Abstract
In view of the problems of relatively prominent coal dust,harsh working environment,easy induction of coal dust accidents and others during the production process of the three soft coal seams in Gaocheng Coal Mine,experiments and explorations are conducted on the setting method of working face shallow hole water injection pseudo oblique drilling hole in the 23041 fully mechanized mining face,and a comparative experiment is conducted between this method and the current used setting method of water injection vertical drilling hole.The practice proves that the setting method of working face shallow hole water injection pseudo oblique drilling hole can reduce the amount of dust generated during the production process of the fully mechanized mining face,which is of great significance for promoting safety production.关键词
