Embodiment Construction
[0020] In order to further describe the present invention, a method for dredging and sludge disposal of an open-pit pit according to the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] Such as figure 1 As shown, a method for dredging and sludge disposal in an open pit, the construction steps are as follows:
[0022] Step 1: Build side cut-off ditches 2 at the slope toe of side cut-off 1 in the open-pit stope, lead the intercepted water directly to the drainage tank pool 6, set up multiple cut-off ditches to reduce the amount of water flowing into the bottom of the pit, and relieve the buoyancy tank at the bottom of the pit Suction pump 5 pressure.
[0023] Step 2: The bottom of the open-air pit includes the upper shallow sedimentation water 4 and the bottom sedimentation silt 3. A floating tank drainage pump 5 is arranged from the deep water area of the mining pit with a relatively shallow a...
