Study on the dynamic response and roadways stability during mining under the disturbance of hard roof break

Kong Peng,
Liu Chang,
Yang Dechuan
et al.

Abstract: Under the condition that the working face was directly covered with hard roof, the abrupt breaking of hard roof release significant amount of energy, thus prone to triggering dynamic disasters such as roadway instability or rockburst. This paper based on the engineering background of the Xieqiao Coal Mine's 11,618 working face, a numerical simulation method was put forward to study the dynamic response of roadway under the disturbance of hard roof breaking and proposed an evaluation index IC for roadway stabil… Show more
