ANALYSIS ON ENERGY DISTRIBUTION AND PREDICTION OF ROCK BURST DURING DEEP MINING EXCAVATION IN LINGLONG GOLD MINE
|
Abstract:
The mining depth in Linglong gold mine is more than 500 m and will exceed 1 000 m in the future. Rock bursts will be a serious problem for the mine during deep mining excavation. Based on the results of systematical rock mechanics experiments and numerical modeling analysis, the distribution status of energy in surrounding rock mass and possibility of rock burst during deep mining excavation in Linglong gold mine are analyzed, using various prediction criteria of rock burst. The methods for protection of rock burst are also provided.
