Abstract

The objective of the paper is substantiate the method of construction and design parameters of explosion-proof stopping for quick and safe remote sealing-off of the sources of complex fires and explosions in coal mines. Designed a new method of remote erection of explosion-proof stoppings in mine workings and mathematical model of mass transfer through the body of a stopping made of discrete material. Improved tactics for containment of underground fires and explosions due to rapid remote erection of explosion-proof stoppings. The technology of quick erection of stoppings made of rocks crushed by explosion for sealing-off of the emergency sections of the mine has been proposed. A computational model and a method for calculating the parameters of explosion-proof stoppings erected by the method of directed explosion have been created. The results of the calculations open the possibility to prepare the means of containment of dust explosions in advance and to improve the tactics of safe containment of explosions and fires.
