Abstract：The mine is in sector transition period from the second to the third mining area, the article analyzes and researches the key technology, presents some measures by changing the steering mode, changing the propulsion angle of the semi continuous coal mining system and adjusting the mining layering relationship. The mine fully increases the effective working line length of semi-continuous coal mining system, and forms a reasonable feasible mining area transition project implementation plan, and ensures the annual production capacity during semi continuous mining system sector transition.
