Trackless Transformation and Equipment Selection of Auxiliary Transportation in Shaft Coal Mine
HAN Fei
Abstract：In order to improve the transportation efficiency of the auxiliary transportation system in a certain shaft coal mine,field research was conducted on the auxiliary shaft lifting system,roadway conditions,auxiliary transportation system,production capacity,and production equipment of the mine.The relevant operating data of the current track auxiliary transportation system in the mine were statistically analyzed,and the contradiction between the transportation capacity of the auxiliary transportation system and the production capacity of the mine was identified.Based on the existing conditions of the mine,a trackless mixed transportation scheme was proposed without significantly changing the current mine conditions,and equipment selection was carried out in combination with the trackless auxiliary transportation technology.Through practical verification,it showed that the track and trackless hybrid transportation system could increase the comprehensive transportation efficiency by 40％compared to the original system,reduce the number of production personnel by 30％compared to the same period last year,and significantly improve production safety.This provides a reference for the design and technological upgrading of auxiliary transportation systems in similar vertical coal mines.
