| 摘 要： | 为了对大河边向斜内煤与瓦斯突出进行区域预测与防治;根据向斜内煤层突出的特点,地质构造特征,地应力作用,煤层厚度及产状变化、煤层透气性的实测数据分析,探讨了向斜南北部及中部煤层突出的差异,研究了大河边向斜煤层突出机理.结果表明高瓦斯和封闭性好的地质条件是瓦斯突出的物质基础,压性和压扭构造等地质构造的发育及地应力作用是导致突出的重要因素,在向斜中部C409,C407,C406突出危险性最大,在向斜北部C409,C601突出危险性最大,在南部煤层突出危险性小;该成果对大河边向斜内进行煤与瓦斯突出区域预测与防治具有指导意义.

| Abstract: | In order to predict and control coal and gas outburst in Dahebian syncline,we analyzed the geological structure,ground stress,thickness of coal seams,appearance of coal seams,and air permeability of coal seams,discussed the difference in outburst characteristic between south part,middle part,and north part of the syncline,and studied the mechanism of coal and gas outburst in Dahebian syncline.The result shows that 1) high gas content and good sealing structure are the substance base for gas outburst,2) comp... |
