    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. Principle of Gyro The gyro attachment consists of a gyro motor suspended vertically, like a plumb bob on a thin metal tape.

    Instruments for surveying underground cavities are internal tachymeters, the sectograph, ultrasonic instruments such as the Luch station, and sonar. Dipping compasses are used for surveying boreholes. Among the instruments used for office work are planimeters, pantographs, photocopying devices, drawing tools, calculators, and Drobyshev rules.

    What is Underground Surveying? Underground surveying embraces the survey operations performed beneath the surface of the earth in connection with tunneling, exploration and construction in subterranean passageways. It is quite different from surveying on the surface. The following peculiarities of underground surveys

    29.09.2000· Underground mine surveyors need most of the same stuff, but that is only the beginning. Every surveyor underground wears a miner’s hardhat and a wide leather belt that holds a self-rescuer to supply oxygen in case of emergency, plus a heavy battery connected by a cable to an electric lamp on the hardhat. Each crew carries a hand brace and drill bits as well as a heavy-duty, battery-powered

    underground mapping and, thus, to mining engineering. Mining is an ancient practice, though mines as extensive and deep as those in the anthracite region are more modern inventions. Mine mapping, in one form or another, is almost as old a practice as mining itself. The mining industry had long used ordinary land-surveying techniques to map the property boundaries of mines above ground and

    Underground surveying is quite different from surveying on the surface. In tunnelling or mining operations it may be hot, wet, dark, cramped, dusty, dirty and dangerous, and usually most of these. The essential problem in underground surveying is that of orientating the underground surveys to the

  • Safer survey of alignment in underground mining

    Underground mine surveying are projects where the surveyor is required firstly, to produce profile points and markings to assist the miners in drilling and blasting, and also for the monitoring of certain problem areas and finally, to supply data to calculate volumes that will be used for progress reports and planning.

The need to include the survey discipline from the outset of the project has risen as key to the successful delivery of a quality project. Survey errors and delays can have significant safety, schedule and cost impacts. Survey should always be considered in the “planning and design” phases. This will be dealt

  • Types of Land Surveying Utilized by Mining Operations

    Often used to help find underground resources, as the name suggests, mining surveys are used to scope out potential mining locations. Using surveying minimizes the risk that potential mining sites may not contain resources. Mining surveys are also used to provide information about mine and tunnel dimensions. This important information greatly impacts the safety of miners and the industry. In

    two basic methods of extracting coal, i.e. surface mining and underground mining, are introduced. Firstly, two main methods—strip mining and open-pit mining—of surface mining are discussed. In underground mining, room and pillar, shortwall, and longwall mining methods are introduced. Finally, a brief prospect for coal exploration and mining
