Comprehensive prediction of rockburst tendency based on the method of variation coefficient-mutation series in Huanaote Mining Aera

In order to predict the rockburst tendency of the mining area accurately, five indexes of rock uniaxial compressive strength, impact energy index, elastic strain energy index, ground stress index and RQD value are selected to obtain the single index evaluation results of rockburst tendency through the ground stress measurement, indoor rock mechanics test, and rock joint and fissure investigation with Sirovision. At the same time, the method of variation coefficient-mutation series is introduced to establish a rockburst multi-index evaluation system, and the mutation series value is compared and analyzed with the actual rockburst level. The analysis results show that the mutation series value is positively correlated with the actual rockburst level, and the rockburst tendency can be predicted. The research results show that the method of variation confficient-Indians huts mutation series has good practicability in Huanaote Mining Area of Baiyinhubu Gold Mine and can be used as a follow-up rockburst prediction basis in the mine.
