Abstract
In order to determine the best blasting hole spacing on the basis of physical principles and control hole arrangement for increasing the gas permeability of coal seam with carbon dioxide blasting technology,this paper used FLAC3D and Comsol software for different spacing between long-short radius of blasting and the blasting effect to carry on the numerical simulation.The results show that the blasting spacing is about 5 m,and about 7 m for blasting hole spacing.When the hole arrangement and control is in the middle of the adjacent blasting hole,liquid carbon dioxide porous continuous blasting can achieve ideal blasting anti-reflection effect.The larger the radius of the control hole,the more obvious the anti-reflection effect,and the higher the gas extraction efficiency.关键词
