摘　　要：对煤壁前方卸压带、集中应力带应力分布及变形情况进行剖析,并利用极限平衡方程确定卸压带瓦斯抽放钻孔孔深。为平沟煤矿0908综采工作面卸压带瓦斯抽放设计提供了科学依据,确保了工作面的安全生产。Dissects the distribution of stress and deformation in the stress-relaxed and stress-concentrated areas in front of the coal-face,and determines the borehole depth for gas drainage from stress-relaxed area by the limiting balance equation.The study provides a scientific basis for the gas drainage design from full-mechanized coal-face 0908 in Ping gou mine,which makes sure the safe production of working face.
