Intelligent ventilation regulation and control system for underground workplace of metal mine and method

Abstract

The invention discloses an intelligent ventilation regulation and control system for an underground workplace of a metal mine and a method. An external input system, a required air volume calculation system and a three-dimensional intelligent visual ventilation regulation and control platform are integrated in a ground surface dispatching center; a ventilator speed regulation control system is arranged in an underground fan control chamber; a workplace environment parameter monitoring system is arranged in an underground ventilation machine room or a workplace air return roadway; a database is stored in an industrial personal computer; and a network communication system connects the three-dimensional intelligent visual ventilation regulation and control platform, the ventilator speed regulation control system and the workplace environment parameter monitoring system through optical fibers. According to different working states of the underground workplace, a ventilation system of the workplace can be intelligently regulated and controlled through synchronous monitoring and real-time feedback of environmental parameters, the effective air volume rate of a pit is increased to the maximum extent, and decisions and support are provided for management, optimization and adjustment of the ventilation system of the mine.

Description

technical field [0001] The invention relates to the technical field of ore mining, in particular to an intelligent ventilation control system and method for an underground working place of a metal mine. Background technique [0002] my country's metal and non-metal mines have entered the stage of deep resource development. The ventilation lines of deep mining have become longer, the ventilation resistance has increased, and the energy consumption to maintain the mine design air volume is high. Most mines have large-scale multi-stop dynamic mining, the production capacity of the middle section is inconsistent, the demand for air volume in the workplace is diversified, the distribution is unreasonable, and the effective air volume rate is low. Therefore, how to realize the transition from rough mine ventilation to fine dynamic one, and to protect the underground working environment and the physical and mental health of workers to the greatest extent, has become an urgent probl...

Problems solved by technology

This method does not take into account the impact of mining technology and blasting procedures on the required air volume when calculating the air volume required for the workplace

At the same time, there is no clear setting of the criteria for judging the monitored air volume value (actual air supply volume) and the target air volume value (actual air volume demand), and the impact of harmful gases such as CO in the workplace on the air volume demand and air supply volume is not mentioned.

[0007] To sum up, combined with the design characteristics of the metal mine ventilation system, the fan type is generally selected according to the ventilation resistance and air volume during the period of difficult ventilation, and the designed air supply capacity is too large, especially in the initial stage of mine production and after the ventilation system renovation, the work site needs Both the air volume and the air supply volume have changed greatly, how to efficiently match becomes a difficult problem
