Geological analysis on relationship between structural coal characteristics and carbon dioxide outburst

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.
