摘　　要：根据窑街三矿皮带斜井矿井地质工作实践 ,研究了该斜井构造煤结构特征 ,并阐述了其与二氧化碳突出机理的关系。地质构造、煤体结构及煤厚变化是二氧化碳突出的三项重要因素和必要条件。Based on experiences of geological work in the 3 rd Mine of Yaojie Mining Administration,the characteristics of structural coal in the mine are analyzed.The relationships between coal characteristics and mechanics of carbon dioxide outburst.The results show that the most important control factors include geological structures,coal texture and coal thickness variations.The forecast for outburst potential areas can be conducted according to distribution regularities and thickness variations of structural coal.
