摘要
赤峰红花沟金矿在用干式充填采矿法开采急倾斜薄矿脉时，根据矿体赋存规律，因地制宜地划分采场，对多矿块进行了连练回采，取得了较好的效果。解决了采准工作量大、矿块准备时间长等问题，提高了矿块的回采率，期望这种方法能在黄金矿山得到推广。
In the mining of steep dip and narrow vein in Hong-Hua-Gou Gold Mine of Chifeng City by using dry back-filling method, the continuous stoping of multi-block was conducted after the division of stopes according to the occurrence regularity of orebody and specific condition.In this way,the problem of heavy preparatory work load and the longer time of the preparation were solved,thus the stoping rate of block was correspondingly improved.We hope this method can be popularized in gold mines.
