INVESTIGATION OF FILTRATION PERMEABILITY OF BARRIER PILLARS AT PERFORMING MINING OPERATIONS NEAR THE ISOLATED FIRE AREA
Journal Title: Вчені записки Таврійського національного університету імені В. І. Вернадського. Серія: Технічні науки - Year 2018, Vol 29, Issue 5
Abstract
In the article, a numerical study of the filtration permeability of a coal-rock massif with an isolated area, active mine working and a barrier pillar, depending on its stress state is performed. Recommendations for determining the safe width of the insulating pillar in the conditions of Mine Management “Pokrovskoye” are developed. The fire gases filtration into the Conveyer Gangway of the 7th Southern “prim” Lava of Block 10 was excluded, the gas safety at the mining work was ensured.
