Abstract: There are three steeply inclined and extremely thin ore bodies sub-parallel to each other in Erdaogou Gold Mine, which can be caved by the methods of resuing stoping and short-hole shrinkage. As the mining goes deeper, rockburst occurs more frequently, which has seriously affected the mining production already. According to the investigation and analysis of rockburst-prone stopes, three major necessary conditions leading to rockburst were summarized, namely high stress in the rock mass, high strain energy accumulated and sudden energy release. It was also revealed that the primary cause for high stress was the additional force caused by the wedge of hanging wall. Furthermore, the scheme of stope rockburst control by distressing was proposed and put into experiment, and the experimental results show that distressing by caving has a remarkable effect on rockburst control for this kind of rockburst-prone stopes for normal caving.
