4 The 29th International Conference on Ground Control in Mining In total, 10 various support systems are applied in the model and the tunnel stability for each system is evaluated. These applied support systems are shown in Table 2. Table 2 The studied Support systems and their indices
Mine and Tunnel Roof Support Systems. Camber has developed procedures and products for specialized support of caved areas and unsupported roof. The Sliding Arch Canopy System provides support and a safe work environment as you clean up roof falls or advance through broken strata. Once in place they can be cushioned using Camber Geotek Bags ...
This research recommends a support system for a mining tunnel roadway in the E1 longwall panel in the Parvade 1 underground coal mine in Iran. The FEM was used to perform stability analysis and to suggest a support system. The tunnel was modeled with Phase2 software before imposing a support system.
Underground. Tensar mining systems offer a wide range of cost-saving solutions to meet the needs and objectives of mining operations. Among the proven applications are roof and rib control, and longwall shield recovery screens. Tensar mining geogrid, teamed with Minex™ Rock Mesh, provides effective roof and rib control for soft minerals as ...
Mine Support Products (MSP) is a manufacturer of underground support systems for the mining industry. The company has been developing and manufacturing products for deep-level mining clients for the last two decades, and is co-owned by heavy engineering …
Stability level of tunnels that exist in an underground mine has a great influence on the safety, production and economic performance of the mine. Ensuring of stability for soft-rock tunnels is an important task for deep coal mines located in high in situ stress conditions. The aim of this study is to investigate the effect of tunnel shape and support pattern on the deformation, failure zone ...
To date, there are few underground communication and tracking systems available for tunnel projects that support OSHA (Occupational Safety and Health Administration) compliance. After the 2006 Sago Mine disaster, research and development was performed to improve communication systems for the underground environment.

Published inUnderground Support Systems. Edited by J. Udd. (Montreal; Canadian Institute of Mining and Metallurgy). Special Volume 35, 1987, pages 1-6. Support in Hard rock Underground Mines 2 Introduction Rock support is the term widely used to describe the procedures and materials used to
A mine tunnel support system in accordance with one aspect of the invention comprises at least, three spaced, interconnected support sections, each section including at least one bearing member which, when the section is in a first, loaded state, bears against the roof of the tunnel and, when the section is in a second, released state, is moved ...
The basic functions of a tunnel support system are to keep the tunnel stable and to make the opening usable. The specific purposes of support systems, however, depend greatly on the purposes of the tunnel. Traditionally, tunnel supports have been classified into two groups, temporary and
