Abstract: Aiming at the mining technical problems of steeplyinclined and extremelythin veins of erdaogou gold mine, the resuing stoping with concrete pad is proposed. The comprehensive technical measures of adjusting mining and cutting structure ,changing bedding way, improving mechanization level and adopting the stoping method of two blasting mining operations and one resuing operation, the mining technical problems of steeplyinclined and extremelythin veins are solved effectively. The study results further show that the resuing stoping with concrete pad with the characteristics of high production capacity, low loss rate and dilution rate, low labor productivity and operation safety, it is suitable for the mining operation of steeplyinclined and extremelythin veins, especially suitable for the prevention and governance of ground pressure disaster, and it can also provide some reliable reference for the mines with the similar mining technical conditions with erdaogou gold mine.

Key words: Steeplyinclined and extremelythin vein, Intensified mining, Concrete pad,, Resuing stoping, Ground pressure disaster
