ASSESSMENT OF THE ACTUAL TEMPERATURE CONDITIONS IN THE CHAMBERS FOR PLACING FANS

Abstract

Purpose. Assessment of the actual temperature conditions in the chambers of gas suction installations in the mining and geological conditions of the “Pokrovske” Mine Administration. Method. Analysis and generalisation of the results of observations of the actual temperature regime in the fan chambers of the component installations. Results. An analytical comparison of the actual temperature regime in the chambers of gas suction units with the permissible one according to sanitary and hygienic standards was carried out. The rational parameters of the temperature regime are determined, which can be considered “conditionally” acceptable in the chambers of gas suction units, are determined in the mining and geological conditions of the “Pokrovske” Mine Administration. Scientific novelty The substantiation of the necessary physical parameters of the air entering the chambers of gas suction installations, for their ventilation, to ensure sanitary and hygienic standards for temperature has been carried out. The dependence of the air flow rate entering the chambers of ventilation gas suction units on its maximum allowable value , according to sanitary and hygienic standards, has been established.. Practical significance. It has been established that in order to ensure the standard temperature regime in the chambers of gas suction units in the mining and geological conditions of the “Pokrovske” Mine Administration, it is not advisable to use refrigeration units. This will reduce the economic costs of ensuring the standard temperature regime. Key words: recommendations, methane, goaf, temperature, ventilation.
