Abstract: Some technologies such as cloud computing, server virtualization and distributed database are studied, and the demonstration platform of emergency rescue of Yankuang is constructed, including providing basic conditions for entire system of emergency rescue private cloud platform, central database realizing the interaction of distributed database everywhere, data mining system forming the information and resource pool of early warning and forecast, forecast analysis system judging and releasing the early warning and forecast information. Practice shows that using private cloud of emergency rescue based on cloud computing distributed database to carry on data mining can forecast accidents in advance. The mine emergency rescue platform can raise the comprehensive level of emergency rescue and reduce accident loss as far as possible.
