摘要
介绍了高应力下高分段空场嗣后充填法的试验,该采矿工艺的全面推广不仅降低了施工工艺的复杂程度、减少了掘进工程量,而且较大程度地提高矿石回采效率,降低了采矿成本,取得了良好的经济效益和社会效益。
The test of high-sublevel open stoping with subsequent backfilling under high stress was introduced. The overall spreading of this mining technology not only reduced the complexity of construction process and the amount of tunneling engineering, but also greatly improved the mining efficiency, reduced the mining cost, and it achieved good economic and social benefits.
