四川省绵竹市英雄崖重晶石矿床地质特征及开采技术条件研究

The Study on the Geological Characteristics and the Mining Technical Conditions of Yingxiongya Barite Ore, Mianzhu County, Sichuan Province

绵竹市英雄崖重晶石矿床的主要赋存层位为震旦系上统灯影组(Zbdn),矿石矿物为重晶石,矿石各项指标达到开采要求,可提供市场销售。通过对该矿床的地质特征及开采技术条件研究,认为本矿区地层复杂,构造复杂,褶皱断层较发育,岩体较破碎,自然斜坡基本稳定,工程地质条件良好。矿山为露天开采,采矿时爆破产生的溅石、震动危害较小。矿床开采技术条件复杂程度的综合类型属开采技术条件简单的矿床,开采技术条件基本适宜。

The position of Yingxiongya barite ore is the Upper Sinian Dengying Formation（Zbdn） in Mianzhu County. The ore mineral is barite. Ore indicators meet the requirements of exploitation and ore can provide for market to sale. Through the study on the geological characteristics and mining technical conditions of the deposit,there are complex of formatio, complex structure. There are many folds and faults. The rock mass is fracture. The natural slope engineering geological condition is good. The mining is open-pit mining and the mining blasting splashing stones proudce vibration damage. The complexity of integrated type of the mining technical conditions is the simple deposit mining technology conditions. The mining technical conditions is basic suitable.
