**煤类型自动分类器，依据国标制作。

Chinese Coal Type Automatic Classifier, made according to the Chinese standard.

How to Use? 如何使用？

请编辑'CoalData_Sample.csv'中的数据增加需要检测的煤数据，之后运行'main.py'。

煤的类型取决于'Result.csv'中一行内重复最多次的煤类型。

Please input your coal data as required in 'CoalData_Sample.csv' and run 'main.py.'

The coal type based on each criterion will be displayed in 'Result.csv.' The coal type will depend on the most frequent type shown in a row.

a 在G>85的情况下，用Y值或b值来区分肥煤、气肥煤与其他煤类，当Y>25.00 mm时，根据Vdaf的大小可划分为肥煤或气肥煤；当Y≤25.0 mm时，则根据Vdaf的大小可划分为焦煤，1/3 焦煤或气煤。

按b值划分类别时，当Vdaf≤28.0%时，b>150%的为肥煤；当Vdaf>28.0%时，b>220%的为肥煤或气肥煤。如按b值和Y值划分的类别有矛盾时，以Y值划分的类别为准。

b 对Vdaf>37.0%，G≤5的煤，再以透光率PM来区分其为长焰煤或褐煤。

c 对Vdaf>37.0%，PM>30%~50%的煤，再测Qgr,maf，如其值大于24 MJ/kg，应划分为长焰煤，否则为褐煤。

a In the case of G>85, the Y value or b value is used to separate fertilizer coal, gas fertilizer coal and other coal categories. When Y>25.00 mm, it can be classified as fertilizer coal or gas fertilizer coal according to the size of Vdaf; when Y≤25.0 mm, it can be classified as coking coal, 1/3 coking coal or gas coal according to the size of Vdaf.

When classified according to b value, when Vdaf≤28.0%, b>150% is fertilizer coal; when Vdaf>28.0%, b>220% is fertilizer coal or gas fertilizer coal. If there is a contradiction between the categories classified according to the b value and the Y value, the category classified according to the Y value shall prevail.

b For coals with Vdaf>37.0% and G≤5, the transmittance PM is used to classify them as long flame coals or lignite coals.

c For coal with Vdaf>37.0% and PM>30%~50%, then measure Qgr,maf, if the value is more than 24 MJ/kg, it should be classified as long flame coal, otherwise it is lignite coal.
