It consists of selected material from the out-of-print industry standard, …
The selection of underground mining methods is primarily based on the geological/spatial setting of the deposit. Candidate methods can therefore be chosen and ranked based on estimated operational/capital costs, production rates, availability of labors and materials/equipments, and environmental considerations.
The appearance of new surveying instrument which fit to mine surveying (e.g. automatic observa-tion gyro theodolite, single degree of freedom gyro- scope) [1] makes mining survey steps into a new period, that makes mining survey work toward to efficient, intelligent and automatic development direction. 2 The application of spatial information ...
4.3 Evolution in Instrumentation and Methods for Mining Surveys Mining surveys require adequate instrumentation to effectively address both surface and underground assignments. A gyrotheodolite is used for …
The invention of gyro-attachment has helped in overcoming the above difficulties. Fig. 7. Gyrotheodlite Gyrotheodlite is a surveying instrument used to orientate an underground survey base line relative to true North. The Instrument is used to find the bearing of any line on the surface or in the underground.

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 …
Here at Merrett Survey we have provided mining clients with area-wide lidar to help them in their exploration work. With high accuracy digital terrain models (DTM) generated from our aerial and ground based mine surveying services, clients can map their prospect areas in detail, plot their geological data, merge in existing borehole data, compare the inferred …
Mining survey is the process of collecting data about the mineral resources present in a particular area. The data collected is used to make informed decisions about mining operations in the area. Mining survey is an important part of the mining process. It helps companies to identify the locations where they can extract coal, oil or other ...
About one quarter of the coal produced in Australia is by underground mining methods. The most commonly used underground coal mining methods in Australia are longwall, and room and pillar. This paper provides a detailed review of the two methods, including their advantages and disadvantages, the major geotechnical and …
The surveying system layout together with an image of the probe is depicted in Fig. 3 and its deployment in an underground mine is illustrated in Fig. 4.The surveying system consists of: a probe to measure azimuth and dip angles (its main characteristics are shown in Table 2); a cabled charging hose to move the probe along …

1. Introduction. Historically, mining mainly focused on prospecting, exploring and exploiting surface and near-surface (shallow) mineral deposits, which have become hard to find, exhausted and/or are undesirable for extraction due to limited geological confidence, socio-environmental concerns, geotechnical issues, and/or economic …
Aerial photography, ground photography, plate survey, and other methods are used to map topographic maps and other mining maps on a scale of 1:1,000 to 1:500. The coordinates in surface and underground of mines must be unified, and the earth-fixed axis system is transferred to the underground by orientation and induction height.
