摘要
基于模型试验的相似理论,根据综合机械化放顶煤采空区的特点建造了三维模型。在U型和E型两种通风方式下,对比研究了综放开采采空区流场及瓦斯运移特性,得出了具有指导意义的综放开采采空区的瓦斯运移规律和合理的采空区瓦斯排放方案。
Base on the simulated theory of the model test, a three dimensional model was built according to the goaf characteristics of a fully mechanized coal caving mining face With a U type and an E type ventilation modes, a comparison study on air flow and gas migration characteristics in a fully mechanized coal caving mining face was made The gas migration law and the gas drainage plan of the fully mechanized coal caving mining face goaf have a reference to the future
