甘肃阳山金矿床工程地质特征

针对阳山矿区工程地质特征，探讨矿山开采时可能遇到的问题，从岩石工程地质岩组的划分、构造带工程地质特征及岩矿石顶底板稳定性等方面进行分析，并结合岩石物理力学性质测试结果，认为区内岩石工程地质岩组主要有松散软弱岩类、较软岩类、较硬岩类和坚硬块状岩类。矿体在形成过程中受构造带控制及影响，岩石较破碎，岩体稳固性大多较差，易发生不良工程地质问题，分析认为矿床开采技术条件属工程地质条件复杂类型。通过对矿区不同开采条件的分析，提出了开采中可能遇到的问题及初步解决的方法和建议。

Engineering-geology Characteristics of Yangshan Gold Deposit in Gansu Province

Division of rock engineering geological petrofabric，engineering-geology characters and stability of roof and floor rocks are analyzed in order to solve the problem which would be met in discussing the engineering-geology character of Yangshan mining area and mining.The result，combining the rock physical and mechanical properties test research，shows that petrofabric in this area can be assorted into four kinds，soft and weak ones，soft ones，hard ones and adamantine ones.The orebody can be affected by the structural belt in its formation，so the rock is fragmentary，the stability of orebody is poor，and engineering geological incident might be often.And the result shows that mining conditions in this area is complex.Problems that might exist during mining process and the solutions are put forward by analyzing the mining area in different conditions.
