Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings.

[0042] Underwater mining method of the present invention, its steps are:

[0043] ① First, use a rock-breaking device or other blasting methods to break the underwater ore deposit to ore particles that meet the requirements of the lifting pipeline 4;

[0044] ②The lifting pipeline 4, lifting pump 5 and hydraulic ore suction device 1 are placed underground through the ground platform drilling tower 7, and when the hydraulic ore suction device 1 hits the bottom, the lifting pump 5 is started to deliver clean water;

[0045] ③ The hydraulic ore suction device 1 keeps the ore particles at the entrance of the lifting pipe 4 in a suspended state;

[0046] ④ The ore particles are lifted into the ground storage pool 10 through the grid screen 102, the lifting pipeline 4, the lifting pump 5 and the delivery pipeline 9;

[0047] ⑤The ore settles ...

Abstract

An underwater mining method and its devices, with the following steps: (1) rock breaker or other blasting methods are used to break the underwater mineral deposit into the ore particle size that meets the transport requirement of the lift pipe; (2) the lift pipe, lift pump and hydraulic mineral sucker are arranged in the shaft. When the sucker touches the bottom, the lift pump will be started to convey clear water; (3) the sucker keeps the ore particles at the inlet of the lift pipe in a suspended state; (4) the ore particles are lifted to the ore storage tank on the ground; (5) the ore settles in the tank. The deslimed clear water is discharged into the shaft; (6) the remote control station is responsible for monitoring and control; (7) after mining is finished, the hydraulic mineral sucker will be stopped. When clear water comes out of the outlet of conveying pipe, the lift pump may be shut down. This system consists of hydraulic mineral sucker, underwater space probe, lift pipe, lift pump, remote control station, conveying pipe and mineral storage tank on the ground. The present invention has the following main advantages: simple and compact structure, easy operation, high safety and high mining efficiency.

Description

technical field [0001] The invention mainly relates to the field of mining methods and equipment, in particular to an underwater mining method and its device. Background technique [0002] Among the many sedimentary metal deposits in my country, they are characterized by deep burial of deposits, large amount of groundwater, and complex hydrogeological conditions. If the water blocking and drainage method is adopted for underground mining, the economic benefits of ferrous metal ore and low-value ore deposits are difficult to be guaranteed. Furthermore, the geological conditions of sedimentary mineral deposits are relatively poor, and safety accidents are prone to occur. With the advancement of mining technology and the development of automation technology, especially the development of offshore oil and deep sea mining technology has made undrained underground mining methods possible. Therefore, unmanned and undrained mining methods should be one of the solutions. [0003] ...
