Abstract
Due to the large cross-section and dense chambers,the horsehead door of the shaft in the coal mine is prone to deformation,which has always been the difficulty of support control.The horsehead door of Dongpang new air shaft was taken as the engineering background,the deformation characteristics were analyzed,which were mainly manifested as spray layer falling off and anchor cable support failure,and the main causes of deformation are analyzed.In view of its deformation characteristics,the concept of comprehensive section support was put forward.Bolts,anchor cables,grouting and sheds formed three-layer reinforcement arches around the roadway,which could effectively improve the bearing capacity of surrounding rock and ensure long-term stability.Therefore,the full-section support scheme of anchor cable+grouting+U steel+concrete was determined,which effectively controlled the deformation of the ingate,and provided reference for the treatment of the ingate under similar conditions.关键词
