Sonic sampling for mining Eijkelkamp SonicSampDrill

Sampling activities for mining are often negatively influenced by the generally poor quality of samples you obtain with traditional drilling techniques. Slow advancement of the drill results in your field specialists wasting their time, and a drill grid that is insufficiently explored. Because of poor engineering data due to bad sample quality, high costs will occur in the long run. Our answer

A Few Methods for Sampling Hardrock Deposits June

With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment to proceed with small-scale mining or other options. Early in life, I was fortunate enough to have a friend who was a geologist, with a mindset for prospecting, who was willing to show me some of the basics of sampling in the field.

Evaluation of Sampling for Data Mining of Association Rules

Random sampling for data mining Random sampling is a method of selecting N units out of a total Y, such that every one of the Z[] distinct samples has an equal chance of being selected. In this paper we consider sequential random sampling without replacement, i.e., the records are selected in the same order as they appear in the database, and a drawn record is removed from further
