摘　　要：赤峰红花沟金矿是内蒙古骨干岩金矿山 ,有 40多年开采历史 ,开采急倾斜薄矿脉矿岩不稳到中等稳固的石英脉型金矿床。自建矿以来一直使用浅孔留矿法 ,但由于矿岩稳固性较差造成大量损失贫化 ,后经金矿工程技术人员共同努力 ,先后改用以干式充填为主的采矿方法 ,并经过不断地完善改进 ,使采矿技术日臻完善 ,企业经济效益也明显提高。Chifeng Honghuagou golden mine is Neimenggu key rock golden mine, have for more than 40 years mine history, mine to worry incline thin mineral ore, mine rock is not steady to go to medium firm quartz pulse type deposit. Since building mine, use shallow hole always to reserve mine law, but since mine rock firmness causes plenty of losses than difference, is poor , after go through gold miner Cheng technical people joint efforts, change to dry type one after another to serve as fill mainly with mining method, and via continuously perfect improvement, make mining technology become better day by day , enterprise economic benefits also rise obviously.
