| Abstract: | The arrangement of reasonable cutting engineering,such as adding cut drafts and raises,cutting slots in some mining entrances,and the regulation of production schedule were made for settling unbalance problem of three grade reserves in the production process of non-pillar sublevel caving method,With these measures taken,the mining reserves are increased and three grade reserves are balanced.At same time the ventilation condition and the production efficiency of mining are improved.That guarantees the contin... |
