Abstract

Taking the deep gob-side entry under the mined gob in the Nantun coal mine as the background, indoor physical mechanic property research, situ engineering geomechanics analysis, theoretical formula analysis and three-dimensional numerical simulation were adopted. The type of deformation mechanism of this roadway was confirmed. The coupling control technology of constant resistance was proposed and used in practice successfully in situ engineering. Practice was proved that the coupling technology of constant resistance based on NPR bolt could absorb the energy accumulated in surrounding rock and ensure the total safety of the roadway.
