中文摘要:

针对冬瓜山铜矿深部开采,从地质特征与采矿方法、工程布置和回采工艺之间的关系论证合理的采矿设计;针对开采中揭露的岩体地压现象,分析采区构造型岩体破坏和应力型岩体破坏特征。研究表明,在开采设计中地质因素与采矿的合理关系是岩体稳固性控制的有效措施;顶板主要为构造型破坏而底板主要为应力型破坏,较大规模构造型破坏呈局部性特征,采取针对性支护方式可有效控制;矿柱是危险性地震和岩爆的区域,需快速回采和及时充填。研究结果对该矿安全生产起到了良好效果。

英文摘要:

For the deep mining of Dongguashan Copper Mine,the relationships between the geologic characteristics and the mining method,layout of mining works and process of extraction were analyzed in terms of stress state and rock stability control,on that basis of these,the rationality of mining design was demonstrated.According to the phenomena of rock failure in the mining area,the two kinds of rock failure caused by geologic structure and ground stress were researched.The results showed that the reasonable relationship between geologic factors and mining is an effective measure of the rock stability control;rock failure caused by rock structure is basically in the roof,rock failure by stress is mainly in the floor;large-size rock failure caused by structure locally occurs and can be effectively controlled by pertinent supports;the pillars are locations where hazardous seismicities and rock bursts occur;therefore,the fast stoping and backfill are very important.The results of research have played a good role in production safety for the mine.
