The primary focus of this industry is to undertake the comprehensive process associated with the extraction, transportation, and processing of various types of mined materials, including coal, ores, and other raw materials. This industry plays a crucial role in providing raw materials for many sectors, such as energy, metallurgy, construction, and many others.

One typical example of our activities in this industry is the supply of Longwall systems for underground mining. Longwall is an advanced mining system that enables efficient and productive extraction of coal and other minerals from beneath the surface.

In addition to underground mining, our industry also specializes in the delivery of transportation systems for surface mining. These systems are designed to facilitate the transportation of mined material from mining sites to processing or storage locations. This includes conveyor belts, conveyors, loaders, and other equipment, which are key components of the entire mining and processing process.

The company has extensive experience and technical expertise in this industry, allowing us to provide top-notch and reliable systems for mining, transportation, and processing of mined materials to clients worldwide. Our goal is to help our customers achieve maximum efficiency, productivity, and safety in their mining operations.
