摘　　要：为了有效治理沙曲矿综采工作面采空区瓦斯隐患,依据流动相似理论和几何相似规律,在实验室建立了比例为1∶50的相似模拟通风系统及采空区模型。模型通过采用"U+L"型通风系统,得到了瓦斯在采空区内的分布特征,确定了综采工作面采空区瓦斯移动规律,该实验结果被应用于确定沙曲矿采空区瓦斯高位钻孔的位置。应用结果表明,根据模拟的结果布置的钻孔瓦斯抽采量稳定,效果显著。In order to control the gas trouble hidden in goaf of the fully mechanized working face,and to accurately locate drainage hole,a similarity simulation model was established in the laboratory with a scale of 1∶50 for the ventilation system and goaf in full-mechanized mining working face according to Flow Similarity Theory and Geometry Similitude Rule（GSR）.Using U＋L-shape ventilation system,the characteristics of index gas distribution in different space and the gas movement law in goaf were gained.Based on experimental results,the accurate location of boreholes was determined for gas drainage in goaf in Shaqu coal mine.The results show that the layouts of actual drainage boreholes are rational and effective with a result of stability gas drainage,reaching a good gas drainage effect.
