Mining
In the mining environment, extensometers are used to measure displacements on batters/highwalls. Plotting displacement vs time enables Geotechnical engineers to determine if wall failures are imminent. For complicated failures, further equipment such as radar or laser scans are used enabling 3-dimensional and ultimately 4-dimensional analysis.

Famous quotes containing the word mining:
“Any relation to the land, the habit of tilling it, or mining it, or even hunting on it, generates the feeling of patriotism. He who keeps shop on it, or he who merely uses it as a support to his desk and ledger, or to his manufactory, values it less.”
—Ralph Waldo Emerson (1803–1882)
“It’s a mining town in lotus land.”
—F. Scott Fitzgerald (1896–1940)
“In strict science, all persons underlie the same condition of an infinite remoteness. Shall we fear to cool our love by mining for the metaphysical foundation of this elysian temple? Shall I not be as real as the things I see? If I am, I shall not fear to know them for what they are.”
—Ralph Waldo Emerson (1803–1882)
