Mining Geology Sampling Methods: Channel, Chips, Core
The mineral value in itself may be of secondary concern where sampling or examination of the lands for example, show unfavorable bedrock conditions, excessive amounts of sticky clay, large boulders or other factors that would adversely affect a placer mining operation A good sampling program will provide the information needed to evaluateMining Influenced Water (MIW) Not limited to low pH Allows for characteristics other than low pH Elevated Fe and/or Al concentrations, elevated nonFe/Al metal concentrations, elevated sulfate concentrations, elevated total suspended solids Each requires a different approach to sampling, monitoring, and control Characteristics are a function of geology/mineralogy,Sampling Considerations at Mining Sites—expanded version
Core sampling | mining | Britannica
Core sampling, technique used in underground or undersea exploration and prospecting A core sample is a roughly cylindrical piece of subsurface material removed by a special drill and brought to the surface for examination Such a sample is needed to ascertain bulk properties of underground rock,Data sampling is a statistical analysis technique used to select, manipulate and analyze a representative subset of data points in order to identify patterns and trends in the larger data set being examinedWhat is data sampling? Definition from WhatIs
Mining Wikipedia
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer depositThese deposits form a mineralized package that is of economic interest to the miner Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and claySampling 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 exploredSonic sampling for mining Eijkelkamp SonicSampDrill
Sampling Methods | MINING
At a hydrothermal sediment mined by underground mining systems, channels made from hanging wall to foot wall Application of existing methods must be accompanied by an appropriate design Some examples of chip sampling and channel sampling in the field application are as follows: 4a Channel sampling in test wells Used for the sediment surface• data mining as a part of the “Business Intelligence Cycle” • sampling as a valid and frequentlyused practice for statistical analyses • sampling as a best practice in data mining • a data mining case study that relies on sampling For those who want to study further the topics of data mining and the use of samplingData Mining and the Case for Sampling
