Abstract: In order to solve the problem of low equipment withdrawal efficiency and high safety risk in the fully mechanized mining face of Wangpo coal mine, and achieve the goal of reducing personnel, in the process of equipment withdrawal in 3314 fully mechanized mining face, innovation and optimization are carried out from the aspects of improving the final mining support technology, changing the withdrawal equipment, improving the withdrawal technology and optimizing the auxiliary transportation system, new materials, new processes and new equipment such as "shotcrete anchor" support (shotcrete, grouting and anchor cable reinforcement) technology at the stoping line, full section high-strength polyester fiber mesh, support withdrawal and direction adjustment platform, continuous and uninterrupted transportation from the shaft bottom yard to the withdrawal channel are adopted in the first time. It has changed the traditional retraction mode with winch as the main retraction equipment and track transportation as the main auxiliary transportation mode, completed the equipment retraction of 3314 fully mechanized mining face safely and efficiently, achieved good application effect, and explored a new path for the equipment retraction of fully mechanized mining face in Wangpo coal mine and other similar conditions.
