Abstract:

According to the impact of different factors in the process of oxygen molecular motion, this paper combines the Monte Carlo with the molecular movement to track the oxygen molecules in the coal gangue pile. The incidence and transport of the oxygen molecules in the coal gangue pile are sampled and a basic molecular motion model is established. Under different environment parameters, we use C language program to simulate and calculate the molecular transport within the coal gangue pile. The simulation uses the incident point as the center and obtains the calculation results of molecular density flow at different radius locations. Studies show that the Monte Carlo method can be used to study the molecular transport, which will help to understand the impact factors related to the detection accuracy in detecting the natural explosion of the coal gangue pile.
