METHOD AND APPARATUS FOR DETECTING ROCK MOVEMENT |
摘要 |
A method and apparatus for detecting rock movement. The first step involves using at least one electromagnetic induction coil as a sensor. The second step involves monitoring changes in induced electromotive force in the at least one electromagnetic induction coil over a selected time interval. This new approach is based upon changes in magnetic permeability as a result of rock movement in accordance with Faraday's law of electromagnetic induction. When a plurality of these new sensors are used the speed of the rock movement may also be determined.
