一、留矿法在我国地下矿山的地位及成就 留矿采矿法是我国使用较早,应用较广、效果较佳的一种采矿方法,它对推动我国地下采矿的正规化、机械化起了促进作用。据统计我国有色和稀有金属矿山中,仅用浅孔留矿法采出的矿石量达到全国有色和稀有金属地下开采矿山矿石总量的36%左右。该法在簿和极薄矿脉矿床中使用更广泛。矿石量约占全国脉状矿山总量的80％,这类采矿法已构成我国有色、稀有、黄金矿山采矿方 I. The Status and Achievements of the Mineral Residue Method in Underground Mines in China The left-mining method is a mining method that is used earlier and has a wider application and better effect in our country. It has promoted the regularization and mechanization of underground mining in China effect. According to statistics, among the non-ferrous and rare-metal mines in China, only the ore mined by the shallow-hole retention mining method has reached about 36% of the total amount of the ore mined by underground mining of non-ferrous metals and rare metals. This method is more widely used in books and ultra-thin vein deposits. The amount of ore accounts for about 80% of the total number of vein-shaped mines in the country. This kind of mining law has already constituted the non-ferrous, rare and gold mines in China
