盂县小岩沟矿区铝土矿地质特征分析

Analyzing Bauxite Geologic Features of Xiaoyangou in Yu County

小岩沟矿区铝土矿赋存于石炭系中统本溪组中下部,奥陶系中统峰峰组侵蚀面之上,属一水硬铝石矿床。呈似层状、透镜状、窝子状。矿体厚度一般为2 m,厚度稳定。矿石主要成分为一水硬铝石,矿石自然类型为粗糙状、鲕状以及致密状。矿石品位稳定,工业品级为Ⅴ级。在论述上述小岩沟矿区地质特征的基础上,从水文地质和工程地质两方面阐述了矿床开采的技术条件。

Xiaoyangou bauxite mining area occurs in the carboniferous in the middle of Benxi group part, up middle Fengfeng group of erosion surface Ordovician system, which belongs to the monohydrate hard ore deposit with layered,lenticular and snap state. Ore body thickness generally is 2 m with thickness of stability. Main components of ore main ingredients is hard hydraulic boehmite; the natural types of roughened, oolith ore and dense. Grade is stable, industrial grade isⅤ level. In this paper, the author expounded technical conditions of deposit mining the small rock groove mining area from two aspects of hydrogeology and engineering geology, based on geological characteristics,, this paper.
