Optimization of an Experimental Stand with Four Nozzles for Assessing the Intensity of Irrigation in Underground Mining Sites

Abstract

This study presents an upgraded experimental methodology for analyzing the dispersion and hydrodynamic characteristics of sprinkler nozzles applicable in underground mining sites. This article is a scientific upgrade of the topic "Development of experimental equipment for testing fire extinguishing nozzles in underground mining sites". An improved stand equipped with four nozzles has been developed, which allows for a more precise assessment of the intensity of the water coverage on a protected area. The study includes measuring the spatial distribution of water through a network of measuring vessels and determining key parameters such as flow rate, pressure and uniformity of spraying. The achieved results demonstrate the possibility of effective calibration of fire extinguishing systems in order to minimize the risk of fire in an underground environment. A comparative analysis is presented with a previous stand with two nozzles, taking into account the advantages of the expanded configuration.
