Strata Mine Services Seal receives final MSHA approval
(MSHA Approval Number: 120M – 01.0)
On September 17th 2008, the Stratacrete Plug Seal, designed and engineered by Strata Mine Services, is officially the first ventilation seal to meet the requirements of the new MSHA Final Rule (30 CFR Part 75) and successfully gain approval.
The MSHA Final Rule, effective April 18th 2008, specifies new requirements for seal designs, construction, maintenance and repair. It addresses the required strength of the seals, levels of overpressure and the monitoring and control of the environment behind the seals. According to the Final Rule, in areas where the atmosphere behind the seal is not inert, the seals are to withstand repeated 4-second explosions of 120psi. MSHA has ruled that after October 18th 2008, only seals with final approval will be cleared for installation.
The Stratacrete Plug Seal is constructed with formwalls set at a specific distance apart and then remotely filled with a specially blended concrete mix called StrataCrete. StrataCrete can be mixed and pumped from remote underground areas over distances of 3,000 feet, or from the surface over distances of 5,000 feet. The thickness of the seal is dependent on the height and width of the entry. The Plug Seal is approved for heights ranging from 2.5ft to 16ft and for widths from 16ft to 40ft.
“We are pleased not only to have gained MSHA Approval on our seals, but also to be the first company to do so. Strata Mine Services is currently working at obtaining approval for additional seals. One in particular is our popular pre-stressed seal that we believe will be a significant benefit for the US Coal Mining Industry,” says Rory Paton-Ash, the President and CEO of Strata Mine Services.
Having received MSHA approval under the 2006 Mine Safety Emergency Temporary Standard (ETS) on the Plug Seal, installation of these products has already commenced in a number of mines.
Strata Mine Services Inc. is based in St. Clairesville Ohio and provides turnkey underground construction services nationwide for the US Coal Mining Industry. The company specializes in the installation of seals and overcasts, concrete placement, cavity or void filling, rock consolidation and Gunite application.
