开采技术条件 矿床是中低温热液充填交代多金属硫化物含金石英脉型,除金以外,还含有铅、铜、银等多种金属。 矿床开拓采用平硐溜井开拓方式,阶段高度30~38m。主要矿体的开采技术条件为: 505号矿脉;倾角37°~55°;厚度0.3~3m,平均厚度1.7m;含金平均品位6.98g/t,铅3.253%。 530号矿脉:倾角38°~67°,厚度0.6~3.5m,平均厚度1.32m;含金平均品位11.76g/t,铅3.026%。 两条矿脉上下盘围岩为混合岩、片麻岩和伟晶岩,f=13~15,比较稳固,局部不稳。矿石f=6~10,稳固。
Mining technical conditions Deposit is a medium low temperature hydrothermal filling metasomatic polymetallic sulfide bearing quartz vein type, besides the golden, also contain lead, copper, silver and other metals. The deposit exploitation adopts the way of the development of the mine, and the stage is 30 to 38m. The mining technical conditions of the main ore bodies are: No. 505 vein; the angle of 37 degrees to 55 degrees; the thickness of 0.3 ~ 3M, the average thickness of 1.7m; the average grade of 6.98g/t gold, lead 3.253%. No. 530 vein: the angle of 38 degrees to 67 degrees, the thickness of 0.6 ~ 3.5m, the average thickness of 1.32M; the average grade of 11.76g/t gold, lead 3.026%. Two veins on the footwall rocks of mixed rocks, gneiss and pegmatite, f = 13 ~ 15, relatively stable, local instability. Ore f = 6 ~ 10, stable.
