Measuring Methods for Cross Sections of Underground Mine Chambers
It is necessary to control form and size of cross sections at underground mine chambers both at the stage of chamber construction as well as periodically during its utilization. Deviation from design size or reduction of the section due to rock pressures may have very negative economic and safety consequences. Measuring of cross sections is performed by methods based on the application of classic instruments and tools, as well on the application of laser devices. This paper shows some of the most commonly used methods for measuring cross sections of underground mine chambers.
