摘要
Abstract
In view of the geological conditions of the composite roof of the return air roadway in southen wing of Gubei Coal Mine, in order to ensure the support safety of the prepared roadway in the whole service life of the mining area, the rational bolt support parameters of the preparation roadway in group A coal of Gubei Coal Mine are determined by the "four-in-one"research means of theoretical analysis, analogy simulation, numerical simulation and on-site monitoring, and the technical scheme of full-length bolting and prestressing is proposed. Industrial tests have been carried out and the roadway has been running smoothly and safely. The 12-month observation of rock pressure shows that the maximum displacement of roof and floor is 140 mm, the displacement of both sides is 80 mm, and the deformation of roadway is small.关键词
