The method of drilling bits is a common method to predict the rockburst. This method establishes a quantitative relationship between the drilling cutting quantity and the stress in coal body. But in the process of mining, the common early warning indicator often has some disadvantages such as limitation and hysteretic nature due to some limiting factors. Taking the method of drilling bits as the theoretical basis and the No.3302 coalface of Xingcun coal mine as the engineering background, this paper proposes a new warning method and the new early warning indicator to make up for the limitations and hysteretic nature. The new early warning indicator is obtained by comparing the drilling cutting quantity before and after mining in the depth range of coal bodies with impact risk. Based on the variation trend of drilling cutting quantity and drilling rate warning indicator, the new real-time warning method is proposed. This method can be used to analyze the danger of rockburst in potential danger areas, which could be valuable in the design of rockburst resistant measures in deep buried construction.
