Underground Mining

Complex services consist of the following stages:

Designing

AV Group uses specialized software to design and optimize underground mining operations. All works begin with the development of an electronic passport and the uploading of parameters in the equipment modules.

Drilling

AV Group drills bore pits and wells as part of its tunneling and mining operations. The company owns the fleet of leading-edge highly efficient drilling rigs manufactured by Epiroc and Sandvik.

Charging and Blasting

AV Group uses advanced emulsion explosives of its own production - “Nitronit-PR” to perform blasting operations; these explosives are safe to handle and are notable for their high efficiency level and detonation velocity.

AV Group emulsion explosives demonstrate low sensitivity to mechanical stimuli and temperature fluctuations. They are designed, among other things, to be used in the Far North while still retaining their initial parameters. Emulsion components have a long guaranteed shelf life. The emulsion formula was created for the express purpose of being used in blasting operations in hard-to-reach places and in problematic environmental conditions.

The non-electric initiation systems, electronic detonators and small-size boosters of our own making play an instrumental role in maintaining mining parameters and minimizing destruction of the rock mass outside of the mining site boundaries, which significantly reduces losses and ore dilution in the course of rock mass excavation.  

AV Group uses a variety of modifications of modern highly efficient charging units to fulfill the requisite tasks for its clients.

Removal and Transportation of Blasted Rock Mass

AV Group performs rock loading using high productivity bucket-equipped trucks - it allows for a significant reduction of shaft sinking and tunneling cycle time.  

In order to provide rock mass transportation services, we use several modifications of underground mining vehicles with different loading capacities made by the world’s leading manufacturers.

Anchoring

AV Group uses high-efficiency Epiroc and Sandvik units ensuring that anchoring or cable bracing with different anchor types are fully mechanized.

Monolithic Lining Guniting and Erection

AV Group uses advanced equipment of the world’s leading manufacturers to carry out sprayed concrete lining as well as apply the high-grade materials selected based on the individual needs of each client. When paired with rock anchors it makes it possible for us to achieve the necessary construction speed of underground operations and ensure occupational safety.

Utility System Installation

AV Group makes arrangements to install utilities to ensure fire safety of the mining plant (mine), supply of compressed air or transportation of pulpal and liquid media, as well as builds power lines to support production facilities of the company.
