The invention relates to a process for striping and mining
solid ore rock masses of a surface mine, which comprises a step of drilling a blast hole array, wherein the blasthole array comprises a plurality of rows of blast holes; adjacent rows of blast holes are mutually staggered along the directions of the rows; each blast hole corresponds to a non-blast hole of the adjacent row of blast holes; on each row, the distance between each two adjacent blast holes serves as a hole
pitch; and the distance between each two adjacent blast hole rows serves as a row
pitch. The process is characterized in that a small-aperture
drill bit and a
small hole network spacing are selected to
drill the holes; the rock drilling speed is improved for more A times than before; the construction operation is carried out according to the
small hole network spacing; the number of the drilled holes is increased to B times that of the original drilled holes; the area of each drilled hole is equivalent to one Bth of the area of the original drilled hole; and both A and B are natural numbers greater than 1. According to the invention, the boulder frequency and the blast root residual ratio can be greatly reduced, the striping and mining operations are continuously carried out, the process is convenient to operate, other investment is not required, the explosive load is unchanged, the drilling time is shortened, and the secondary blast quantity is greatly reduced.
