KMS® (Keystone Mining Services) is the engineering affiliate of JENNMAR®, an established, leading manufacturer of ground control products for mining, tunneling and civil construction. KMS provides advanced ground control engineering services to JENNMAR customers along with various other industries. In addition to engineering services, KMS is also responsible for all research and development of new ground control products and systems for JENNMAR and its affiliates and is an integral part of quality control and continuous product improvement.
A key part of safety and quality is continuous improvement. KMS manages the Jennmar's Research & Development program. The Jennmar Research Center is a dedicated facility providing research and development testing and quality control of all companies products. It is fully equipped with state-of-the-art testing equipment.
KMS offers engineering services such as structural analysis, numerical modeling, 3-D modeling, and many more. KMS continually conducts research and development of many new products and improvements. Our mission is to create the highest quality products and services that make the impossible, possible. With one key factor at the forefront: safety.
The patented Roof Instability Rating (RIR) system was developed by KMS in 2000 to predict and identify potentially weak areas of roof stability across mine sections or mine property. RIR is an effective rating method that integrates several factors pertaining to entry stability with different weighting factors, geological data, and roof failure history. RIR has been successfully applied at mining operations and can also be used to optimize bolting parameters based on RIR results.
KMS has the expertise in optimizing longwall set-up and recovery entry designs based on mine-specific geological and mining conditions, mining practices, ground movement, and support characteristics of JENNMAR and JENNCHEM roof support products. Many set-up and recovery entries have been successfully designed and applied at the request of our customers, while meeting MSHA’s Technical Support requirements in avoiding roof and weighting type failures and protecting the safety of miners.
