Description

Technical Field

[0001] The utility model belongs to the technical field of open-pit mine drainage, in particular to a device for draining water-containing blastholes in open-pit mines. Background Art

[0002] The bench height in open-pit mines is primarily determined by the specifications of the mining equipment. Typical bench heights exceed 10 meters, and the drilling depth using rotary drills is typically 11-12 meters (including 1-2 meters deeper). As mining levels decline, the number of blastholes containing water gradually increases. Based on operational practices and observations and analysis of water inflow from blastholes, blastholes containing water are primarily seepage holes within rock fissures. The depth of water accumulation in blastholes varies with the groundwater level and the amount of water in these fissures, generally ranging from 2 to 6 meters. During the rainy season, groundwater can seep into or directly flow into the boreholes. Furthermore, rainwater raises the groundwater level, increasing water accumulation within the boreholes.

The device is characterized by comprising a rotating chassis, a lifting arm disposed on and connected to the rotating chassis, a telescopic arm connected to the lifting arm, and a pumping unit disposed on the telescopic arm. This device has a simple and reliable structure and utilizes a submersible pump to quickly drain water from the blasthole. This allows the use of lower-cost ammonium nitrate explosives instead of emulsion explosives, reducing blasting costs.

[0036] The working principle of the water-containing blasthole device for open-pit mines provided by the utility model is as follows:

[0037] The first step is to start the servo motor 5. Under the action of the two rotating rods 1 and 4, the hollow winding roller 3 can be rotated to release the wound water suction hose 10. At the same time, under the cooperation of the pulley 1 20, the pulley 2 21 and the connecting belt 22, the two rotating rods 2 9 can drive the guide wheel 8 to rotate to guide the released water suction hose 10 and put the metal pipe 11 into the blast hole (the diameter of the metal pipe 11 and the clamping block 12 is smaller than the diameter of the blast hole, and the expanded diameter of the water suction hose 10 is also smaller than the diameter of the blast hole). Under the action of continuously releasing the water suction hose 10, the metal pipe 11 can be gradually lowered, and the water pump 15 is started. Under the cooperation of the water suction pipe 16, the connecting pipe 6, the hollow winding roller 3, the water suction hose 10 and the metal pipe 11, the water in the blast hole is extracted and then discharged through the drain pipe, which makes the structure simple and avoids the problem of damage caused by putting the submersible pump into the blast hole, thereby affecting the use of the pump.

[0038] The second step: through the cooperation of the reeling mechanism, the guiding mechanism and the pumping mechanism, continue to pump water. When the metal tube 11 descends and cannot pump water, the pumping hose 10 can be reeled by the cooperation of the reeling mechanism and the guiding mechanism.
