| 摘 要： | 煤与瓦斯突出是煤矿井下严重灾害之一,而抛出物是灾害发生的直接作用者。本文应用空气动力学原理,建立了抛出物在巷道空间运动的数学模型,在IBMPC计算机上采用BASIC语言进行了模拟。结果表明,以两相流体假说为基础的抛出物流体系较以瓦斯为主导的假说更为接近实际;突出发生在上山、水平和下山巷道中,抛出物的分选性依次降低。

| Abstract: | Coal-gas outburst is one of the major disasters in coal mine, however, the thrown body is direct actor. The paper builds the mathematical model of thrown body movement in the roadway with aerodyaamics and simulates its course with basic language in IBM-PC. The results of simulation based on the hypothsis of two-phase fluid are more conformable to the reality than that of outburst mechanism hypothsis with gas as the leading factor. The classificatin of thrown body is obvious in the raise, next in the level and not obvious. in the winze. |
