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 methods of gently inclined to oblique thin ore body with inclination angle of 10 ° ~ 40 ° and thickness of 1 ~ 6m have been a technical problem troubling the production of mines. Therefore, many mines restrict the economic development. Especially gold, tungsten, antimony and other rich metal ore, over the years, a large number of engineering and technical personnel has been constantly exploring and researching suitable mining methods, but still with little success. In order to explore a better mining method for this type of orebody, aiming at a typical gold mine in Northeast China, the technical conditions of mining are analyzed in detail. The production experiences of similar mines at home and abroad are investigated. Mining and other three kinds of mining methods of technical and economic indicators and advantages and disadvantages of the study under the conditions of non-filling of the special open-field mining method - inclined sloping house mining method, the test achieved high efficiency, low depletion, Low loss of technical and economic results.
