Thin vein resources are an important part constituting rock gold mining in China and the world.The mining process and development trend of steeply dipping narrow-vein resources in rock gold mines at home and abroad in recent years are introduced comprehensively,with the emphasis on the processes and problems of shrinkage mining method,medium-long hole mining method,resuing and fill mining method,dry fill mining method,cemented fill mining method,small sublevel caving mining method.The steeply inclined thin vein mining technology and the development direction in rock gold mines in the future are discussed.It provides a reference for safe and efficient mining of thin veins in underground rock gold mines.
