摘　　要：岩石工程界普遍重视工程岩体的分类。煤炭井工开采作为岩石地下工程领域的特殊工程行业,会经常性面对开采中围岩的稳定性评判以及支护设计工作。为总结工程经验、发挥已有的设计与施工经验、进行行业技术交流,工程岩体分类已成为国际趋势。工程岩体的RMR分类方案是国际岩石工程界普遍使用的岩石分类方法。利用该方法对大同矿区8个生产矿井的石炭二叠系岩层岩体进行了分类,分类结果在煤矿巷道围岩支护设计中起到了指导作用。The engineering classification of rock mass is generally valued in rock engineering field.As a special engineering kind in the field of rock underground engineering,coal underground mining often faces the stability evaluation of surrounding rock and support design for surrounding rock.The engineering rock mass classification has become an international trend for the purpose of to summarize the engineering experience,give the experience full play to the existing design and construction,and carry out technical exchanges in the industry.RMR classification scheme of engineering rock mass is the rock classification method widely used in international rock engineering field.Using this method,the Permo Carboniferous strata and rocks of 8 production mines are classified,and the The classification results had been playing a guiding role in the design of surrounding rock support of coal mine roadway.
