20、 most challenging materials to sample due to its characteristic heterogeneity. A coal seam can consist of a single stratum of one lithotype of relatively uniform maceral constitution, or more commonly, consist of a number of layers of different coal lithotypes varying in thickness and lateral extent

21、. The seam can also contain discrete layers of inorganic sediments or carbonaceous shales of varying thickness. Veins of concordant or discordant secondary mineral rock could also be present. The lithotype layers can vary considerably in hardness, texture and structure according to the nature of the

22、 coal and inorganic sediments. The inorganic layers can also thicken laterally, splitting the seam into two or more separate units which could require multiple samples.It is strongly recommended that a collaborative team including geologists, mining engineers, safety, land and laboratory professiona

23、ls review each proposed sampling program to help ensure optimal effectiveness and efficiency are obtained.The purpose of sampling coal for any resource evaluation is to predict the expected quality of the produced coal from a given locale. Therefore, the fundamental goal of each sampling effort is t

24、he collection of representative samples of the seam(s) at each sampling location. A properly executed sampling program needs to accurately define both the lateral variation in coal quality and the average quality for a specified area.After inspection of any seam, the sampler designes a sampling prog

25、ram with sufficient representative samples to define the range of expected coal quality. In variable seams it is necessary to take a number of samples to improve the representativity of sampling.In operating mines, the manager needs to be consulted and approval needs to be obtained before sampling s

26、ites are selected and sampling proceeds. Where there is no operating mine the area or tenement owner and or operator is consulted.In all sampling situations, experienced and qualified personnel will be required for supervision and to ensure that accurate records are made of location, thickness and l

27、ithotype descriptions and that all safety precautions have been addressed.Methods of sampling for physical, chemical, petrographic or utilization properties are described for the following:a) sampling from small and large diameter drill cores;b) sampling from exposed seam faces;c) sampling from tria

28、l open-cut excavations;d) sampling from underground workings.

The following methods are described:a) sampling

30、of small or large diameter holes;b) drill cuttings sampling;c) open-cut slot sampling;d) adit, drift or shaft sampling;e) pillar sampling;f) channel sampling;g) strip sampling.This document does not apply to sampling from moving streams in production or any other source of coal that is not in situ.R

36、efine the minimum size of a bulk sample.3.2channel samplesample of the coal and associated inorganic material taken by removing a vertical channel of even cross-section from the seamNote 1 to entry: Where the full section of the seam is not accessible or not required, this term can refer to a sample

37、 taken either from a specifically defined portion of the seam, or from the floor to roof as mined or exposed.3.3coal seamstratum or sequence of strata composed of coal as a significant component and significantly different in lithology to the strata above and below itNote 1 to entry: It is laterally

38、 persistent over a significant area and it will be of sufficient thickness and persistence to warrant mapping or description as an individual unit.3.4core samplecylindrical sample of the whole or part of a coal seam obtained by drilling using a coring barrelNote 1 to entry: The diameter of the core

39、can vary from 50 mm to 2 000 mm depending on the reason for which the sample is required. However, 50 mm to 200 mm is the most common core diameter range.3.5cuttings samplesample of coal chips produced from the rotary drilling of a coal seam using a non-coring bit such as a blade bit or roller bit3.

40、6pillar samplesection of a seam taken in the form of a block, or series of blocks, of coal with associated inorganic rock which, when arranged in correct vertical sequence, represent a true section of the seamNote 1 to entry: Where the full section of the seam is not accessible or not required, this

41、 term can refer to a sample taken either from a specifically defined portion of the seam, or from the floor to roof as mined or exposed.3.7plylayer of coal seam normally differing in properties from adjacent layers. Any distinctive layer maybe regarded as a ply3.8ply samplesample taken from an indiv

42、idual ply or leaf or from a series of plies or leaves of a coal seam3.9strip samplesample similar to a channel sample but smaller in cross-sectionNote 1 to entry: A single strip sample can often be regarded as being too small to guarantee that all horizons of the seam are adequately represented. How

43、ever, a number of such samples can be taken to achieve better representativity in a variable seam.2 ISO 2017 All rights reservedBS ISO 14180:2017ISO 14180:2017(E)4 Selection of sampling site4.1 Initial considerationsSampling sites where possible are chosen at random when no other information regardi

44、ng the tenement or exploration site is available. The site for sampling apart from drill holes should be chosen, as far as possible, to avoid cracks and breaks, random lenses of rock or mineral matter, or other abnormalities or irregularities in the face to be sampled. However, on occasion, the purp

45、ose may be to sample a particular mode of development of the seam section, in which case the sample should be taken at the best available site exhibiting this feature. The location of the sampling point should be recorded accurately (see Clause 6).Core sampling is usually employed for sampling coal

46、seams that are not exposed in outcrop or by mining. It is especially useful in areas which are not readily accessible as drill rigs are small enough to be located by helicopter. Sometimes, however, this method is used even though exposed faces are available. This is because it is often faster, less

47、labour-intensive, safer and more representative than pillar or strip sampling, especially if a suitable drilling rig is readily available. For example, many open-cut mines take cores of the seam to be uncovered in the next mining strip to obtain coal quality data for mine planning purposes. Coring o

48、f the uncovered coal seam by a drilling rig sitting directly on top of the coal is also common practice where detailed coal quality parameters need to be known for blending purposes or for specific cargoes where the customer may be particularly sensitive to certain coal properties or inorganic impur

49、ities.Cores can be obtained routinely in diameters ranging from 50 mm to 200 mm depending on the amount of material required for testing. It is generally advisable that, for routine sampling operations, 100 mm cores be taken as this size provides a good compromise between representativity and cost.NOTE There are risks in comparing data from different core sizes of the same coal. The determined yield values and analysis for washing coals can vary significantly. When this occurs it is recommended that the results be confirmed by very large cor
