Abstract
Acting 14214 working face in 4#coal seam of Dongqu coal mine as an example, according to the occurrence characteristics of the nearer distance between 2# and 4# coal seam, analyzed the theoretical failure depth of lfoor strata in mining 2# seam, studied the roof strata occurrence of 4# coal seam mining, determined the support parameters of working face hydraulic support, and proposed the control technology of fractured roof grouting of the under-group coal seam group.关键词
