Problems solved by technology

For example, for the simplest two parallel air ducts A and B, if it is necessary to maximize the air volume passing through air duct B, then: not only the rolling door of air duct B needs to be opened to the maximum, but also the rolling door of air duct A needs to be closed to the minimum; and it is impossible to make the air flow through it reach its target air volume only by adjusting the air duct B itself. Moreover, when the air duct B is adjusted, it also affects other air duct

Abstract

The invention provides an overall automatic regulation device and method of a mine ventilation system. Various automatic adjustment and control air amount adjustment devices are combined optimally, a remote intelligent regulation server collects the ventilation condition of a whole mine and calculates the air demand amounts of all air using points, a feasible overall regulation scheme is worked out in good time, and all the automatic air amount adjustment devices are controlled and regulated through a communication network. As the various air amount adjustment devices are designed, the overall automatic regulation device is suitable for different mine environments. Therefore, under the condition of not affecting normal operation of production and conveying equipment, overall optimal regulation and control of the mine ventilation system are realized, and the mine can be supplied with wind during a normal period and a catastrophe period according to time and needs.

Description

technical field [0001] The invention belongs to the technical field of automatic control of mine ventilation, and in particular relates to a global automatic control device and method for a mine ventilation system. Background technique [0002] Mine ventilation is one of the important means to ensure mine safety, high efficiency and green mining. The core task of mine ventilation is to ensure the on-time and on-demand air supply to various underground wind sites. [0003] In the prior art, the downhole air volume is adjusted mainly by manual or local automatic adjustment methods. However, due to the complexity of the downhole ventilation system, the above adjustment methods are difficult to meet the needs of underground safety production. [0004] Furthermore, the modern downhole air volume adjustment mainly uses manual adjustment dampers and wind windows, and the adjustment method is very simple, which is difficult to meet the current complex underground environment needs. ...
