AP19680130 "Ensuring industrial, environmental safety and completeness of extraction of minerals in the conditions of the failure hazard of the Earth's surface"

Relevance

The relevance of the project is determined by the need to improve industrial and environmental safety during the operation of mining facilities in conditions of high risk of failure. With the intensification of underground work and the aging of infrastructure, the risk of sudden destruction increases. The development and implementation of innovative methods for precise localization of the possible collapse zone allows timely preventive measures to be taken, minimize economic losses and prevent accidents. This is especially important for the sustainable development of fuel and energy companies and the safe design of infrastructure facilities.

Purpose

Spatial localization of an area with a high level of failure risk located in the zone of influence in the zone of influence of destruction processes within the IHL

Expected and achieved results

Development of 2 methods and devices, their practical use for determining the coordinates of the source of destruction in a rock mass. One that does not require prior measurement of the propagation velocity of a seismic acoustic wave by iterative methods. The second is the determination of the coordinates of the fracture site in the rock mass based on a preliminary determination of the velocity of propagation of the seismic acoustic wave along the bearing to the source of the seismic acoustic emission. The methods ensure the accuracy of determining coordinates within 3 m. By measuring the fracture parameters using two developed methods based on the ultrasound tomography method, the current values of the GSI rating were obtained and its effect on determining the boundaries of zones with different levels of failure was assessed. Based on a comparison of the analysis of the results of measurement of crack parameters by ultrasound and Fourier analysis data of the SAE accompanying crack formation processes, an assessment of the possibilities of their identification by the spectral characteristics of the SAE was carried out. Based on the results, 4 patents (3 Kazakhstani and 1 Eurasian) and two articles in the journal recommended by the KOKNVO were obtained. 1 article has been sent to the journal Mechanical Systems and signal Processing with a percentile of 98 (Q1) and 1 article has been prepared for submission.
