摘要
结合在综采工作面沿空留巷回采巷道进行煤巷小孔径预应力锚索加强支护的试验研究介绍了锚索支护的作用机理 ,进行了锚索支护参数设计 ,并分析了留巷的围岩变形特征。实践表明 。
The paper presents the acting mechanism and the design of support parameters of anchor by using test study of the small bore diameter prestressed force of anchor support in gob-side entry of fully mechanized caving face.On the basis of rock pressure in mine observation,the features of the deformation of surrounding are analysed.The result shows that anchor is a support way oflarge loading weight.
