摘要
根据某多金属矿床的赋存情况及开采技术条件,通过对多种适用的采矿方案进行技术分析、经济比较,决定采用阶段大直径深孔采矿尾砂充填法。详细介绍了该采矿方法的采准工程、结构参数、回采工艺及主要技术经济指标。该方法对该矿安全开采有重要意义,对类似矿山的开采具有一定的参考意义。
The bench large diameter longhole backfilling cemen- ted filling method; was introduced based on the technical analysis and economic comparison of the various applicable mining schemes in light of the geological and mining technical conditions of polymetallic d^posit and the occurrence of ore bodies in a mine. The paper introduces in detail the development work, structure parameters, stoping technology and main technical and economic indicators. The use of the method is very important for safety in the mine production and also can serve as a good guidance for mining operation in similar mines.
