On Innovation Technology of Undersea Panel Mining Method of Sanshandao Gold Mine

Sanshandao Gold Mine is one of the modern pit mines with the largest production scale and highest equipment level. A full set of trackless mining equipment is introduced and trackless underground mining is realized. Suitable mining method is adopted according to the type of the stope. Through improving mining techniques, changing the structure parameters of the stope, improving the construction process, drilling and blasting technology and packing, the mining strength and ore removal efficiency can be improved and the loss impoverishment rate and mining cost can be reduced.
