Abstract
As mining progresses to deeper reserves, the accompanying high stress and rockburst hazards increase and cannot be prevented. Therefore, the position of rockburst, hazard level, as well as how much energy released need to have quantitative analysis, which can provide a safe and effective guideline for mining operation. In this paper, take the Linglong Gold Mine as background, the relationship of surrounding rockmass and rock impact energy index could be derived from simulating the ground stress environment in lab. Based on above equation, FLAC 3D is used for simulating the mining operation of Linglong Gold Mine in regard of the size of rock impact energy in current excavation stress condition, which breakdown the limitation of previous method of getting the indicator of rock burst tendency evaluation from uniaxial compressive full stress-strain curve, and provide the reference for safe mining operation.
