Surveying in the Mining Sector | GIM International
12/01/2018· Mine Surveying Today. Mining surveying can be summarised as ‘the digging of mine shafts and galleries and the calculation of volume of rock’, although it entails much more than this in practice. Geometric constraints – e.g. vertical shafts and narrow passages – demand the use of specific survey techniques. While the basic principles of surveying may have remained largely unchanged throughout the ages, the instruments used have not. Common technologies in mine surveyingThe role of seismic surveying in coal mining exploration,,01/08/1984· The quality of surface seismic reflection surveying has steadily im- proved and within the last ten years it has been applied to coal mining with increasing confidence. It was seen that if seismic reflec- tion techniques could be applied from under- ground to search for faults in front of coal faces then these faces would have predictable lives and the benefits of expensive mechanisa- tion would be far greater. The National CoalThe role of seismic surveying in coal mining exploration,,The use of both high resolution surface seismic reflection surveys and in-seam seismic techniques in the exploration of coal is described in this paper. In the past, the traditional method for exploration for coal was by means of vertical boreholes both on land and offshore. This has now been augmented by the development and application of new high resolution surface seismic techniques to give valuable information on the geological structure for both new mineMine Surveyor.net - Mining Basics - Open Cut Coal,Coal Mining. Once coal has been uncovered by either an excavator or dragline, an excavator and truck combination are used to mine the coal. To ensure coal is mined optimally as well as accurate reconciliations, surveyors complete a pickup of both the top of the coal (roof) and once removed, the bottom of the coal (floor). Therefore it is usually a good practice to remove the overburden from above the coal prior to digging the coal.

A fault of throw greater than a seam thickness of about 3 m can cause enormous delays to mine production. BHP Coal has been using 2D seismic surveying for some time to map structures with throws down to about 5 or 6 m but in an effort to obtain better resolution (mainly through seismic coverage), 3D seismic surveys
the place of engineering surveying in coal mining
National Diploma in Mine Surveying/Advanced Survey Certificate, in Mine Surveying • A minimum of 10 years' Coal Mining experience, short- and medium-term mine planning and engineering surveys.Underground Surveying,29/09/2000· In the low coal mines, coal is moved by low profile conveyor belts. In transportation areas, the roof is blasted higher than the seam, and at conveyor belt headers and other key locations, rock is removed to provide room to stand and work. The ideal height of a coal seam is around 7', which permits walking upright while being able to reach the roof. Anything much less or much more presents problems for the workers. One of the first differences a new surveyorSurveying | Coal Mining Terms Dictionary | The Coal,(1) The process of data collection by observation and measurement.

If the coal seam or strata is thick enough to stand on, it is usually called high coal; if not, it is called low coal. In the low coal mines, coal is moved by low profile conveyor belts. In transportation areas, the roof is blasted higher than the seam, and,underground mining surveying techniques instruments,Longwall mining is a highly mechaniz ed underground mining sys tem for mining coal.
