Pagination or Media Count:
This is a handbook to introduce mine surveyors to the use of gyrocompass gyrotheodolite equipment. It contains a brief explanation of the principle of the gyroscope and of a pendulum type, meridian-tracking gyrocompass. Typical Soviet, Hungarian and East German mine surveying gyrocompasses are described in some detail, with instructions and examples of their use. There are brief discussions of the relative advantages and disadvantages of the various instruments. This handbook, together with the manufacturers instructions, should be adequate to enable a mine surveyor with no previous experience of these instruments to use them in orienting underground surveys.
