地质概况矿体为扁豆状,底盘为乌桐石英岩(硬、较稳固),上复阳新石灰岩,乐平煤系及大冶灰岩(中硬、中等稳固),再上层为近代冲积层,矿体平均真厚为11.12公尺,倾斜34°,矿体靠顶盘部分有1～15公尺上宽下窄的老洞,延伸有1百多公尺(大部已充填)。矿石有黄铜矿、辉铜矿、斑铜矿、孔雀石、自然铜等,矿石组成有磁铁矿、磁硫铁矿、黄铁矿、阳起石、辉石等(图1)。在此条件下,此法的优点:
Geological overview The ore body is lentil, the chassis is composed of ukite quartzite (hard and stable), Shangfuyang new limestone, Leping coal system and Daye limestone (medium and medium stable), and the upper layer is modern alluvium. The ore The average true thickness of the body is 11.12 meters with an inclination of 34 °. The upper part of the ore body is covered by an old cave with a width of 1 to 15 meters and a width of more than 100 meters (mostly filled). Minerals are chalcopyrite, chalcocite, bornite, malachite, natural copper, etc. The ore is composed of magnetite, pyrrhotite, pyrite, actinolite and pyroxene (Figure 1). In this condition, the advantages of this method:
