About a mine 265 m middle exploration with contrast

Southern hard rock mining enterprises subordinate mine, many with 60 ∼ 70 s of the old mine is given priority to, with service time prolonged, highlighted the low economic benefits, low capacity, safety, environmental protection, such as high risk, high cost of a variety of short board^[1].
