Study on Chaos Characteristics of Gas Dynamic Emission Preceding Coal and Gas Outburst

摘要：

The study way of chaos characteristic of gas emission time series is put forward. The phase space of gas emission time series preceding coal and gas outburst in certain coal mine is reconstructed. Saturated embedding dimensions and correlation dimension of gas emission time series pre-outbursting are calculated by means of G-P algorithm. The largest Lyapunov exponent is calculated by means of Wolf algorithm. The results show that gas emission time series preceding coal and gas outburst is a chaos series, and a new study way for coal and gas outburst prediction is afforded.
