我矿为黄铁矿型铜矿床,呈不规则脉状产出,共由19条铜矿体及一条单硫矿体组成。1~#铜矿体占总矿石量的92%。在第一中段,矿体厚度为2~20米(平均5.05米),倾角80~85°。矿石有两种类型:一为浸染状矿石,稳固性较差,f=6~8;再是致密块状矿石,稳固性较好,f=8~12。矿体上盘围岩为火山碎屑岩及斜长花岗岩,稳固性较好,而下盘是稳固性欠佳的蚀变花岗岩。特别是矿体直接上下盘为千枚岩或片理化强蚀变花岗岩时,稳定性又较差。
My mine is a pyrite-type copper deposit with irregular vein-like output, consisting of 19 copper ore bodies and a single sulfur ore body. 1 ~ # copper ore body accounts for 92% of the total amount of ore. In the first middle section, the thickness of the orebody is 2 to 20 meters (average 5.05 meters) and the inclination angle is 80 to 85 degrees. There are two types of ore: one for the disseminated ore, poor stability, f = 6 ~ 8; then dense lump ore, better stability, f = 8 ~ 12. Surrounding rocks of the orebodies are volcanic clastic rocks and plagiogranite, which have good stability, while the lower plate is an unstable granitic rock. In particular, the ore body directly up and down the plate for the phyllite or piece of physical alteration granite, the stability is poor.
