The water outburst spread algorithm can obtain the water flow diffusion path and submerged range after mine water outburst in real time, which is of great significance to escape path planning and emergency rescue. Aiming at the problems of incomplete description of submergence process and separation of up-down spread in the traditional one-way water outburst model, based on the idea of graph theory, this paper abstracted the underground roadway entity into an undirected graph network, and used slope and elevation as comprehensive weight factors. The recursive and backtracking mechanisms were used to decompose the complex water flow process. And the downward recursive algorithm of water flow, the upward termination algorithm of water flow and the bidirectional spread recursive algorithm of water flow coupling the two were proposed. Taking Zhangshuanglou Coal Mine in Xuzhou as an example, the bidirectional spread recursive algorithm was verified. The results showed that the algorithm could accurately and effectively complete the unconstrained flow and process deduction of water flow at any position in the roadway, and obtain the water depth and flow data at any position and any time in the mine. It realized the dynamic visualization and range prediction of the spread process, and provided technical support for the emergency response of water disaster and the formulation of rescue plan.
