摘要

SAS statistical analysis software was used to test the randomness of electromagnetic radiation (EMR) observed during the ';1.12 rock burst'; of the number 237 working face in the Nanshan coal mine. An auto-regressive-moving-average (ARMA) model was fitted to the EMR data and used to forecast twelve observations into the future. The results show that the rock burst EMR data are non-white noise, stationary and can be fitted with an AR(3) model. Comparing the model EMR values to the real data, the similarity degree is about 66%. An ARMA model can use data preceding an event to describe changes in the EMR trends quantitatively.
