Robotic walking module as underground mining safety device

Abstract

The authors studied the acting loads on the powered walking roof support in the preparatory mine and numerical modeling of stresses and deformations in the coal seam and host rocks in the preparatory face. The patterns of intensification of roof rocks displacements and the normative load on the workings support with increasing distance from the face are revealed. For additional safety maintenance authors designed remote control system allowing to control walking module from safe place. The purpose of the article is to develop a methodological approach to substantiate the technical parameters of a powered walking roof support to create temporary support for roof rocks near the preparatory face, preventing the risk of collapse.
