Hydrodynamic impact in the concept of integrated development of coal-gas deposits: prevention of gas-dynamic phenomena
Year: 2026
Type: conference-paper
Abstract: This paper analyzes current safety issues in deep mining operations, including the risks of rock bursts and gas-dynamic phenomena. The study aims to analyze the implementation results of hydrodynamic impact modes designed to reduce risks and facilitate the integrated mining of coal-gas deposits. The research is based on the analysis of theoretical and mining-experimental works conducted in Ukrainian mines. It has been established that employing the “fluid injection – pressure drop” mode ensures the destruction of gas-saturated coal by a reverse impulse, initiating the process of gas-dynamic self-destruction and transferring the coal seam into a safe state. Aspects of utilizing cavitational periodic-disruptive fluid injection for hydro-impulse loosening within stress-strain zones are also discussed. New scientific and technical knowledge is proposed that allows for the effective management of the state of the coal-gas environment. It is proven that the developed technologies can be applied not only in the coal industry but also in other sectors, such as the oil and gas industry and geotechnological systems for mineral extraction. The conclusion highlights the high efficiency and versatility of the developed hydrodynamic impact methods.
