根据矿体开采要求，通过岩体工程地质调查（岩体构造调查、结构面产状统计）和质量综合评价（岩石坚硬程度、完整程度、基本质量分级、工程岩体质量级别划分）对安庆铜矿1＃矿体－400m以下岩体质量进行综合评估，结果表明：岩体结构面可以分为5组，最发育结构面组优势产状与 F1断层一致；开采最佳轴线方向为28°方位，重要工程（采场、凿岩硐室等）一般垂直矿体走向布置，属于稳定性有利方向；四种主要岩体属于坚硬或较坚硬岩，完整性程度较好，工程岩体级别为III级。所得岩体质量评价结论可为矿山后期开采提供基础数据支撑。

According to mining requirements ,rock mass below -400m level of 1# orebody in Anqing Copper Mine are comprehensive evaluated through engineering geological investigation(investigation of rock mass structure ,statistic of structural plane occurrence ) and quality evaluation (rock hardness degree , integrity condition ,basic quality classification ,quality classification of engineering rock mass) .The results show that rock mass structural planes can be divided into 5 groups ,and the advantage occurrence of the most developed structural plane group is in line with F1 fault .28 ° azimuth is the best axis direction of mining ,and important project (stope ,drilling chamber ,etc .) generally is laid out along the direction vertical to the orebody strike ,which is helpful to stability .Four kinds of rock mass are hard rock or semi‐hard rock ,good integrity ,and quality of engineering rock masses belongs to III .The conclusion will provide basic data support for later mining .
