Embodiment Construction

[0021] like figure 1 , 2 , Shown in 3, mine water tank dredging method, this method comprises the following steps:

[0022] A. A material delivery pipeline 4 is installed in the trough 5 of the fully mechanized mining face 3, one end of the material delivery pipeline is connected to the water tank arranged on the fully mechanized mining working face, and the other end of the material delivery pipeline leads to the working face goaf 2; a tee 1 is installed on the feed pipeline, and the opening on the tee that is not connected to the feed pipe is blocked by a blind plate 7;

[0023] B. When the working face starts mining, use the cleaning equipment to carry out dredging, and at the same time open the blind plate on the tee at the end of the feeding pipeline, and the mud formed by the silt in the water tank enters the goaf through the feeding pipeline;

[0024] C. During the sludge conveying process, the pipeline at the end of the conveying pipeline will be gradually blocked du...

Abstract

The invention relates to a dredging method and device, and in particular to a mine sump dredging method and device. The mine sump dredging method comprises the following steps that A, a material conveying pipeline is installed in a gate road of a fully mechanized coal mining face; B, when a working face starts stoping, dredging is conducted through bin cleaning equipment; C, sludge is conveyed; and D, clear water obtained after slurry entering a goaf is precipitated enters a main water sump through a drainage roadway and is conveyed to a ground mine water treatment station through main water sump drainage equipment. The invention further relates to a mine sump dredging device. The mine sump dredging device comprises a sump and the material conveying pipeline and is characterized in that one end of the material conveying pipeline is connected with the sump, the other end of the material conveying pipeline leads to the goaf of the working face, a tee joint is installed on the material conveying pipeline, and openings in the tee joint which are not connected with the material conveying pipeline are blocked through blind plates. The mine sump dredging method and device have the characteristics of high bin cleaning efficiency, good environmental protection effect, obvious economic benefit and the like.

Description

[0001] Technical field [0002] The invention relates to a dredging method and device, in particular to a mine water tank dredging method and device. Background technique [0003] The water tank is an indispensable part of the mine drainage system. It has two main functions: one is to store water, and the other is to precipitate. The sediment in the tank needs to be cleared and dug out in time, otherwise the effective volume of the tank will be reduced. When encountering a sudden water gushing, the water in the tank will overflow and cause the risk of flooding the parking lot at the bottom of the well. At present, the dredging of underground water tanks at home and abroad is still one of the difficulties and focuses of water tank management. There are mainly three domestic mainstream ways of desilting tanks, using tank cleaning devices for dredging, combined dredging with mud pumps and jet pumps, and dredging with central sewage pumps. However, during the operation of the ab...
