At Keystone Mining Services, we understand that tunnel design and support must be accurate and cost effective. This type of support must be adaptive to the stress environment and compatible with the equipment utilized by the contractor. Our ability to conduct detailed stress analyses, field observations, and stratascope analyses combined with years of experience ensures our customers a successful and cost effective solution to tunnel design and ground control. We also provide analyses to develop supplemental ground support systems to solve unexpected ground control problems or rehabilitate existing tunnels.

Rock bolts and strand anchors, for both temporary and permanent use, are produced from job tested and best-suited product materials. Strategically located fabricating operations are located in the US and Australia for prompt reliable customer response.
