天宝山铅锌矿床是由东风、立山两个矽卡岩型和新兴热液充填角砾岩筒型矿床所组成。现已有近95年的开采历史。为避免资源危机,保证矿山持续生产,我们积极开展了寻找盲矿体的工作,取得了可喜的成绩,增加了矿山的储量。目前东风矿床已探清36个矿体,其中盲矿体24个,占66.6％;立山矿床已探清107个矿体,其盲矿体93个,占87％。据1981年末统计,全矿累计探明A+B+C_1+C_2级矿石总储量达数千万吨。其中矿山自己探边、摸底、探外围盲矿体所获得A+B+C_1级矿石储量达千万吨以上。(一)矿床赋存规律天宝山矿区处在
The Tianbaoshan lead-zinc deposit is composed of two skarn types of Dongfeng and Tieshan and newly formed hydrothermal filling breccia tubular deposits. Now nearly 95 years of mining history. In order to avoid the crisis of resources and ensure the continuous production of mines, we have actively carried out the work of finding blind ore bodies, made gratifying achievements and increased the reserves of mines. At present, 36 ore bodies have been explored in Dongfeng gold deposit, of which 24 are blind ore bodies, accounting for 66.6% of the total; 107 orebodies have been found in the Tieshan deposit, with 93 of them being blind ore bodies accounting for 87%. According to the statistics at the end of 1981, the total accumulated reserves of A + B + C_1 + C_2 ore reached tens of millions tons. One mine exploration edge, thoroughly, exploration outside the blind ore body obtained A + B + C_1 grade ore reserves of more than 10 million tons.
