Research status and development tendency of mine fully- mechanized heading equipment technology

According to the technology,application status and existed problems of the heading equipment applied to a fully- mechanized roadway heading face,the pap er introduced key technical bottleneck of the mining and excavation unbalance and the gap between the technical performances of the domestic roadheader and the overse as. This paper pointed out the main factors affected to the service life of the picks during the hard rock cutting process and the causes. This paper analyzed the achieved p rogresses in the adaptive cutting,performance detection and fault diagnosis,planning of the cutting route ,coal and rock recognition,positioning and orientation of the machin e body,status monitoring and measuring,remote communication and other intelligent technology aspects and stated the present status of the matched equipment and key te chnology of the fully- mechanized heading. Finally,the paper provided the development direction and proposals on China fully- mechanized heading equipment.
