摘要
Abstract
In view of the gas governance problems of low permeability outburst coal seam, this paper tested the gas extraction technology of the protective layer mining and the high-pressure water jet cutting, and introduced a remote working face pressure relief protection pre-pumping technology and high-pressure water jet cutting test and effect, which increased signiifcantly the coal seam permeability coefifcient, realized gas enhanced extraction, eliminated the outburst danger of coal seam, this technology has wide application value in the similar condition of coal mine.关键词
