Abstract: On the basis of research results like geological data, ground stress distribution law, rock mechanics parameter indexes and so on, analysis and forecast were done on rock burst probability of Luohe Iron Mine by adopted various kinds of rock burst criterion separately, controlled the tendency of underground rock burst. The result indicated, probability of rock burst of ash tuff, secondary quartzite, altered trachyandensite were little, but rock burst possibilities of three typical rocks of alkaline feldspathic rock , paste pyroxenite and magnetite were all above average, with the increase of depth, the level of rock burst was greater. The results provided technical support for safe and efficient production of mine.

Key words: Luohe iron ore, Criterion of rock burst, Prediction
