摘要
Abstract
In order to solve the problem of air leakage and oxygen supply in goaf caused by the crushing of protective coal pillar in the upper side section of No.74104 working face,the plastic plugging technology and plastic spraying technology were studied,and the opti-mal material ratio was tested to determine a reasonable ratio scheme and process flow.Field applications show that the plugging technol-ogy is scientific and reliable,the performance of plugging material is superior,being able to effectively reduce air leakage in goaf,reduc-ing the risk of spontaneous combustion in goaf.关键词
