==Great Library entry==
Mining technology reached its zenith in the late 27th century with the development of fully automated deep-core drilling machinery. The new mega mines utilized advanced gravimetric sounding equipment and were directed by powerful artificial intelligence algorithms originally developed by the military. While tough on the environment, a fully operational mega mine is capable of locating and excavating vast mineral reserves in an astoundingly short period of time.
