In the geological survey report of the new mine, all coal seam dust explosion identification data must be available. For each new depth of production mine, a coal dust explosion test should be conducted. The mine must establish a perfect dust-proof water supply system. Mining surfaces that do not have dust-proof water supply lines must not be produced.
The main transportation lanes, belt conveyors, inclined and horizontal lanes, uphills and downhills, transportation lanes and return lanes, excavation lanes, coal bunkers, coal eyes, coal discharge ports, and unloading points must be laid. Dust-proof water supply pipes and branch pipes and valves. Dustproof water should be filtered. Water mining and water mining areas are not subject to this limitation. All coal bunkers and coal eyes in the mine should maintain a roof of coal, not emptying; coal bunkers and coal eyes with water inrush can be vented, but after opening, coal bunker gates must be closed and diversion pipes installed. Coal eyes should not be used as a wind eye. Mining mines with dangerous coal dust and explosive coal seams must have measures to prevent and isolate coal dust explosions. The two wings of the mine, the adjacent mining area, the adjacent coal seam, and the adjacent coal mining face, the coal roadheading roadway is the same as the roadway connected to the coal roadway. The other places where the explosion is in danger with the roadway connected with it must be separated by a water shed or rock powder shed. The floating coal in the roadway must be cleared in time to clean or flush the deposited coal dust, and the rock powder should be regularly dispersed; the major roads should be regularly brushed.
Every year, mines should formulate comprehensive dust prevention measures, measures for preventing and isolating coal dust, and measures and management systems, and organize implementation. Mines should check at least once a week whether the installation location, quantity, amount of water or rock dust, and installation quality of coal and dust explosion-proof facilities meet the requirements.
