The paper researches the risk evaluation methods of water inrush from coal floor based on dimensionless multi-source information fusion technique. Tak- ing Xin’an coal mine as example and based on systematic analysis of floor water inrush mechanism, six key factors affecting the water inrush from the floor of NO.21 coal seam including distribution of faults belts, distribution of the endpoints and intersection-points in faults, index of water inrush caused by faults, water pressure and watery of the Ordovician limestone aquifer and the effective aquifuge thick- ness are identified and dealt with dimensionless quantity due to the structural and hydro-geological con- ditions. The weights of each factor are determined by qualitative arrangement and quantitative trans- formation. After that, dimensionless mu
