【摘要】 本文首先应用实际地质资料阐述了钻孔资料稀少区域的地震反射波地质层位涵义标定方法;然后应用实际资料对提高煤层底板深度精度的时深转换方法进行详细说明,经过钻探与巷道资料验证,证明了正演模拟技术能够正确指导地质层位标定、叠加速度体的充分利用能够有效提高底板标高精度。更多还原

【Abstract】 This paper firstly uses actual geological data to state the calibration method for corresponding geological layer meaning with the seismic reflection in the region of few boreholes.Then it gives the details that combining real geological data with time-depth conversion can improve the depth accuracy of coal floor.The verification of real drilling and roadway data proves that forward simulation techniques can conduct the calibration for geological horizon correctly and the full utilization of staking velocity volume can effectively improve the depth precision of coal floor.更多还原
