Abstract:In order to solve the problems of a mining and excavation unbalancing and the mining and excavation connection contradiction in China coal mine,with an analysis on the present status of the mine heading technology and equipment at home and abroad,the paper dis-cussed the main problems of the heading and bolting parallel operation and the hard rock cutting,which could restrict a mine roadway rapid heading and introduced a heading and bolting integrated combined operation and a new technical development of the hard rock cutting,in-cluding the hydraulic bolt drilling system on a boom type roadheader,a complete equipment for a continued rapid heading in a single mine roadway,a rapid heading system and others.Finally,the paper had a prospect and proposals on the development orientation of the mine road heading technology and equipment.
Keywords:mine roadway headingheading equipmentunbalance between mining and headingrapid headinghard rock cutting
