摘要
潘三矿1452(3)工作面在复合顶板、三软煤层、最大倾角达32°的条件下实现了无网开采,且平均采高达到了3.7m,实现了复杂煤层条件下工作面的高产高效。
A mining technique without netting was applied in the conditions of compound Roof,“three - soft” seam and large inclined angle in working face NO. 1452（3） , and the average mining height in working face got up to 3.7 meter.This working face realized high production and high efficiency technology in Complex Conditions.
