摘要

Layout development working for demonstrating dust explosions and methane-air mixture is intended for the education and training of technical personnel and workers of coal enterprises and enterprises of the mining industry. Layout preparatory to demonstrate generation of dust explosions and methane environment is (see. Fig.1) model excavation at 14 adjacent to a pattern generation deadlock part of the front wall 1 and the end wall which model deadlock part of generation are made of Plexiglas of thickness 8-10 mm and allow you to see the inside of a layout. Rear, upper and lower part of the layout made of a steel sheet 2.3 mm thick and the wooden frame. In the inner part of the model development working deadlock part 1 are arranged on: the electrical cable 2; magnetic switch 3, the ventilation Double door lintel 4, 5 dummy miner, local ventilation fan installation 10 with the working and standby 11 fans, ventilation duct 12, shale barrier 15, collapsed rock 16, the lighting network 17. The rear wall portion stall pattern 1 mounted advance working device 6 for feeding methane and coal dust device 13. The produced methane assembly for igniting medium connection of cord 7 and 8 with a fork.; Layout allows to show the audience:; - a blast medium in methane cavity model deadlock part of generation 1 in pumping the explosive it methane concentration (9.5%, 5%, 15%, etc.), And thereafter pressing the trigger including an ignition device for methane-button ignition source medium 7 - magnetic starter, which because of the "insulation fault" with; roof collapse rocks 16 generating an arc at the input of the electrical cable 2;; - methane-air mixture explosion initiated by a smoldering cigarette "located in the mouth moulage miner 5;; - simulate the explosion pylemetanovozdushnoy environment.; - door opening in the ventilation crosspiece 4 and 5 fall moulage miner installed in the model deadlock part of generating one of the shock wave of the explosion;; - sound and light maintenance of methane explosion environment, provide emotional impact on the audience;; - triggering shale barrier 15 from the shock wave of the explosion partially maturing them suitable flame front when it is mounted with deviations from regulatory requirements;; - an emergency stop fans 10, 11 local ventilation ventilated stub generation part 1 and the preparatory blackout in mines 1 and 14;; In addition to the above layout allows you to:; - continuous monitoring of the concentration of methane in the cavity model deadlock part of generating methane from a stationary control sensor 9;; - The model used as a simulator to conduct control of methane and carbon dioxide in the atmosphere in the model deadlock part of generation 1.
