摘　　要：倾角10°～40°、厚度1～6m的缓倾斜至倾斜薄矿体的采矿方法，一直是一个困扰矿山生产的技术难题，很多矿山因此而制约了经济的发展。特别是黄金、钨、锑等富贵金属矿，多年来，大量的工程技术人员一直在不断的探寻和研究适宜的采矿方法，但仍收效甚微。为探求此类型矿体较好的采矿方法，针对我国东北地区的一个典型的黄金矿山，详细分析了其开采技术条件，对国内外类似矿山的生产经验进行了调查，对比分析了电耙留矿采矿法等3种采矿方法的技术经济指标和优缺点，研究了在不充填的条件下的特殊空场采矿法——倾斜分条房柱采矿法，经试验取得了高效率、低贫化、低损失的技术经济效果。The mining method of the gently inclined to in- clined and thin ore-body , with dip angle from 10°to 40°and thickness of 1-6 m is always a difficult problem to limit the economic development of many mines. Especially in the pre- cious metal mines, such as Gold, Tungsten and Antimony deposits, a large number of engineering and technical per- sonal have been continuously research on the safety of min- ing methods over the years, but with little effect. In order to seek a suitable mining method for this kind of ore-body, tak- ing a typical gold mine in the northeast of China as an exam- ple, the mining technical conditions were analyzed in detail, the production experience in similar mines at home and a- broad were investigated, technical and economic indexes, aswell as advantages and disadvantages of three mining meth- ods including the scraper shrinkage stoping method were compared, and a special open stope mining method without filling, that is inclined strips room-and-pillar method, was put forward and proved by test to obtain good technical and economic results of high-efficient, low dilution and low loss.
