Through cooperative work of a cooperative service module, a working face data management module, a prediction service module, a movement deformation prediction module, a movement deformation contour map generation module, a movement deformation profile map drawing module, a damage grade cloud map drawing module and a movement deformation information statistics module, the damage grade cloud map is obtained; efficient acquisition of the current situation information of the mine stope face, efficient calculation of movement deformation prediction and visual display of a surface movement deformation prediction result are realized; an intuitive and efficient technical tool is provided for researching a mining surface movement deformation rule and improving a mining subsidence damage prevention and control technology; the mine production planning work quality and efficiency areimproved, and the stope face data are stored in the spatial database, and unified storage, real-time sharing and repeated utilization of the data are achieved; and the problem that in the prior art,mining subsidence cannot be accurately predicted before coal resources are mined is solved.

Description

technical field [0001] The invention relates to the technical field of coal mine geological surveying, in particular to a system for predicting and analyzing mining surface movement and deformation. Background technique [0002] Prediction and forecasting of mining subsidence is one of the core contents of the subject of mining subsidence, and it is of great significance to the theoretical research and production practice of mining subsidence. The results of mine subsidence prediction can be used to quantitatively study the time and space distribution of rock formations and surface movements affected by mining. The results of mining subsidence prediction are often used to judge whether buildings are affected by mining and the degree of mining impact, as the basis for repairing, strengthening or taking underground mining measures for affected buildings; the results of mining subsidence prediction can be used to fully grasp The subsidence of the land in the mining area, inclu...

AI Technical Summary

Problems solved by technology

[0003] Although several prediction systems for surface movement and deformation have appeared in the industry, which can simply predict the movement and deformation of the mining surface, it has been found through research that these prediction systems are complex in operation, poor in compatibility, and low in visualization. too long or unpredictable

The reasons: First, because the core algorithm of mobile deformation prediction is not packaged into a service design, resulting in low system operation efficiency, poor compatibility, integration and scalability; second, the management of a large number of coal seam mining face data It only uses text input and output, and does not use spatial database management, resulting in cumbersome user operations, inability to manage data in a unified manner, poor timeliness, and inability to be shared by multiple users. The method is relatively simple
