Abstract:

Through fully-mechanized mining fast docking technique theory is analyzed, and combination of Guqiao coal mine, 1121 (1) the specific conditions of fully mechanized working face, and put forward the base line determination, stent azimuth control, elevation and conveyor slope control etc docking effective method. Further illustrates the butt the preparing work before, face butt and equipment docking process, summed up the feasible fully butt technology. Through the scraper conveyor butt joint spacing validation, and the results show that face a butt joint success, when using only 16 h. The technology in the implementation of Guqiao coal mine,not only technically feasible and economically reasonable ,effectively solve the mine irregular shape area mining technology problem, improve the recovery rate of resources. The mine mining, especially the exhaustion of resources type mine reserves potential has certain reference significance.

Key words: Complicated Conditions, Fully-mechanized Mining, Fast Docking Technology
