LIU Xin-hua
Abstract：In order to improve the roadway maintenance and management level for the advance support area in gob side entry of coal mining face,through the comparative analysis of the advantages and shortcomings between traditional advance support and the sequence or alternate self-moving advance support,based on the advantages,a non-repeated support advance supporting technology was developed.Through the principle analysis of the proposed supporting technology,the available structure of advance supporting units,its arrangement and transportation route in the roadway were give.Aiming at the transportation route,feasible transportation mode was put forward,as well as the moving and deploying measures at both ends of advance support system for the advance support unit.The field application results show that,the advance support technology with non-repeated support is one of the most reliable and effective advance support method for god side entry.
