摘要
针对松软及不均硬矿体采矿中存在的生产能力低、矿石损失大等问题,推广使用了空场一崩落组合采矿方法,改进了低分段崩落法的落矿及运搬方式,从而提高了生产工效和采矿强度。
Bccause of a low productive capacity and a large loss of ore existing in soft and uneven hard ore mining,and openstope- caving combined method is applied,and the mode of collapsing and casting of initial sublevel caving method is improved.Therefore, the product efficiency and mining intensity are increased.
