Technical Audit Sp zoo has been awarded a tender for the provision of design, technological and production audit services for the UK Anzherskaya-Yuzhnaya coal mine, in Russia.

The tender, which also includes the production and contract execution audit (control), involves the audit of the delivery of 120 powered roof supports for the mine.

Having been formed in December 2017, Technical Audit’s first order, in 2018, was an audit of the production of a longwall system for the Denisovskaya mine, owned by Russian coal company KOLMAR.

Since then, it has also audited the longwall system at Russian coal company Sibirskaya’s Uvalnaya mine, powered roof supports for Polish coal company LW Bogdanka, and a second longwall system audit for KOLMAR at its Inaglinskaya mine.

In 2019, the company also assisted Raspadskaya coal company with a tender process to select a supplier of the powered roof supports for its Uskovskaya mine.

Strata Worldwide says it has signed a distribution agreement with Burrell Mining International for the promotion and distribution of the Burrell CAN® and Burrell Omega Block coal mining products to the North America mining market.

These products will be added to Strata’s line of secondary roof supports and ventilation product offerings, available immediately, the company said.

The CAN is a “yieldable secondary roof support” made from a confined core of cementitious composite encased in a cylindrical steel canister, Strata said. “When installed correctly, the CAN has never failed. Its flexible design can be engineered to meet mine-specific load conditions regardless of adverse roof or floor conditions, while the smooth steel skin of the CAN also improves ventilation by reducing air resistance in the mine entry,” the company added.

Omega Blocks for ventilation are specifically formulated building block, three times the size of regular concrete blocks, but significantly lighter in weight to help reduce labour and the installation process, according to Strata. The Omega Blocks are composed of non-toxic, incombustible materials that are fire resistant and impermeable to air. The blocks are fully MSHA approved and ideal for quick construction of underground ventilation stoppings, Strata said.

Bob Weil, President & CEO of Burrell Mining International, said: “Burrell’s reputation as an industry innovator with a history of quality products and excellent customer service makes our partnership with Strata Worldwide a great strategic fit. Working together, we can provide customers throughout North America with efficient and safer secondary roof support products for the mining industry.”

Mike Berube, President and CEO at Strata Worldwide, said: “We are very excited to enter this agreement with Burrell Mining. They are a premier supplier of secondary roof support for coal mining and have an excellent reputation in the industry. The CAN will be a strong addition to Strata’s line of roof support systems and with this agreement we will offer the most complete portfolio of roof support products on the market.”

Strata Worldwide has grown from a company focused on roof supports in underground coal operations, to service mines of all types, all sizes, all commodities and all locations. It says it develops advanced safety solutions for mines all over the world.

Burrell Mining International, meanwhile, is a wholly owned subsidiary of Burrell Group Inc, a family-owned company with business interests in mining products, insurance, real estate and technology. Burrell Mining International operates three plants in the US and two in Australia.
