| Popis: | The objective of this paper is to substantiate the method of construction and design parameters of explosion-proof stoppings for the quick and safe remote sealing-off of the sources of complex fires and explosions in coal mines. A new method was designed for the remote erection of explosion-proof stoppings in mine workings and a mathematical model of mass transfer through the body of a stopping made of discrete material. Tactics were improved for the containment of underground fires and explosions due to rapid remote erection of explosion-proof stoppings. The technology of the quick erection of stoppings made of rocks crushed by an 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. Cilj je rada utvrditi način konstrukcije i projektnih parametara protueksplozijske brane za brzo i sigurno daljinsko izoliranje izvora složenih požara i eksplozija u rudnicima ugljena. Dizajniran je nov način daljinskoga uspostavljanja protueksplozijskih brana u rudarskim radovima i matematički model prijenosa mase kroz tijelo brane od materijala u rasutome stanju. Poboljšan je način za suzbijanje podzemnih požara i eksplozija zahvaljujući brzomu daljinskom uspostavljanju protueksplozijskih brana. Predložena je tehnologija brzoga postavljanja brana od kamena usitnjenoga usmjerenom eksplozijom za izoliranje interventnih dionica rudnika. Izrađen je numerički model i metoda za proračun parametara protueksplozijskih brana uspostavljenih metodom usmjerene eksplozije. Rezultati proračuna otvaraju mogućnost da se unaprijed pripreme sredstva za zadržavanje eksplozivne prašine te da se poboljša metoda sigurnoga suzbijanja eksplozija i požara. |
