Description
шегос забо выработки с высокой скоростью поступает в движущуюс горную массу и призабойное пространство, обеспечива его флегМатизацию .The high-speed drilling enters the moving rock mass and the bottom hole, ensuring its phlegmization.
Величину газа 4 и объем оболочки 3 выбирают такими, чтобы обеспечивалась фпегматизацн атмосферы призабойного пространства.The magnitude of the gas 4 and the volume of the shell 3 is chosen so as to ensure the phlegal atmosphere of the bottomhole space.
Гак, например, при использовании в качеств инертного газа азота концентраци его в пр 1легазовой смеси должна быть не менее 34%, tлeкиcлoгo газа - 26%, гели - 40%.A hook, for example, when using nitrogen as an inert gas, its concentration in the aforementioned 1-gas mixture should be at least 34%, the gas-26%, and gels - 40%.
Предлагаемый способ вл етс одним из : ффективных направлений по решению пробх емы предотвращени взрывов пылегазовых сйесей при взрывных работах от выгорающеf:O , зар да, длительность существовани которого может достигать 10 мин и более.The proposed method is one of: effective directions for solving problems of preventing explosions of dust and gas explosions during blasting operations from burning out: O, a charge whose duration can reach 10 minutes or more.
