【摘要】 为了研究煤层动力学参数与煤层瓦斯地质参数之间的相关关系,采用矿井震波探测技术对淮南新庄孜煤矿主采煤层进行了震波衰减探测试验,分析研究煤层的吸收衰减系数和煤层品质因子Q值特征。试验结果表明:试验区煤层瓦斯压力与Q值成幂函数相关、瓦斯含量与Q值成近似负线性相关;衰减系数与瓦斯压力成正线性相关,与瓦斯含量成指数函数相关。研究结果为煤与瓦斯突出预测提供了新的参数。更多还原

【Abstract】 In order to study the relationship between the seismic dynamics parameters and geological parameters of coal seam and gas,seismic wave predicting technology is adopted to conduct the attenuation experiment at Xinzhuangzi Mine in Huainan area,and attenuation characteristic and quality factor are discussed.The result of the test indicates that gas pressure of coal seams has a exponential correlation with Q value,gas content has a approximately minus linear correlation with Q value,gas pressure has a plus linear correlation with attenuation coefficient,and the gas content has a index correlation with the attenuation coefficient in this area.The result offered new parameters for coal and gas outburst forecast.更多还原
