文摘Based on the dividing of derormation zones of tailentry in working face and the classification of driving metbods, toking the way of field measurement, this paper fiuds out some changing regularities of main deformation parameters of a tailentry in 2# coal seam in Suncun Colliery with the incrcasing of mining depth, and puts forward some layout methods to protect the tailentry in deep mining.
