摘　　要：针对劳服铁矿工程地质条件、水文地质条件、岩体力学特性及开采技术条件等,应用岩体工程地质力学方法进行了工程地质划分、节理裂隙统计和岩体结构分类。同时应用《工程岩体分级标准,GB50218-94》分级方法对劳服铁矿岩体质量进行了系统全面的分类和评价,其评价结果为矿区顶板岩层片麻岩和底板花岗质混合岩岩体质量级别为III级至II级,底板花岗质混合岩岩体质量级别为II级至I级。According to the engineering geological conditions,hydrological and geological conditions,rock mass mechanical characteristics and mining condition of the iron ore,by using the method of geological mechanics of rock engineering,the classify of engineering geological division,joint statistics and rock mass structure were conducted.At the same time,applying the classification method in ＂standard for engineering classification of rock masses,GB50218-94 ＂,the rock mass quality of the iron ore was systematically and comprechensively classified and evaluated,the evaluation result showed that the mass quality level of roof rock gneiss and granitic migmatite floor rock were III to II,and the quality class of granite rock bottom mixture was II to I.
