Abstract

The invention discloses an intelligent drainage method for an underground mine. According to the method, the power consumption of pump station drainage is predicted according to the field water level, and each stage of pump station with the goal of reducing the power consumption cost is scheduled and adjusted. The upper stage of pump station and the lower stage of pump station are in communication connection through a network. During drainage, different control measures are taken for the bottommost pump station and the regional pump stations except the bottommost pump station; and if only the single-stage pump station exists, the control strategy of the bottommost pump station is directly adopted. According to the method, prediction of electricity consumption is achieved by combining data such as energy consumption and the field water level, a scheduling plan instruction is made through prediction, balance coordination control over the underground water level is achieved, the purpose of peak clipping and valley filling to the maximum degree is achieved, overflow is avoided, and meanwhile, electricity consumption is reduced.

Description

technical field

[0001] The invention relates to a mine drainage method. Background technique

[0002] The pumping stations of the mine will be upgraded step by step according to the characteristics of low to high terrain this summer. The pumping stations are not isolated, but connected through discharge pipelines. The groundwater is raised to the surface step by step from the bottom pumping station (called the uppermost pumping station), and the bottom pumping station contains at least one lower pumping station.

[0003] The water intake of the pumping station comes from a wide range of sources, and the amount of water intake is greatly affected by human and natural factors. Much of the intake water is muddy water in the filling materials, and the filling time and water volume are uncontrollable. The number of water inlet pipes is different, and the water inlet flow of each water inlet pipe changes in real time. There is a cascading relationship between each pumping statio...
