摘    要：中国黄金矿床经历60多年开采之后,目前仍然以岩金开采为主,伴生金及砂金为辅,在岩金开采中,仍然以地下开采为主,露天开采为辅。在地下开采三大类采矿方法中,以浅眼留矿采矿法为主、全面和房柱采矿法为辅的空场采矿法到21世纪初期仍占60%以上,充填采矿法约占30%左右,其余是崩落采矿法和其他组合采矿法。详述了21世纪初期中国岩金地下开采工艺技术特点,探究了中国岩金地下开采采矿技术研究方向,供采矿同仁参考。

Abstract: In the last more than 60 years,the gold mining industry in China is mainly rock gold mining,with associated gold and placer gold as subsidiary. The rock gold mining is mainly underground mining,with openpit mining as subsidiary. Open stope method,which is dominated by shallow-hole shrinkage method and with overall method and room-pillar method as subsidiary,accounts for more than 60 % in early 21st century. While,the backfill method accounts for about 30 % . The caving method and compounding methods account for about 10 % . The paper discusses the technical features of rock gold underground mining in China in early 21st century and explores the research direction.
