Sampling Methods MINING

2021-4-13  CHIP SAMPLING. This method is used to take samples from an outcrop. The tools are used hammer and chisel. Samples taken at the surface fresh and clean. This method is used only in a preliminary investigation. The results are unrepresentative of the actual state of mineralization. Chip sampling in underground mines:

CHAPTER An Evaluation of Sampling Methods for Data

2005-2-9  SAMPLING METHODS The sampling methods studied include simple random sampling, systematic sampling, and stratified sampling. Simple random sampling selects n samples tuple-by -tuple from a population of size N by drawing random numbers between 1 and N . Denote the population of N tuples as the focusing input, F in, and the selected samples

Ore Sampling Methods: Good & Proper 911

2017-2-22  Grab-sampling by an interested party, at its best, is only a prejudiced conjecture, while at its worst it gives rise to the most unscrupulous practices with which the ore-producer and the mining-investor have to deal. Shovel-sampling, another archaic method which is still used in some localities, consists in throwing out from the car or wagon every third, fifth, or tenth shovelful for a sample.

2014-8-2  Sampling is defined as taking a small portion of a whole mass that accurately represents the whole mass. Very simple to define, however obtaining a representative sample is anything but simple. Mathematicians will say sampling is expressible as a series of mathematical equations. Such as, for sampling "X" pounds of material, one would take "y"
