COLUMBIACANADA  \nMAY 1996  \nThis report is a compilation of coal quality data frommost of the coalfields in British Columbia.Data are fromtwo major sources:1)analyses of raw coal samples collectedat producing mines in northeast and southeast B.C.;and 2)coal assessment reports submitted by industry.Specificanalytical parameters discussed include:coal petrography(vitrinite reflectance and maceral composition);ASTMrank;proximate and ultimate analyses;calorific value;min-eral matter content;ash chemistry;phosphorus concentra-tions;trace element concentrations(Sb,As,B,Br,Cd,Cl,Cr,Co,Cu,F,Pb,Hg,Mo,Se,Th,U);and,caking power(FSI,dilation and fluidity).The focus is on raw coalsthroughout,although in certain cases clean coal data areused.  \nASTM rank for coals from both northeast(Peace River)and southeast (East Kootenay)B.C.coalfields ranges fromhigh-volatile Ato low-volatile bituminous.Mount Klappan-area coals are anthracitic.High-volatile(hv)bituminouscoals are found at Quinsam on Vancouver Island(predomi-nantly hvB),Telkwa(hvA),Tulameen(hvC/B)and BowronRiver (hvC/B).Sub-bituminous and lignitic coals are foundat Hat Creek.Coals from northeast and southeast B.C.haverelatively high concentrations of inertinite macerals(aver-age about 40%mineral matter-free),of which semifusiniteis the most common.Liptinite macerals are very scarce.Mean moisture contents(air-dried)of northeast and south-east B.C.coals are generally under 1%.Coals from lowerrank basins generally have higher moisture contents.Ashcontents of individual seams vary widely;20%ash(air-dried)is an approximate,representative mean for northeastand southeast B.C.raw coals,as well as for Comox and  \n# ABSTRACT\n\nTelkwa.Generally higher ash contents are found at MountKlappan,Bowron River,Hat Creek and Tulameen.,Volatilematter contents(dry,ash-free)in northeast and southeastcoals range from about 22 to 35%.British Columbia coals,for the most part,are classified as having low sulphurcontents.The proportion of pyritic sulphur is also low.High-rank(hvA bituminous and higher)coals have meancalorific values in the range 25 to 30 MJ/kg(air dried).  \nQuartz and kaolinite are the most common minerais inlow-temperature ashes of northeast and southeast coals.High temperature ashes of the same coals have low base-acid ratios,which translates into high CSR(coke strengthafter reaction)characteristics.Mean phosphorus concentra-tions in the major coking coal-bearing formations(rawcoals)are:Mist Mountain-0.076%;Gething-0.063%;andGates -0.042%.The main factors affecting phosphorusconcentrations are the amount of ash,and the proportion ofphosphorus-bearing accessory minerals,such as fluorapa-tite.Most trace elements(for example Sb,As,Cr,Co,Cu,  \nF,Hg,Th and U)are associated primarily with the inorganicfraction of the coal.Concentrations of six important traceelements,namely As,Br,CI,Co,Pb and Hg,are relativelylow when compared with world coal averages,and concen-trations of only one element,F,is relatively high.  \nMean and modal FSI values in raw coals
