Embodiment 1

[0026] The invention relates to an ore storage and anti-clogging process in a high-speed chute in phosphate rock mining. A vibrating table is arranged on the upper mouth of the chute, and a vibrating rod is extended downward into the chute. When the vibrating table is working, the vibrating rod vibrates the slag in the chute. Its main technological process is as follows:

[0027] 1) Construct a drainage ditch around the upper wellhead of the chute. Avoid water flooding into the chute, accelerate the hydration of the argillaceous shale in the slag and the sinking of the dolomite powder, and the slag will harden and cause the blockage of the chute.

[0028] 2) Fabricate and install a vibration table at the upper wellhead of the chute. The vibrating table is installed directly above the upper mouth of the chute, on a bracket at a height of 2.5 meters from the grid screen. The base of the vibrating table is not less than 1.5 meters away from the edge of the chute and is on a stab...

Abstract

The invention discloses an anti-blocking technique for stored ores of a high orepass during phosphate ore mining. A vibration table is arranged at an upper opening of the orepass; a vibration rod downwards stretches into the orepass, and when the vibration table works, the vibration rod is used for vibrating slag in the orepass. The technique is simple; the vibration rod is installed in the orepass directly; when the orepass is not blocked, a vibration facility does not need to be started; when vibration dredging is needed, a starting button is operated, and therefore operation is easy; and the safety and reliability coefficients are high, and the slag is loosened and discharged directly through small-amplitude vibration of a steel pipe.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to an ore storage and anti-blocking technology for a high-speed chute in phosphate rock mining. technical background [0002] The ore-drawing chute is used to connect the upper and lower middle sections and temporarily store ore or waste rock. The ore-drawing ability of the ore-drawing chute directly affects the economic benefits and production capacity of the entire mine. Once blockage occurs, it will seriously affect the normal production of the mine, and even cause shutdown. Therefore, preventing ore-drawing chute blockage and effective dredging after blockage are issues that underground mines attach great importance to. When the ore-drawing shaft of the unit was blocked, the normal production was seriously affected. After the chute is blocked, it is necessary to unblock it safely and quickly, and resume production in time. It is necessary to determine the treatment method accor...
