The utility model relates to the technical field of mine safety, in particular to a simulation training and practicing system for mine workers and draegermen, which enables people to have an immersed on-site sense, can achieve human-computer interaction and interaction and can evaluate the practicing results. In order to achieve the purposes, the analog simulation training and practicing system for a mine gas disaster comprises a main-control computer, a three-dimensional circular-screen projection subsystem, a human-computer interaction subsystem, a synchronous interaction subsystem, a human behavior detection subsystem and a human physiological monitoring subsystem, wherein the three-dimensional projection subsystem, the human-computer interaction subsystem, the synchronous interaction subsystem, the human behavior detection subsystem and the human physiological monitoring subsystem are electrically connected with the main-control computer respectively.
