Title:
FALSE ORE, AND ANALYSIS SYSTEM USING SAME
Document Type and Number:
WIPO Patent Application WO/2012/018118
Kind Code:
A1
Abstract:
The stress received by rocks and the behavior before and after beginning a collapse or before and after a liquefaction phenomenon occurs are accurately measured, thereby being able to have a highly precise simulation of the mechanisms behind the generation of a collapse or a liquefaction phenomenon. A false ore is provided with: a case having the average shape and size of the rocks in an ore deposit or in the ground; a strain sensor for detecting the stress acting in the positive and negative direction of each axis in a three-dimensional coordinate in which the center of the case functions as the origin; a three-axis acceleration sensor for detecting the acceleration acting in each axial direction in the three-dimensional coordinate; a vibration exciter for producing a vibration in a specific direction in the three-dimensional coordinate; and a control device for converting the detection value of each sensor into a specific vibration and outputting said vibration to the vibration exciter. An above-ground control device is provided with a vibration generator and a vibration detector. Communication is established between the false ore and the above-ground control device by means of vibration transmission, the three-dimensional position of the false ore in the ore deposit or in the ground is identified on the basis of the detection value of each sensor on the false ore, and the detection value of each sensor can be collected from above ground.
