Influence of soft rock on stress distribution in surrounding rock of roadway and bolt support control [United States] S. S. Peng L. B. The presence of soft rock and bedding in the roof of Ge greatly affects the stress distribution in the surrounding rock of underground roadway. Special attention should be paid to the design of support. In this paper, the influence of various factors on the stress distribution in surrounding rock of rectangular roadway is discussed by means of numerical analysis and dimensional theory. Through the bolt supporting the front and rear stress points ...
