The invention relates to an in-hole
seismic wave based advanced prediction method. The in-hole
seismic wave based advanced prediction method comprises the following steps that 1, an in-hole excitation probe and a receiving probe are synchronously pushed to the bottom of a
drill hole; 2, a hole is filled with water by using a water
injection device and is sealed by using a rubber plug; 3, detection is performed by adopting in-hole exciting seismic
waves and hole orifice exciting seismic
waves; 4,
data processing and interpretation and result output are performed. The in-hole
seismic wave based advanced prediction method is a novel advanced prediction means, can visually and accurately detect structural anomaly within a certain range of the periphery of the hole
diameter in virtue of the advantages of in-hole common-offset seismic records in a close-range mode, can obtain the rock
mass characteristics of surrounding rocks in a close-range mode, can utilize the seismic records obtained through hole orifice common-source point excitation to obtain a more accurate
longitudinal wave speed value, can decrease report omission phenomena during drilling, can obtain more accurate speed information compared with other advanced
earthquake prediction methods and can more accurately provide advanced tunnel prediction results. The prediction results provide powerful references for construction decision makers to decide to increase the number of
drill holes or not and adopt which excavation ways.
