【摘要】 本文运用系统控制理论的方法,把采场风流中瓦斯运移视为复杂空隙结构中瓦斯——空气组合气体运动系统。根据矿井通风状态变化下采场瓦斯动态涌出测定结果,按照系统输入量阶跃变化建立采场瓦斯运动系统控制模型,通过反求参数得出实测矿井通风状态变化作用下采场瓦斯涌出响应曲线。并对采场瓦斯涌出动态特性进行了初步分析。更多还原

【Abstract】 Applying system control theory, this paper takes methane mig- ralon in ventilation flow of working faces as a system of methane airmixture in complex pore medium. According to the measured results of dynamic emission of methane from working faces under the state of variable process of mine ventilation, a system control model of methane emission in working faces is set up in the light of step in put and the response curve of methane dynamic emission under the action of the state variation of mine ventilation is obtained by means of the method contrary to seek parameters. And the dynamic feature of methane emission from working faces is discussed initially.更多还原
