Safety Technology for Coal Mining under High Stress Conditions
This paper explored safety techniques for coal mining under high stress conditions.Firstly,it analyzed the characteristics of high stress environments,including changes in rock mechanics,stress concentration and energy accumulation,complexity of underground environments,and dynamic changes in coalbed gases.Then,it conducted in-depth research on existing coal mining safety technologies,with a focus on rock control technology,gas monitoring and control technology,stress monitoring and control technology,as well as automation and intelligent mining technology.Finally,it focused on introducing innovative coal mining safety technologies under high stress conditions,including microseismic monitoring technology,unmanned aerial vehicle detection technology in high stress areas,high-performance support materials and technologies,and high-precision geological prediction systems.The application of these technologies has improved the safety and efficiency of coal mining,which is of great significance for the development of the coal industry.
