Abstract:

Shun he first coal mining face for the first oblique isometric tone design that will face cut position on the basis of the initial design to the head position as the center, clockwise 16 °, after tune after ramp may face increased 11575t mining resources; oblique after adjusting for the face, designed with a combination of the actual situation as long oblique tone recovery process, after calculation, transfer per cycle in accordance with the oblique head into a knife blade tail manner into five recovery. Engineering practice shows that the scheme not only improves the recovery rate, but also to solve the long-tune oblique face such challenges, the smooth realization without frame, without tank, do not brush the face of equal length to help tone oblique, research results face tone oblique design and stope mining with a reference value.

Key words: First mining face, Regulate Inclination, Actual situation, Mine
