Pattern of gas explosion induced coal dust explosion
Abstract：Application of continuous phase and particle phase method of calculation,the propagation of gas explosion induced deposition of coal dust explosion was simulated,and the pattern and the differences were studied.According to the simulation results,the pattern of gas explosion induced coal dust explosion were defined as self-ignite deposited coal dust explosion and premixed flame,depending on the explosion of coal dust cloud ignition mechanism plays a dominant role in the process.Further analysis shows that significant changes of shock wave and flame propagation,small-scale induction length of the flame zone and change of temperature distribution of roadway cross-section are affected by different pattern.
