Intelligent control method and system for fully mechanized mining device used for complex condition working face

Abstract

The invention aims to solve the problem of equipment interference, abnormal mechanical conditions and the like due to excessive error accumulation after multiple cycles in a current automated mining system under complex geological conditions, and discloses an intelligent decision control method and system for a fully mechanized mining device used for a complex condition working face. The intelligent decision control system comprises a full posture measurement system for the fully mechanized mining device, a mine pressure monitoring system, a virtual simulation system, an analysis and decisionsystem and a distributed control system. 15 spatial parameters and mine pressure data of the real-time operating state of the device are measured comprehensively, the real mining process is simulatedthrough data superposition, the device abnormalities caused by the complex geological conditions are calculated, the surrounding rock state is predicted, error elimination and surrounding rock controlmethods based on known process methods and historical data learning results are proposed, and subsequent mining control parameters are predicted; and based on real data and virtual simulation results, the optimization and decision-making of underground comprehensive mining device control parameters are completed, so as to ensure that device control under the complex geological conditions can be consistent with actual environmental conditions, and the operation quality of the fully mechanized mining device is greatly improved.

Description

technical field [0001] The invention relates to the field of equipment control of coal mine fully mechanized mining face, in particular to an intelligent decision-making control method and system for fully mechanized mining face equipment. Background technique [0002] After decades of continuous large-scale development of coal, shallow resources have become less and less, and the mining depth has continued to increase. Deep mining is faced with multiple factors such as high ground pressure, high ground temperature and complex geological conditions. As the core operating system of underground mining, the complete set of fully mechanized mining equipment (hydraulic supports, shearers, scraper conveyors, transfer machines and advance support Equipment, etc.), in the dynamic environment of surrounding rock deformation and mine pressure impact, the originally neat and coordinated equipment group randomly tilts and shifts with the roof, floor and coal seam conditions, and cannot ...

AI Technical Summary

Problems solved by technology

These methods are based on sensors, downhole network technology, video technology, etc. to centrally control the equipment of the fully mechanized mining face, but the control method is relatively simple, all of which are based on sensor signals for feedback control, lack of comprehensive utilization of data and comprehensive monitoring of the entire fully mechanized mining face. It is difficult to deal with the control of working face equipment under complex conditions
