Description

Technical Field

[0001] The invention relates to the technical field of downhole equipment, and in particular to downhole particle collection equipment based on ultrasonic standing waves. Background Art

[0002] Mine ventilation technology has been in my country for several decades. At the same time, with the continuous development of science and technology and the continuous deepening of people's research on mine ventilation technology, mine ventilation technology has reached a new height. The pressure-equalizing ventilation technology is to suppress the diffusion rate of gas in the coal seam by balancing the wind pressure. By reducing the gas content in the underground working channel as much as possible, the pressure-equalizing technology can achieve the production and personnel safety of the working face, especially the working face of high-gas coal mines. Usually, the pressure difference is reduced to a minimum based on the concentration gradient principle, thereby reducing or even preventing the large-scale outflow of gas from the goaf. Based on the relatively low concentration of gas, if the wind pressure of the working face is increased, there will be no leakage from high to low gas concentration. However, since it is necessary to ensure the absolute pressure equalization of the fan equipment as much as possible, this is the premise for the smooth development of the entire ventilation process. A large number of practical operations have confirmed that once there is a pressure difference on both sides of the channel, the gas will diffuse from high concentration to low concentration, thereby entering the working face, which will pose a great threat to the personal and even life safety of the underground workers. Therefore, this technology requires a higher level of operation and management measures during implementation, so it is subject to certain restrictions during application. In addition, although fan pressure equalization is effective in suppressing gas gushing, it is not applicable when there is a large air leakage outside.

[0003] Existing ventilation equipment always extracts air passively, is unable to detect the gas concentration inside the mine, cannot assist ventilation, cannot provide early warning of gas abnormalities, and has a low level of intelligence. Summary of the invention

[0025] Specifically, as Figure 1-2As shown in the figure, the terminal server 2 can store the information transmitted by the central controller 1. The terminal server 2 conducts simulation processing on a large amount of data to form a quantitative analysis model. Based mainly on a large amount of monitoring data of ventilation gas, carbon monoxide and other toxic gases, under the guidance of ventilation network theory and ventilation sensitivity analysis, as well as the distribution and flow conditions of gas such as underground gas and carbon monoxide during a fire, in the acoustic wave monitoring of environmental noise and sudden noise, a quantitative analysis model in the sense of statistical analysis is established to analyze and determine the dangerous area of ventilation gas, the high-temperature spontaneous combustion area of coal in the coal wall, the gas emission law of the mine, and the fluctuation law of air flow and dangerous gases. Through the above analysis model and law, a corresponding acoustic wave peak model during the occurrence of relevant disasters is fitted, and finally the coupling relationship between disasters and acoustic wave changes is explored to realize the intelligent decision-making of the system and the pre-autonomous deployment of the mine particle collection equipment in the Internet of Things to the corresponding area to take disaster response measures.
