摘要
河台金矿开采急倾斜、薄矿体、矿岩中等稳固的蚀变糜棱岩型金矿床。历年以浅孔留矿法为主要采矿方法 ,并辅以干式充填、小分段中深孔空场等回采工艺 ,近年使用人工矿柱及类框架结构支撑采空区等新技术 ,使采矿工艺更加完善。采矿技术进步对矿山生产起到促进作用。
Alteration mylonite gold deposit, which is steeply dipping and narrow vein together.With middling steady ore and rock is mined in Hetai gold mine, the shore holl shrinkage is used as the main mining means for several years, also with mining technologies such as dry filling stoping and small subsection middle long holl empty stoping. In recent years, technology of artifical pillar and sirnilar frarne work, structure supporting emptied stope make the mining technology more perfect. The progress of mining technique promote the mine production.
