Designing the Lining of Special Galleries with Consideration of Imposed Loads

Abstract

The lining, in addition to securing mine galleries against the pressure of deforming rock mass, often acts as a supporting structure for the gallery equipment. In order to implement the technological process in an underground mine, special galleries are also created. Apart from significant cross-section dimensions, these special galleries are characterised by additional lining loads resulting from the equipment suspended on it. The problem under consideration was presented on the example of chamber workings used as loading stations. The implementation of transportation tasks in these workings required the construction of more suspended railway routes. To solve this task, numerical methods were used, taking into account the load from the rock mass, as well as the static and dynamic load from the installed and moving transport equipment. Additionally, this paper presents the procedural principles for designing special purpose galleries.
