我国岩金现代地下开采技术综述

Technological Summarization of Domestic mining Techniques of Rock Gold

我国黄金矿床经历60多年开采之后,目前仍然以岩金开采为主,伴生金与砂金为辅,在岩金开采中,仍然以地下开采为主,露天为辅;在地下开采三大类采矿方法中,以浅眼留矿法为主、全面和房柱法为辅的空场法到21世纪初期仍占60%以上,充填法约占30%左右,其余是崩落法和其它相结合方法。就21世纪初期我国岩金地下开采的技术特点及发展方向等问题,阐明作者观点,敬请同仁们赐教。

After over 60 years mining of domestic gold deposit,the major mining ores is rock gold and accessorial accompanying and sandy gold.The key mining rock gold method is underground accessorial open.In the three underground mining methods,shallow hole shrinkage stoping method is major accessorial open stope method of total and room-pillar method accounting up 60%to 21 century,filling method accounts about 30%,other is caving method and other combined methods.Introduced the author's opinions of the technological feature and developing directions of underground mining of rock gold.
