Data loggers will be placed in the boreholes to provide time series data on changing water levels. The data will be downloaded and samples taken from the boreholes approximately every 3 months. Some twig samples may be taken from trees close to boreholes for isotope analysis to confirm the source of the water and to estimate the depth of the.

Geophysical, borehole and mapped data from the Kalahari Basin were used to create maps of the sub-Kalahari geology, isopachs of the Kalahari Group and basal gravels and a sub-Kalahari topographical surface.

These are the first basin-wide maps of this type to be produced. These newCited by: T he W itwatersrand has been the main source of world gold throughout the twentieth century, and in many of these years it has accounted for more than half of the world's gold production (Fig. 1).A total of 48, tonnes of gold has been produced since the discovery of these gold fields in Uranium has been a very important byproduct of gold mining since ; the cumulative production of.

A technique is described for developing an on-line instrument measuring the ash content of coal in a coal washery tailings stream. The method employs two radioisotope-detector systems, a Cs density transmission gauge and a Compton backscatter x-ray gauge with Cd.

To evaluate the technique under typical plant conditions, a full-scale slurry measuring loop was constructed. In addition a real SCPT data tomographic data set is presented using SCPT seismic data that was acquired at offsets of m, 5 m and 10 m, and down to a depth of m.

In mineral resource estimation, identification of the geological domains to be used for modeling, and the type of boundaries dividing them, is a major concern.

Generally, the variables within a domain are estimated with an assumption of the hard boundaries (sharp contact). However, in many cases, the geologic structures that generate a deposit are transitional (overlapping of several geologic Cited by: 2.

At the bottom of the page the time consumed in drilling, pulling, moving, repairs, and delays is recorded. The geophone VSP data were acquired with a very small geophone spacing of m in borehole KU, which provides shot records of high resolution.

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies.

Soft rock mining refers to excavation of softer minerals such as salt, coal. The importance of data gathering was reiterated once more at the 12 th INDEPTH Scientific Conference, held from 28 to 31 October at the Wits School of Public Health.
