The mechanism of decrease in bearing capacity and performance evaluation of the yielding bolt in coal mine
Abstract With the increase of the coal mining depth, the surrounding rock shows characteristics of high stress and large deformation. However, the traditional bolt could not adapt to this surrounding rock environment and become invalid due to low elongation. In order to solve the problem, the new ty...
