凡口铅锌矿深部开拓方案的确定

Decision of the Construction of Zine-lead Deep Deposits Extraction in Wankou Mine

本文根据凡口铅锌矿深部矿体赋存特点和开采技术条件，对四种可能的开拓方案：主井延深、主斜坡道汽车运输、盲主井和胶带输送机斜井运输方案进行了分析、比较，确定了主井延深方案为最佳开拓方案。

The basing on the character of the mineral deposits and conditions of the extraction technologies. We studied and Comparated the four projects on extraction as follows:the major shaft deepening, Vehicle haulage on the important acclive baulageway,Unlighting shaft and band conveyer. After this, we bas conuled that the major shaft depening is the best one.
