摘要

Using research results on physical properties of primary coal and rock mass, in this paper, response characteristic function y(t), amplitude frequency characteristic H(ω)and phase-frequency characteristic ψ(ω) were used to describe dynamic response of stress impulse signal. At the same time, with the help of computer simulation analogue technique, applying these characteristic parameters to research the rock-burst forecasting,this paper deduced response characteristic function model. This function model is valuable for rockburst tendency test. According to these researches, develops monitoring recording system to acquire rockburst precursor signals. This system can monitor stress impulse signal dynamically and continuously. By applying the forecast information systems can forecast rockburst successfully.
