摘要
根据氧气分子运动过程中所受到的不同因素的影响,利用蒙特卡罗方法与分子运动过程相结合追踪氧气分子在矸石山中的运动轨迹,对进入矸石山内的氧气分子流的入射、传输过程进行抽样,建立基本的分子运动模型。选择在不同的环境参数下,用C语言实现对矸石山内部的分子传输的模拟计算,以入射点为中心,给出了不同半径位置的分子密度流计算结果。研究表明,应用蒙特卡罗方法研究分子传输,有助于从机理上了解在矸石山自然爆炸检测中影响其检测精度的相关因素。
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.
