摘要
本文阐述了超声成像的原理和方法，实际应用证明，利用超声波扫描成像技术对覆岩破坏钻孔进行探测，可克服常规方法的不足，从而提高了勘探精度与资料的可利用性。
The principle and technique ofultrasonic im agery areexpounded herein and it is proved by practice thatthe exploration to determ ine the heightofleaking crevice belt in w recked-rock over coalseam by the technique ofultrasonic im agery in borehole can overcom e the defectofroutine m ethodes .With the resultthatthe exploring precision is im proved and the data becom e useful.
