煤矿矿震应力波传播衰减理论模型及应用研究
A theoretical model of stress wave propagation attenuation in mining-induced seismicity and field application
摘要
Abstract
The attenuation behavior of seismic wave propagation during mining-induced seismicity is fundamental for accurately assessing its disaster potential.This study investigates the vibration characteristics of mining-induced seismicity in coal mines and develops a theoretical framework for assessing seismic risks.A theoretical model of seismic wave attenuation in mining-induced seismicity is developed,incorporating geometric attenuation coefficients,material attenuation coefficients,and the influence of in-situ stress.Taking the Shilawusu Coal Mine as a representative case,this study systematically quantifies the attenuation coefficients of strata materials through a combination of laboratory experimentation and field monitoring.Additionally,it rigorously evaluates the influence of in-situ stress on the attenuation dynamics of mining-induced seismicity and formulates a propagation attenuation model specifically tailored to its characteristics in the Shilawusu Coal Mine.Subsequently,with the Shilawusu Coal Mine as the engineering background,this study employs a combination of laboratory experiments and field monitoring to determine the attenuation coefficients of strata materials,analyze the influence of in-situ stress on the propagation attenuation model,and construct a propagation attenuation model tailored to mining-induced seismicity in this mine.The model is further applied to estimate the seismic magnitude of mining-induced events,and its reliability is validated through field observations.The results indicate that the geometric attenuation coefficient is affected by the seismic magnitude,the diffusion of the wavefront,and the scattering of stress waves at discontinuous surfaces.The material attenuation coefficient is determined by the viscoelastic properties of the rock,the velocity model of the strata,and the frequency of stress waves induced by seismicity.In-situ stress directly influences the velocity of the strata,thereby indirectly affecting the material attenuation coefficient in the model.Based on the proposed propagation attenuation model for stress waves induced by mining-induced seismicity,the seismic magnitudes of events in the Shilawusu Coal Mine were estimated and demonstrated good agreement with the magnitude forecasts provided by the Earthquake Administration,validating the model's reliability in practical applications.Furthermore,the propagation attenuation behavior of stress waves for different seismic magnitudes was predicted using the theoretical attenuation model and the relationship between seismic magnitude and energy.These findings provide a theoretical basis for understanding the propagation attenuation laws of stress waves induced by mining-induced seismicity and offer valuable guidance for assessing seismic risks in mining operations.关键词
