Rock Mass–Multifunction Mobile Roof Support Interaction in Mining

Journal of Mining Science Aims and scope

Abstract

The authors propose a dedicated mobile roof support for underground coal mining. Joint deformation of roof rocks and roof support is analyzed using the finite element method. The shapes and sizes of failure zones and the influence of the support on coal and host rocks are determined. The application area for the mobile roof support in underground mining is outlined, and the essentiality of the current prediction method of dynamic events during mining is substantiated. It is feasible to increase the rate of heading by means of reduction of the heading cycle duration.
