Method for detecting stability and economic property of mining main ventilator in real time

Abstract

The invention discloses a method for detecting the stability and the economic property of a mining main ventilator in real time. The method comprises the following steps: 1, an air volume sensor detects the air volume of the main ventilator in real time, and a data acquisition device acquires a real-time air volume signal detected by the air volume sensor and transmits the signal to a computer in real time; 2, the computer receives the real-time air volume signal transmitted by the data acquisition device, and compares the real-time air volume signal with a main ventilator stability and economic property evaluation model when the rotating speed, pre-constructed by the computer, of the main ventilator is n minute to obtain a comprehensive stability and economic property operation state of the main ventilator. According to the method, the steps are simple, and the method is convenient to implement and low in cost; the stability and the economic property of the main ventilator are effectively combined together, so that the stable and economic operation of the main ventilator can be realized favorably, and the use effect is good.

Description

technical field [0001] The invention belongs to the technical field of mine ventilation safety, and in particular relates to a method for real-time detection of the stability and economic efficiency of a mine main ventilator. Background technique [0002] The main ventilator is usually compared to the respiratory system of an adult. It is responsible for the ventilation of the entire coal mine or a large area in the entire coal mine, and determines the underground ventilation of the entire coal mine. Therefore, it needs to run day and night. Once the main ventilator is shut down due to failure , will directly affect the safe production of coal mines, and even bring catastrophic accidents. Therefore, the safe operation of the main ventilator is the basic guarantee for the safe production of coal mines. [0003] In view of the fact that the characteristic curve of the axial flow main fan generally has the characteristics of a saddle-shaped hump, and the area to the left of th...

Problems solved by technology

In view of this situation, the real-time efficiency of the main ventilator can only be accurately obtained through on-site testing

At present, there are many researches related to the main ventilator in the prior art, but most of them are simply studying the monitoring of the main ventilator parameters or the research related to the working range of the main ventilator and its adjustment method. The precedent of combining the stability and economy of the main ventilator can not realize the comprehensive and comprehensive monitoring of the parameters of the main ventilator on the coal mine site, and can't understand the working status of the main ventilator on the coal mine site well.
