青城子铅矿的矿床,主要赋存于前震旦纪白云石大理岩与云母片岩中,属于中温热液充填交代的铅锌硫化矿床(以交代为主)。按照开采条件,可以分为三类:第一类是急倾斜矿脉。倾角55°~80°。厚度1~20米不等,薄和中厚者较多,大于10米者较少,除个别矿脉的围岩和矿石较易破碎外,一般中等稳定。边
The deposit of Qingchengzi lead deposit mainly occurs in the dolomite and dolomite dolomites of the former Sinian, belonging to the lead-zinc sulphide ore deposit represented by the mid-temperature hydrothermal filling (mainly accountable). According to mining conditions, can be divided into three categories: The first category is steeply inclined veins. Inclination 55 ° ~ 80 °. Thickness of 1 to 20 meters, more thin and thick, less than 10 meters, except for a few veins of rock and ore more easily broken, the general moderately stable. side
