Scientists from the Research Center for Applied Geomechanics and Convergent Mining Technologies at the NUST MISIS Mining College have proposed a new solution for the key mining challenges associated with safety, efficiency and environmental friendliness - creating sustainable 'honeycomb' mine structures underground. 

This technology is a part of the innovative nature-like (convergent) and functional subsoil development, which allows a major reduction in the volume of waste rock storage on the Earth's surface, and enables a scale-down in the rate of industrial accidents and injuries of mine personnel. Up to 400 billion tons of waste rock - often more than the volume of extracted minerals - is taken from the subsoil to be stored on the earth's surface annually.

It avoids large-scale blasting and enables ore to be extracted from vertical 'pipes' drilled underground. The created system of drill holes is a very stable mine structure, similar to the structure of a porous human bone bearing load. The system allows reducing the loss of minerals left in pillars during mining from 50-60 percent to 15-25 percent. It is also convenient to store mining waste in these mined-out voids without lifting it to the surface.

This method of mining significantly reduces effective stresses in rock mass, minimising the risk of rockburst and unpredictable strains and displacements in rocks. As a result, the number of accidents in mines can be reduced. Thanks to the new technology the large-scale waste rock dumps formed during development of the lithosphere may become a thing of the past. The mines applying this technology will reduce waste storage on the surface by 100 percent.

The project, supported by a grant from the Russian Science Foundation, is currently at the basic research stage. Lab tests of physical models of any complexity mine structures are made with 3D modeling methods, creating and validating standard versions of other convergent geotechnologies for underground mining of mineral deposits of any geological types.

Axora launches global challenge for digital technology

Axora, the industrial B2B digital solutions marketplace, has launched 'The Axora Cost-Saving Technology Challenge' to discover game changing innovations

Axora is launching the world’s first international competition to discover new cost-saving digital technology for industrial companies, which can produce rapid benefits within a year.

Axora

The Metals & Mining and Oil & Gas sectors have recently experienced budget cuts of 20% on average, driven by a variety of factors including the global pandemic, slump in demand and price wars. The Axora Cost-Saving Technology Challenge aims to transform these industries by discovering innovative, digital solutions that reduce cost fast and pay for themselves, whilst achieving the same or improved productivity, health and safety and sustainability standards.

Digital Transformation

“While digital solutions can help to get work done quicker and more cost-effectively, they typically require a three-year ROI, and if there’s no flexibility in the budget, a full budget planning cycle is needed to get things moving”, said Dr. Nick Mayhew, Chief Commercial Officer, Axora.

“Yet, extra financial cost is often incurred in delaying digital projects, so customers have asked us to highlight solutions that can have an ‘in year payback’ whereby the cost spent on the solution and deployment will be more than recovered within the budget year - this accelerates the timeline and drives positive business impact, quickly.”

The Axora Cost-Saving Technology Challenge

Axora is keen to learn of any digital cost-saving innovation which: meets the 12-month payback timeframe; can be deployed in any part of the value chain including upstream, downstream or midstream oil and gas, metals processing or mining; and is ready for market. The Axora Cost-Saving Technology Challenge is open to entrepreneurs, start-ups, academics and sector leaders across the world. The competition will be judged by a panel of leading industry experts.

“We’re passionate about supporting our industries and customers through all forms of digital transformation and the cost-saving solutions we are searching for could also provide a lifeline to many mining and metals and oil and gas companies in the current economic climate,” added Dr. Mayhew.

Improving productivity, safety and sustainability

Up to ten finalists will be chosen to pitch their solutions at a digital pitch day later this year, after which Axora will validate the ROI models and vet the solutions. The winner will receive the ‘Axora Market Accelerator’ sales and marketing package worth £10,000. This includes a two-hour workshop, promotion through Axora’s thought leadership content and inclusion into its digital demand engines, providing the opportunity for the winning solution to benefit thousands of industrial companies. Entries are open until May 31. Full details of the competition including terms and conditions can be found here.
