In order to theoretically explain the mechanism of induced ground pressure and propose solutions,theoretical research was conducted to address the lack of understanding of the mechanism and the absence of deeper theoretical basis for specific engineering measures.The study simulated on-site water injection and pressure relief projects by altering the moisture content of the rock,and analyzed the changes in the mechanical properties of the rock.The experimental results showed that conventional pressure relief measures meet the concept of preventing induced ground pressure.The applicable conditions and optimal states of existing warning methods were reviewed,and the external factors leading to warning failures were explained.For example,due to the special structure of the rock,both natural and saturated states meet the conditions under water injection and pressure relief,while the dry state does not meet the conditions,making it difficult to accurately detect pre-disaster signals and predict rock failure.The rock near the deep working face underground tends to have lower water content due to the development of pores and fractures,as well as the influence of self-weight or mining disturbances,making prediction and prevention challenging.This has a significant impact on controlling the parameters of water injection and pressure relief.The analysis results can provide a theoretical basis for improving the accuracy of induced ground pressure warning.
