visualization program. The results of this research have a guiding role to the mines with similar mining conditions and other face of mines.
