煤岩的纵、横波速度是煤田地震勘探中不可或缺的参数。采集寺河矿区的8个煤样,通过脉冲透射法测试并拾取初至,进而得到各样品的纵、横波速度。结合实测的视密度数据分析表明:各煤样纵波速度-密度、横波速度-纵波速度之间有很好的正相关关系,进行线性拟合并得到回归公式。在煤田地震勘探中建议使用根据煤岩纵、横波速度测试结果得到的关系式。
The longitudinal and shear wave velocities of coal and rock are indispensable parameters in coalfield seismic exploration. Eight samples of coal from Sihe mining area were collected and tested by pulse transmission method and the first arrival was picked up to obtain the longitudinal and shear wave velocities of each sample. According to the measured apparent density data, it shows that there is a good positive correlation between P-wave velocity-density, S-wave velocity and P-wave velocity in each coal sample, and linear regression and regression formula are obtained. In the coalfield seismic exploration, it is suggested to use the relationship obtained from the test results of the vertical and transverse shear velocities of coal and rock.
