Siphon-based drainage system and method for gushing water in open-pit mines

Abstract

The invention relates to the technical field of drainage of gushing water in mining pits, and provides a siphon-based drainage system for gushing water in open-pit mines, including a first water storage tank that can be located at the lowest drainage point, and can be located at a location higher than At least one second water storage tank at the drainage point at the location of the first storage tank and a drainage device for draining the collected water in the first storage tank, the first storage tank and the second water storage tank are passed through a pipeline In communication, the pipeline is provided with a control valve assembly for controlling the flow and velocity of the water flow. Also provided is a siphon-based drainage method for gushing water in an open-pit pit, including three steps S1-S3. In the present invention, by arranging the water storage tanks according to the height of the drainage point, and realizing siphon through the pipeline, the collected water at a high place can be guided to the lowest water storage tank, so as to save the use of water pumps, pipelines, cables, etc., and not only save resources, but also improve work efficiency and reduce labor costs.

Description

technical field [0001] The invention relates to the technical field of drainage of gushing water in mining pits, in particular to a siphon-based drainage system and method for gushing water in open-pit mining pits. Background technique [0002] In terms of open-pit mine production, with the wide application of large-scale equipment, earthwork stripping and raw ore production are advancing at a relatively fast speed. For example, the production capacity of a large open-pit coal mine can exceed 20 million tons per year, but there are many practical difficulties in it, and new problems come one after another. The water inflow increased. A large amount of water is collected on the stripped flat plate, and the use and utilization rate of mechanical equipment are obviously reduced, which leads to construction difficulties and seriously affects the progress of the project. [0003] In the drainage operation of open-pit mine water, there are multiple drainage points. In the prior ...

For example, the production capacity of a large open-pit coal mine can exceed 20 million tons per year, but there are many practical difficulties in it, and new problems come one after another. increased water inflow

A large amount of water is collected on the stripped flat plate, and the use and utilization rate of mechanical equipment are significantly reduced, resulting in difficulties in construction and seriously affecting the progress of the project

[0003] In the drainage operation of open-pit mine water, there are multiple drainage points. In the prior art, a water pump is usually installed at each drainage point, and each water pump uses its own independent pipeline and cable to realize the drainage. However, it is easy to cause waste of electricity, and with the advancement of the mining face, the cables and water pumps are frequently moved, resulting in a great waste of manpower and time, which seriously affects the progress of mining and the quality of coal.
