Abstract

Separation water is a commonly-seen water hazard in China coalmines. This article, built on case studies of disasters caused by separation water, analyzes the key influencing factors in the formation of separation and the water hazard, as well as the features and causes of explosive, delayed explosive, and intermittent separation water burst. The article takes as an example of one accident caused by roof bed separation water burst in the 745 working face of Haizi Coalmine. The study has a particular interest in separation water burst accompanied by rock burst when mining under thick-hard igneous rock. The results are of reference to countries with similar mining conditions and researches on separation water burst and hazard control in coalmines.
