INDUSTRIAL AIR CONDITIONING

Working conditions in underground mines have their difficult specificity in comparison with working conditions on the surface.

Apart from the technical hazards resulting from technological processes, there are also natural hazards related to the area around the excavations (water, gas, gas and rock outbursts, gas and dust explosions, rockbursts, climatic hazards).

The deeper the deposits of raw materials, the higher the temperature of the surrounding rocks and the more difficult the working conditions.

Currently exploited copper deposits in Poland from the depth of 1300 m, coal from levels 850 to 1030 and potassium salts in Belarus from 700 to 900 m require designing a ventilation and air conditioning system on the basis of local conditions and the existing and planned cross-sections of mine workings, the temperature of the surrounding rocks, the speed of air flow, the number and size of machines and people working at a given level and in a given area, as well as bearing in mind the safety and comfort of crews working underground, the size of temperatures occurring locally at a given humidity.

Polish mining law obliges the employers who employ workers underground to ensure working temperature does not exceed 28 degrees Celsius, or if it is not possible, to reduce the working time of the crew to 6 hours, and a temperature rise to 33 degrees Celsius is considered as working in emergency conditions.

Ensuring stable microclimate parameters in time by means of ventilation and air-conditioning of pits is difficult to achieve but extremely necessary for the safe and efficient work of mining crews.

Particularly important for the selection of appropriate methods and air conditioning equipment (group or central) is to determine the depth and length of ventilation routes and the length of routes needed to ensure effective ventilation and air conditioning of ice water transport to areas that particularly require cooling as well as the calculation of its efficiency based on the ratio of input power and installed power to the output of air conditioning.

Due to the fact that highly efficient air conditioning systems with a capacity of a few to several tens of megawatts air conditioning systems are based on the production of ice water in air conditioning machines i.e. water with a temperature of about 2 degrees Celsius. In view of the fact that highly efficient air-conditioning systems of several megawatt capacities are based on the production of ice water, i.e. water with a temperature of approx. 2 degrees Celsius, it is necessary to take into account the customer’s conditions consisting of the possibility of locating the ice water generators in the Surface Air-Conditioning Station and supplying the ice water via a shaft and then through corridor excavations to the mining areas and local coalfaces, and then, after it has cooled, discharging the collected heat and transporting the heated water to the surface of the ground and making the heat discharge.

In this case, it is necessary to reduce the pressure resulting from the depth of the shaft by means of heat exchangers or Pelton turbines in order to minimize costs by recovering energy from the turbine.

If it is necessary to locate the ice water generators in underground workings, it is necessary to adapt the heading by rebuilding it and transforming it into the Underground Climate Station from which the ice water is distributed through the network of pre-insulated (for the ice water) and uninsulated (for the return heated water) pipelines to the mining areas subject to cooling.

In this case, the location of the heat discharge is of crucial importance for the efficiency of the air-conditioning system. If we discharge warm water to the surface to collect heat energy through heat exchangers and use the heat obtained for example to preheat water in the mine bath, then through a system of free cooling or cooling towers or air coolers direct the water to the reservoirs and after preliminary purification through the shaft again to the ice water units.

Another important factor in planning industrial air conditioning installations is its durability, tightness, ability to regulate the mass flow of water and energy depending on the prevailing local climatic conditions (temperature and humidity), external temperatures and season is resistance to scaling and contamination of the system through the use of the highest quality materials including composite piping, titanium exchangers, efficient pumping systems that provide full monitoring of pressures and flows and readout and regulation of set and prevailing temperatures.

Titanium heat exchangers

We use titanium heat exchangers and full flow automation.

Composite pipes

Composite pipes used by us for transporting ice water ensure long service life, low weight for easy installation and resistance to dirt and calcification.
