东天山东戈壁超大型钼矿床水文地质概况及地质工程评价

Hydrogeology survey and geological engineering evaluation of superlarge molybdenum deposits in the east dongtianshan gobi

确定矿床充水的主要含水层及其主要充水因素,指出矿区供水水源地方向;对矿区主要岩石及矿体顶底板岩石进行物理力学测试,评价矿体围岩及其顶、底板岩石的工程地质条件,查明构造断裂带、软弱夹层对矿床开采的影响;对露天采场边坡的稳定性做简要定性评价;划分矿床水文地质、工程地质及环境地质勘查类型,为矿床经济技术评价及未来矿山建设可行性设计、总体规划提供依据。

The paper determined the main water filling aquifer and water filling factors of the deposit,and pointed out the direction of the mining area water supply source;carried out mechanical test for the main rock and orebody roof and floor rock,evaluated the engineering geological conditions of host rocks of the ore bodies and top and floor rock and identified the effect of structural fracture belt and soft interlayer on the ore mining;slope stability of open pit was briefly evaluated;deposit hydrogeology,engineering geology and environmental geology exploration were divided into several types,which can provide the basis for economical and technkal evaluation of ore deposits,and feasibility and general plan of mine construction in the future.
