| 摘 要： | 冬瓜山铜矿床是我国首例埋藏深度超过千米的金属矿床．目前正在进行有岩爆倾向深埋矿床的开采技术研究．分析了冬瓜山7种典型岩石的弹性能量指标WET、脆性系数R、冲击能量指标WCF和试块储存的最大应变能Es等4项指标．认为这7种岩石中有2种具有中等岩爆倾向，2种具有微弱岩爆倾向．还有3种不具有岩爆倾向．

| Abstract: | Dongguashan Copper Deposit is the first metalliferous deposit lying below surface over lion in China. Research on mining technology of deep deposit prone to rockburst is carried out. Four factors of elastic energy index We, brittleness index R, shock energy index WCF and strain energy stored in specimen a of seven typical types of rock at Dongguashan Deposit are studied. It is considered that two types of the above rocks are of medium prone to rockburst, two have weak proneness and the other three have no proneness to burst. |
