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.
