CHARACTERISTICS OF DEFORMATION AND DAMAGE OF SURROUNDING ROCK ALONG THE TOP ROADWAY IN THE WORKING FACE OF AN ISOLATED ISLAND AND ITS EVOLUTION LAW

Abstract This study investigates the deformation and damage characteristics of the surrounding rock along the top return mining roadway of an isolated island working face at different stages and reveals its damage mechanism and evolution law.Utilizing a mine in Yangquan City, Shanxi Province, China, as the engineering background, this research empl

Some compaction states cause changes in soil structure, resulting in increased soil density and soil resistance to penetration (RP).The objective of this study was: a) to analyze the variability Custom Cushion of the studied attributes of the plant and the soil; b) define the linear and spatial correlations between plant and soil attributes; and c)
