driving underground workings:

• driving stone galleries (stone drifts),,
• driving coal and coal/rock galleries (inclined drifts, rise galleries, ventilating roads),
• driving rooms (technological recesses, cellars for mechanical devices installation).

relining of workings:

• relining of workings with flitching and roof ripping,
• lining mounting in the existing neat lines of a working,
• lining reinforcement with steel or timber elements,
• applying reinforcing cement coatings.

application of winning haulage methods and material supply by suspended railways and self-dumping containers.

design and installation of “ready to use” cooling systems of underground workings of power up to 15 mw:

• installation design for a given geological conditions based on the existing diagram of a potential ventilation network,
• supply of devices and materials necessary for design development based on the order,
• installation of refrigerating units, pipe networks, air coolers and evaporative coolers,
• preparation of workings for the installation of refrigerating units and evaporative coolers.
