摘要: 根据几何相似定律、运动相似定律以及动力相似定律,建立采空区相似模型。模型工作面采用“J”型通风方式,利用压力测定、示踪气体、瓦斯浓度取样测试等技术手段,研究“J”型通风系统下采空区瓦斯运移分布以及采空区漏风规律。Abstract: According to the geometric similarity law, sports similarity law and dynamic similarity law, the similar model in goaf is established. J type ventilation way is used in the working face of model, using pressure measurement, the tracer gas, gas concentration sampling test and other means, the gas migration distribution and air leakage laws in goaf under J type ventilation system is studied.
