Present Status and Outlook on Rapid Heading Technology of Mine Rock Roadway in China Coal Mine

ZHAO Hong-wei(Beijing Tiandi Huatai Mining Engineering and Technology Company Ltd.,Beijing 100013,China)  
In order to improve the heading speed and mechanization level of the mine rock roadway in China coal mine and to solve the disproportion situation between mining and excavation of the coal mining face,the technical status and features of the three mechanized operation lines were introduced manly in China coal mine.With references of the domestic and overseas experiences,the technical tendency of the mine rock roadway rapid heading was analyzed.The study provided two rapid mechanized heading operation lines of the mine rock roadway and analyed out the advantages and disadvantages as well as the suitable application conditions of the two heading operation lines.The two heading operation lines were the hydraulic drilling rig with the side dumping loader and the mine roadheader with the shuttle cars and belt conveyor.The paper pointed out that the first rapid mechanized operation line with the drilling and blasting method should be developed for the rapid heading of the mine rock roadway in first priority.The construction technique and technical equipment issues should be studied to sovle the general problems of the domestic mine roadway heading.
