Drilling and Sampling. An integral part of a complete site investigation is drilling and sampling activities. ConeTec offers a wide variety of truck and track mounted drill rigs equipped with modern safety and efficiency features for all drilling methods.
Soil Sampling. Soil sampling and testing is generally conducted during a Phase 2 Environmental Site Assessment ESA, to determine if subsurface contamination exists or has the potential to migrate to neighboring properties. SGS is able to assist you with the design and implementation of sampling and remediation plans depending on the extent of ...
Nov 28, 2004 The fundamental rule for correct sampling and sample processing is that all parts of the ore, concentrate or slurry being sampled must have an equal probability of being collected and becoming part of the final sample for analysis Gy 3 Pitard 4 , otherwise bias is easily introduced and the sample is not representative.

Sampling data bench by bench cannot often keep up with the production demands to mine. The last bag sample on the bench leaves for the lab but the production superintendent is ready to blast. Ive seen it so many times where mining commences before data is received. Everyone is
The Sampling 2010 Proceedings looks at the importance of adopting correct sampling and sample preparation procedures and the use of correctly designed equipment. The papers explore the vitality of correct sampling and ensuring samples submitted for analysis are representative, thereby saving companies time and costs by Getting it Right at the Outset the conference theme.
Geotechnical Investigation.

adopting selective mining techniques, increasing the cost of mining, however improving the overall project economics. The estimation of Mining Recovery and Mining Dilution requires an understanding of resource estimation, mine geology, blasting, mining equipment, mine planning, mine surveying, mineral processing and information technology.
The public reporting of Mineral Resources and Ore Reserves in Canada, Mineral Reserves must comply with various International Codes.In these there is always a requirement for the data to be appropriate for use in the estimation of tonnes and grades. This means that the collection of data should accord with sampling theory and the samples must be systematically reduced in particle size and ...

When the required sampling depth is obtained, the drill string is removed from the borehole, and the desired sampling device is lowered to the bottom of the hole. Standard guidelines for producing boreholes by this method are given by ASTM D5782, ASTM D5783, and ASTM D5876 for air, fluid, and wireline variations, respectively.
Apr 13, 2021 Peter Hepton, ground investigation engineering manager, Infrastructure, Socotec UK discusses the issue of borehole logging and borehole logs and whether they should be simply considered as a choice of facts or data that can be interpreted in different ways. From a simple record of the drilling process to a detailed geologicalgeotechnical ...
