摘要
浅孔留矿法对急倾斜薄矿脉的矿体开采是一种有效的采矿方法,具有高效低耗与工艺简单等优点。论述了浅孔留矿法新型变形方案:留矿全面法、静态留矿法、削壁留矿法,以及这些方案的矿岩开采条件,采场主动支护,矿柱回收等。
Short-hole shrinkage mining is an effective method for mining steep-thin veins, and it has advantages of high-efficiency and low-waste and simple technology. The new variant schemes about short-hole shrinkage mining(including shrinkage over-all mining, static shrinkage, precipice shrinkage)and rock mining condition, stope active support, pillars extraction are discussed.
