Abstract

This paper presents an application of rock engineering systems (RES) method for risk evaluation of floor water inrush (FWI) in coal mines. The newly proposed approach involves 13 effective parameters relevant to the FWI. The interaction matrix based on the RES is introduced to study the interrelations between the parameters and their effects on the whole systems. And the relative interactive intensity and dominance of each parameter were calculated. As a result, an index is presented to assess and predict the risk grade of the FWI. Comparisons to evaluate results from present method and the actual behaviour corresponding to 20 cases are made. The results of the comparisons indicate a good agreement between assessment and observation. This risk assessment methodology provides a simple but efficient tool for systematically assessing the risk of FWI in coal mine.
