Abstract aiming at the threat of floor water outburst in large buried depth and high water pressure coal mine, this paper took Hengyuan Coal Mine as the research object, studied the disaster mechanism and multi-factor monitoring and forewarning theory, and formed the floor water disaster risk monitoring index system. Using entropy weight method and analytic hierarchy process, objective weighting and subjective weighting were carried out. On this basis, combined weighting was carried out to obtain the comprehensive weight of each water outburst factor. The research methods and results provided technical support and design reference for the construction of water disaster monitoring platform and the collection of multivariate data.
