Mining multistage intelligent drainage apparatus and method

Abstract

The invention discloses a mining multistage intelligent drainage apparatus and method. The apparatus comprises a working face water speed control and drainage unit. The working face water speed control and drainage unit comprises a water speed data acquiring module, a water speed data processing unit, a control unit and a water speed warning unit; the water speed data acquiring unit, the control unit and the water speed warning unit are all connected with the water speed data processing unit. The working face water speed control and drainage unit is capable of monitoring water incoming speed of a water bin throughout the day, quantity basis is provided for pump starting of a regular drainage unit, problems of overflow, overload and switch ageing, caused by frequent start-stop of a centrifugal pump, are decreased, the service life of the centrifugal pump is prolonged, necessary time is provided workers to evacuate from a site, especially in water inrush emergency, and life safety of staff is further ensured.

Description

technical field [0001] The invention relates to the field of mines, in particular to a multi-stage intelligent drainage device and method for mines. Background technique [0002] Most of the underground rock mass under the mine has cracks, joints, fault structural planes, and underground water layers, which cause water seepage, water gushing, and water inrush incidents on the working face to occur frequently, which brings inconvenience to on-site production and saves the lives of employees. Security poses a threat. [0003] At present, although some articles have proposed measures to use the ground to control underground drainage, many mines still use manually controlled electric pumps, air pumps, and centrifugal pumps for drainage due to high costs and unsuitability for harsh underground environments. In the context of the downturn in the mining industry, saving production costs and human resources is obviously the top priority. The traditional artificial drainage is to d...

AI Technical Summary

Problems solved by technology

Today's drainage methods cause unnecessary waste of electrical energy

On the other hand, frequent start and stop of the motor will cause overcurrent, overload, switch damage, etc., which greatly shortens the service life of the machine and increases the investment in equipment costs to a certain extent.

The situation of water seepage varies from time to time. If the workers are slack or the drainage is not timely, it is likely to affect the normal production of the working face.

Especially at present, domestic emergency measures for water inrush incidents are still lacking, seriously affecting the safety of employees and the economic benefits of enterprises.

[0004] At the control end of the drainage system, the operation process of the centrifugal pump is still relatively cumbersome

Especially in the water supply stage of the pump body, the adjustment of the valve is better for experienced workers, but for newcomers, poor control may cause the phenomenon of pump burning, which will affect the normal production of the working face
