workings of a mining or quarrying operation. Other plans may be required as set out in Section 3.10. There is also a need to keep a survey book in the survey office. This book should be in hard copy and should comply with requirements of section 89 of the Act. This does not prevent the same information being stored in electronic form in addition to
Jun 07, 2020 In underground workings traversing techniques remain the same as above ground. The conditions are physically more difficult its dark, often cramped for space, there are shorter observation lines, the need for more control points, the types of control point installation, continuous mine working activity.
1.2. Open Pit vs. Underground Mining Methods While most mineral deposits can be mined by either surface or underground methods, some minerals can only be recovered in a hybrid manner, usually by initial extracted by open pit mining, followed by underground methods. Here, a brief comparison is made
The Miner Operated Survey System (MOSS) underground surveying software supports a wide range of Leica robotic total stations, including the latest jumbo drill steel layout system and state-of-the-art MS60 3D face mapping technology. Developed by Northern Survey Supply (NSS), MOSS incorporates a robotic total station to control layout activities ...
Horizontal distances may be determined by many methods. The survey tape is the most common, but other methods and devices are also used in highway work. - Pacing Count the number of steps and multiply by the known length of each step. This is used to provide distance estimates when no measuring device is available or precision is not required.

Jan 12, 2018 Surveying in the mining industry, both in open-pit and underground mines, often goes hand in hand with terrestrial laser scanning (TLS), which is deployed to verify the spatial changes of mining works. Thanks to its high point density and high accuracy, TLS is a very suitable surveying technique for monitoring movements and deformations.

Sep 29, 2000 One of the first differences a new surveyor underground notices is the fact that all the survey points are overhead. Because of the mud and the constant traffic of mining equipment, it is not practical to set points in the bottom of the seam. Surveys are generally run on the centerline of the mine areas.

Total Stations. Total stations are one of the most common surveying tools used today. They comprise of an electronic theodolite and an electronic distance metre/measurement (EDM) component. Robotic total stations are also available which allow for single-person operation by controlling the instrument using a remote control.
