Research Design Of Coal Mine Underground Transportation System And Centralized Control System

As a large coal producer,belt conveyor belt conveyor belt is recognized by most coal mines as the main tool of coal transportation system.Because of the large volume,simple structure,limited by terrain conditions,easy to manage and maintain,high transport efficiency,belt transport system has become an indispensable part of coal production.The improvement of belt conveyor capacity and the realization of automation can improve the coal production efficiency and economic benefits.This paper briefly introduces the development of belt conveyor and its centralized control technology.The status quo of the belt transport system in Xiashijie coal mine is introduced,analyzed the main problems existing in Xiayukou mine belt transport system,put forward the optimization scheme of the dark belt wells four belt into two belt,and the transformation of the two belt centralized control transformation.First of all,according to the Xiayukou mine production needs,related parameters of the two conveyor belt dark well after transformation were calculated and analyzed the power balance control strategy of the belt,select the master-slave control mode;Secondly,based on fuzzy control,the speed regulation speed of some large power belt conveyor is completed by using frequency converter.Finally,centralized control transformation of main belt of dark belt well is carried out by PLC control technology,industrial Ethernet ring network technology,host computer technology and industrial configuration software.The optimization scheme of dark belt wells belt transport system and transformation of centralized control system in the actual application,greatly improve the automation and intelligent level of coal transport capacity,equipment,has been adopted by Tongchuan Shaanxi coal mining limited Xiayukou mine,and dark belt wells four belt conveying system to optimize the transportation system for two the belt scheme and the transformation of centralized control have been implemented and put into use,to achieve the expected goal.
