dyrz~mic sampling methods, which take into account the mining tool being used and can thus give better samples. We describe dynamic schemes that observe a mining tool' s performance on training samples of in- creasing size and use these results to determine when a sample is sufficiently large.Sampling Considerations at Mining Sites—expanded version,that the final sampling frequency be determined site specifically based on the variability of critical parameters, prediction objectives and required accuracy.” Runnells et al. (1997): “Briefly, the method is based on the use of a statistical approach to determine, illustrate, and defend the adequacy of the sampling.

Advantages & Disadvantages of Sampling Method of Data
Advantages of Sampling Method. Reduce Cost. It is cheaper to collect data from a part of the whole population and is economically in advance. Greater Speed. Sampling gives more time to researcher for data collection, so it is quickly and has a lot of time for collection of inflammation.

Channel Sampling Maptek
Channel Sampling uses a compositing method to obtain the actual channel length that represents a minimum mining width. The minimum mining width in the real vein thickness direction is projected onto the channel plane to obtain a length in the channel direction. This length is then used to create an ore composite, includingSimple Random Sampling and Systematic Sampling,Estimators for systematic sampling and simple random sampling are identical; only the method of sample selected differs. Therefore, systematic sampling is used to simplify the process of selecting a sample or to ensure ideal dispersion of sample units throughout the population. Advantages:

Simple random sampling Advantages & Disadvantages
This is the basic method of sampling. In this method, numbers are assigned to every member in the study group of population. Then the sample would be selected from a table of random numbers or random selection. We have already discussed about the advantages and disadvantages of sampling in general. Given here are the advantages of Simple randomprobability What's the advantage of importance sampling,Importance sampling is a Monte Carlo integration method that can be used to estimate the expected value of a function of a random variable.The method is useful in cases where the PDF is known, but the expected value of interest is unknown (and cannot be computed analytically from the PDF).
