The device developed by Ivan Smirnyagin, a Master's student at the Faculty of Radio Engineering and Electronics (also an engineer of Chinakal Institute of Mining of the Siberian Branch of the RAS), under the guidance of Alexey Bizyaev, a senior lecturer at the Department of Construction and Technology of Radio Electronic Devices at the Novosibirsk State Technical University NETI, will help predict a mining pit collapse.
Smirnyagin's device allows obtaining information about the collapse earlier than the existing analogues, additionally being more compact. The development has already been successfully tested at the mining companies of Kuzbass: the Tashtagolsky Mine, the Sheregesh Mine and the Kirov Mine in Leninsk-Kuznetsky.
"I ultimately expect to succeed in making the device the size of a smart phone. In addition, I am currently working on implementing a sensor system into the telecommunication network for the the real time information to be collected at the company's HQ control panel", said Ivan Smirnyagin.
The principle of the device operation is based on the electromagnetic wave detection that rock emits during destruction, and this data enables taking timely preventive steps for unloading a section of the mine massif. The development's unique character is that the signal shape and the degree of danger are displayed on the device's screen in real time. The development was presented at the XVI International Salon of Inventions and new technologies "The New Times" recently held in Sevastopol. "I have been working on this project since my first year of NSTU NETI studies (now Ivan is in the 2nd year of Master's degree). The equipment for electromagnetic radiation detection includes a portable device that can be used to predict dynamic mountain pressure events in the form of mountain shocks and carry out a set of measures to prevent it. That will help ensure the safety of mining operations and will be important at mines, delfs, while diagnosing old buildings that are in danger of collapse due to increased cracking in the foundation", Ivan Smirnyagin comments.
"The modern analogues are more cumbersome and heavy, and require special skills and competencies to work with. Some similar devices warn of the danger not in advance, but just a few seconds before the collapse. Moreover, the results can only be processed on a desktop. This happens due to the fact that they usually use a less modern element base and outdated algorithms and techniques. I've developed my own method of predicting collapses, which I'm going to patent this year. It is based on modern algorithms and the latest element base, "explains Ivan Smirnyagin.
Alexey Bizyaev, the project research supervisor, senior lecturer of the Department of Construction and Technology of Radio Electronic Devices, NSTU NETI noted that the unique character of the device is due to its ability to collect data. That can be used to build a neural network and start the self-learning process of forecasting dynamic mountain pressure events. "Similar devices are based on other physical phenomena and require contact with the rock, or are even based on actions that destroy the rock that must be accurately carried out for a long time. The fact that the new device can be used to make measurements on any part of the developed mine massif very quickly, safely and reliably is important for mining companies, "Bizyaev said.
