摘要
简介马鞍山矿山研究院对遵义、斗南、鹤庆等锰矿山的采矿方法和地压活动规律的试验研究工作。经过几年的努力,试验工作取得了较好的效果。矿石回采率由原来的50％提高到80％以上;阶段矿柱回采试验成功后,矿石回采率尚可达到90％。
The paper briefly introduces the experimental work on the mining methods and stope ground pressure laws of Zunyi,Dounan,Heqin manganese mines that were carried out by Maanshan institute. A better result has been obtained on the experiments. The ore recovery rate was from 50% up to more than 80% ;when the test of step pillar recovering is successful, the ore recovery rate will be expected to 90%.
