摘要
Abstract
The serum diffusion radius and the roof pressure are calculated in retaining entry through the stress distribution analysis of roadside packing body.Then,the deformation and load characteristics of filling body and the deformation characteristics of roadway surrounding rock are analysised by the experimental observations,the parameter analysis and the bearing characteristics of roadside packing body.The results showed that the serum diffusion radius is approximately 5 m,the trend of load in roadside packing body can be divided into 3 stages as different distance with working face,the activity degree of roof and floor is related to the distance with working face.Furthermore,it lead to different displacement from roof to floor.关键词
