Estimating mining subsidence under turnout cluster of dedicated railroad, and governing expert system

Abstract

The invention discloses an expert system for estimating and controlling mining damage under special railroad switch cluster, comprising a real- time estimating system of ground surface sinkage on underground mining condition, a real-time estimating system of sinkage deformation of special railroads and stations in mine in mining period, an intelligent estimating and control expert system of sinkage deformation of special railroads in mine, and a safety transportation protection technique against sinkage of special railroads and station switch cluster. And the invention establishes an expert system for estimating and controlling the sinkage of special railroads and station switch cluster in mine in the mining period, revealing characters and dynamic variation law of sinkage deformation of the railroads, thus advancing reasonable railroad maintaining measures, especially a control technique of deformation of railroads and station switch cluster. And the invention is simple and convenient to operate, and has a clear flow, and can make dynamic and steady estimation on mining damage under railroad and station switch cluster, and the estimated result has high accuracy. And the invention can raise total social and economic benefits of thick ledge mining under special railroads in mine.

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
