Various Draining Mines Open
Efforts to prevent the flow of water into the excavation site inbox. This is generally done for handling groundwater and water from surface water sources.
a. Siemen method
Pd every level (bench) dr mining fitted size 8 inch pipe, each pipe end BWH TSB DIBAG drilled lb2 (Perporasi), where the water pipe with berlb2 Berhub tnh, SHG at BWH bag pipes will collect water which subsequently discarded.
- System Ring
Created bbrp digging wells within an area ta, where they will sumur2 membtk a series regular and decommission sumur2 who had strung together one with the other by a main pipe that comes pump.
- System Stagered Ring
According to the theory of atmospheric tek interchangeable with the water sucking kedlmn 10.33 m ttp Because there is resistance (friction loss) pd pump system, suction adl max mk 6-7 m. For pd suck water depth within a less used bbrp THP mk pumping. This way adl dr bbrp way system combined with gol mendpt HSL ring pumps max.
b. Electro Osmosis methodWhen clay soil consists of clay, then pumping will work hard to do because there capillarity properties contained in clay soils. This method uses a rod anode and cathode, where elements electrified the pore water contained in the rock will flow towards the cathode (lb wells) who then collected and pumped out.
c. Method of Cutting
To observe groundwater conditions in which the excavated soil to the extent of the aquifer. Terpotongnya with groundwater flow is the area downstream would be no watertight / cemented manner.
d. The combination of the aperture hole method UndergroundOpenings by making a hole in the ground leveled to accommodate the flow of water perm dr. Bbrp lb or 1 lb wells wells made to channel water into the tunnel BWH perm tnh TSB. Because the effective way the water will drain itself scr g thus dispense pump.
