Considering the settling of dispersed water in the water barrier when calculating the explosion-proof distance at the methane explosion in a mine

Abstract: Gas dynamics equations are used to simulate the interaction of shock waves with water or rock–dust barriers. The model is enhanced with the presence of dispersed water in the flow and its settling on the walls of the working. An approach to the implementation of the method for solving the problem of the propagation of shock waves in a branched network of mine workings, considering the interaction of shock waves with water barriers has been developed. The approach is based on the use of the numerical method of … Show more

“…The model is supplemented by the presence of dispersed water in the flow and the possibility of its settling on the mine working walls. An approach has been developed to implement a method for solving the problem of shock waves propagation in a branched network of mine workings, taking into account the interaction of shock waves with water obstacles [14]. An approach to determining the technically achievable levels of the current average dust concentration in the mine air per shift and methods for increasing the efficiency of assessing the dust content in coal mines are proposed.…”
