Description

technical field [0001] The system relates to a special railway transportation system for mining, more specifically, it relates to an intelligent prediction and control safety transportation system for mining subsidence under special railway turnout groups, and belongs to the technical field of railway transportation. Background technique [0002] At present, large-scale modern mining at home and abroad has a high degree of comprehensive mechanization. With the continuous advancement of mining work, the working face is gradually approaching the lower part of the special railway in the mining area. The mining of these working faces will directly threaten the safety of railway transportation and production in mining areas. At the same time, during the mining period of extra-thick ore seams, the surface variables of the railway subsidence area are large, the subsidence speed is fast, and the railway transportation cannot be interrupted, the maintenance of the line is complicate...

Problems solved by technology

Although China has made considerable progress in the basic theory of mining subsidence, it is mainly the basic theory, simulation model, calculation method, etc., and the development of computer software is also based on part of the theory for simulation design; in terms of mining subsidence prediction technology, currently It is mainly based on the actual situation of the relevant mining area, select the appropriate prediction model in the prediction method, and only predict the general geological mining conditions, but for the special geological and mining conditions, the current software does not have a relatively mature prediction method and Corresponding to the technical system; the current software system generally has the functions of observation station data management and data processing, reference function, prediction function and graphics drawing function. Although it also involves the application of computer technology and expert system theory, it basically stays in a single The prediction of surface deformation and the deformation control of buildings; the mining subsidence information system is only formed by using the basic theory of information system and database management system, it is only the management of parameter prediction and prediction system, and the mining subsidence expert formed by using the basic theory of expert system The system is also only positioned on the layout of surface buildings and underground mining work, as well as the research on mining technology; the nonlinear fitting performed by using ANASYS software and MATLAB software is also mainly to study the rock formation damage and movement from the mining seam to the surface

[0004] At present, the relevant technical achievements at home and abroad focus on the application of the surface deformation prediction system and the research on the failure law of the overlying strata, but the mining subsidence prediction and control system of the railway in the mining area, especially the station turnout group, have not been carried out. Relevant studies have not yet seen reports on the prediction and control of railway station yard deformation and safe transportation technology under the condition of fully mechanized caving mining in extra-thick ore seams
