Abstract: Taking the goaf disposal of an underground mine as the engineering background,according to the goaf scale,mining method and the surrounding rock conditions,the goaf caving disposal scheme of the surrounding rock of roof and floor of the goaf based on deep hole blasting technique is proposed.The goaf is filled with the collapsed surrounding rock,besides that,the reasonable deep hole blasting technical parameters are designed.Through meticulous design and construction,the hidden dangers in the goaf area have been successfully eliminated,and the mine safe production has been ensured,besides that,the experience of goaf disposal is accumulated.

Key words: Underground mine, Goaf disposal, Deep hole blasting
