| Abstract: | The instability and its harm of opencast bench above the vacant area's roof left by underground mining in Zijinshan Gold Mine is analyzed in the view of engineering structure and stability of rock. The reason and the rule of opencast bench instability is described, and the measure of prevention and control is given. The effective ways of prevention from instability of opencast bench are check and mensuration of void and concealed void, and control of vacant roof stability, and determination of minimum safe thickness of the vacant roof. |
