and many more. JENNMAR Engineering 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 JENNMAR Engineering in 2000 to predict and identify potential 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 to mining operations and can also be used to optimize bolting parameters based on RIR results.
JENNMAR Engineering 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-ups 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.
