Abstract: Starting from the highly dynamic characteristic environment of mine ventilation safety, the paper analyzes five kinds of data types which are considered to show important dynamic characteristics in coal mine ventilation safety. It is pointed out that ventilation and gas are the most obvious dynamic characteristics and the most important factors influencing the possible accidents or disasters. The dynamic data related to the safety of coal mine ventilation are sorted out from the three types of mine ventilation system, working face and heading face. It is pointed that the safe dynamic data and materials have their time tags and location attributes, all data with time tags and location attributes should have the ability to record the information change process and summarize the ventilation safety dynamic data integration platform design principles. Take a coal mine in Yangquan as an example, combined with daily ventilation safety management, the basic data types and basic framework of dynamic data platform for coal mine ventilation safety are established.
