[0045]

[0046] In the above formula (1), C represents the ore layer permeation water pressure injection constant, μ represents the dynamic viscosity coefficient of the leaching agent, and L 孔间距 represents the spacing between the pumping holes, k represents the permeability of the ore layer, and a represents the water-passing area at the bottom of the well.

[0047] S113: Calculating based on the injection volume, the density of the leaching agent and a preset friction coefficient of the inner wall of the injection pipe to obtain a surface pipeline resistance pressure injection constant;

[0048] In this step, the surface pipeline resistance pressure injection constant is:
