EVALUATION OF WATER CONSUMPTION FOR EXPLOSION-PROOF IRRIGATION OF CUTTING TRACES OF UNDERGROUND EXCAVATING MACHINES
Purpose. Development of an engineering criterion for evaluating water consumption for cooling the cutting path of excavation machines to prevent an explosion of a mixture of air with methane and coal dust. Method. Compilation of the heat balance equation for heating the cutting trace with the cutter and its cooling with irrigation water. Results. A criterion was obtained for evaluation by coal enterprises and conciliation organizations of the compliance of the water consumption of the internal irrigation system of imported mining machines with the current domestic requirements for explosive safety by one of two factors - prevention of the flash of the cutting trace. Scientific novelty. It consists in the assumptions made, which made it possible to reliably (with a solid margin) determine the cost of cooling the cutting trace based on only one parameter - the drive power of the executive body. Practical meaning. The developed criterion allows for a coordinated policy of experts of coal enterprises, supervisory and coordinating bodies in matters of conformity of the parameters of the irrigation systems of imported mining machines with the requirements of explosive safety. Key words: explosion safety, dust methane air mixture, cutting marks, frictional sparking.
