    Abstract
  • In view of problem of strong subjective element in determination of index weight of safety level of production logistics of coal mine, entropy weight method was used to determine index weight of safety level, system dynamics approach was applied for dynamic simulation of factors affecting safety level, and incidences of various factors affecting safety level of production logistics of coal mine were contrasted and analyzed. The simulation results show that degree of mechanization and roadway environment have the maximum practical activity ratio, therefore, improve degree of mechanization and strengthen the safety level of the roadway environment are the keys to improve safety level of production logistics of coal mine.
