我坑矿体赋存于上昆阳群三家厂组中间的白云岩与板岩互层中,呈浸染交代似层状、透镜状,(尸专)中温热液矿床。矿体南北走向长980米,东倾60～80°,局部90°,垂深675米。矿体厚2～15～40米,f=6～8中(禾文),受断层控制而分枝、复合再现显著。上盘为白云岩,f=6～8中(禾文)。下盘为长石、石英、板岩互层,f=5～6中(禾文)或不(禾文),节理、裂隙发育。在矿体和下盘围岩中掘进必须及时支护,否则(?)冒落。矿石类型主要是硫化矿(黄铜矿,斑铜矿),其次是氧化矿(孔雀石等),容重2.65吨/米~3,松散系数1.6。
I pit deposit occurs in the upper Kunyang group of three plants in the middle of the dolomite and slate interbed, was disseminated like stratified, lenticular, (corpse) mesothermal hydrothermal deposit. The north-south ore body is 980 meters long, with an eastward inclination of 60-80 °, a partial area of 90 ° and a depth of 675 meters. Ore body thickness 2 ~ 15 ~ 40 meters, f = 6 ~ 8 (Wo text), controlled by the fault of the branch, composite reproduction significantly. The plate is dolomite, f = 6 ~ 8 (Wo text). Under the plate for the feldspar, quartz, slate interbed, f = 5 ~ 6 (Wo text) or not (Wo text), joints, fissures. Tunneling in the ore body and the surrounding rock must be supported in time, otherwise (?) Ore types are mainly sulfide ore (chalcopyrite, bornite), followed by oxide ore (malachite, etc.), bulk density of 2.65 tons / m ~ 3, the loose coefficient of 1.6.
