Abstract: Coal mine water disaster restricts the safe and efficient development of coal resources seriously. Aiming at the typical problems of roof, floor and goaf mine water disaster at present, three aspects of mine water prevention and control in China has been carried out including water hazard assessment, water inflow prediction, water hazard early warning, and water hazard detection and control, etc. However, the intelligence of these prevention and control work is relatively low. In order to solve this problem, this paper developed a multi-data fusion remote service cloud platform for mine water disaster prevention and control combining with the integration of new concepts and technologies such as big data, digital mine, internet plus. The new mode Internet plus water disaster prevention and control service is constructed by means of interest management, flood risk analysis and evaluation, water disaster prevention and control plan design, water hazard monitoring data analysis and intelligent early warning, flood accident auxiliary decision-making and whenever and wherever possible, multi department and multi terminal collaboration. In addition, the remote service cloud platform for mine water disaster prevention and control has realized the scientific, rapid and accurate formulation of coal mine water disaster prevention scheme, improved the management level of mine water disaster prevention technology. This will provide reliable technical platform support for safe and efficient coal mining.
