Employees of the Siberian Research Institute of Geology, Geophysics and Mineral Raw Materials, as well as the A.A. Trofimuk Institute of Petroleum Geology and Geophysics SB RAS have developed and tested a series of autonomous seismic stations. These stations, created by Novosibirsk specialists, are designed for engineering and geological surveys of ground and underground facilities in coal mines, the press service of IPGG SB RAS reported.
In the coal mining industry, performance, productivity and reliability depend on the geological structure of the area, which can complicate the process of mining and extraction of coal resources. To increase the productivity, safety and efficiency of coal mining, it is important to develop and apply geophysical methods, including various modifications of seismic exploration.
The use of autonomous seismic recorders in underground workings of Kuzbass coal mines allowed specialists to study the internal structure of the coal seam. In particular, it turned out that the main elements of its structure are local zones of increased and decreased density.
The research revealed that the structure of coal seams consists of local zones with increased and decreased density. Under certain conditions, cells of compaction and decompression are formed in these seams. This affects the formation of coal methane traps, and scientists also found out how exactly they are formed.
Innopolis University, together with PRIN company and engineers from MosgorGeotrest, conducted the first test of an industrial unmanned drone in the mines of the Moscow Metro. This unique device is designed for monitoring complex objects, such as mines, tunnels and collectors, where manual work is dangerous for people.
