摘要

PROBLEM TO BE SOLVED: To provide a method for exploring and a method for confirming bedrocks in front of a cutting face, whereby the explored result of the bedrocks in front of the cutting face and a state of the cutting face can be confirmed almost real time at an office or the like. ;SOLUTION: Reflecting waves of seismic waves by blasting, oil pressure data and inclination data of a wheel jumbo 4 when drilling, and images of a cutting face 101 which are measured to explore bedrocks are transmitted to an analyzing apparatus 201 in an office 200 outside a tunnel through PHS communication devices 2a, 3a, and 44 and a PHS antenna 1. The analyzed result and various data outputted from the analyzing apparatus 201 can be utilized over the Internet.;COPYRIGHT: (C)2001,JPO
