INTRODUCTION .
Inthefuture theCommunity 'senergy supply will .have todepend more and
more strongly ontheuse ofcoal .This will require considerable efforts
tomaintain orincrease production capacity either bytheenlargement
ofexisting mines orbythedevelopment ofnewones ..TheCommunity 'smining
undertakings will ,particularly asaresult ofthenecessary extension to
increased depths ,consequently befaced with scientific andtechnical problems
that cannotbesolved without further intensive research anddevelopment .
Onthese grounds theCommission proposes theapproval ofaCommunity research
programme inthefield ofmining engineering that will becarried outinclose
cooperation bythefollowing institutions andundertakings :
-TheNational Coal Board ,London ,(NCE)
–TheSteinkohlenbergbauverein ,Essen (st3V )
–TheCentre d'Etudes etRecherches desCharbonnages deFrance ,Paris (CERCHaR /
–TheWestfälische Berggewerks schaf' tskasse ,Bochum ,(WBK )
andforwhich financial aidunder theterms ofArt.55§2c)oftheE.C.S.C.
Treaty hasbeen recueated .

AIMS AJID OBJECTIVES OFTHE PROGRAMME
Theaims ofthis newprogramme maybesummarized ,asfollows :
Worki _n£environment andsafety
Problems arecaused particularly inthis area byextension togreater depths
forwhose solution suitable means .must befound .Only theincreased 'rate
of .methane emission ,theincreasing temperature andthehigher rock pressure
need bementioned here .Inaddition ,attention must begiven tofurther
mechanization andautomation inallunderground operations inorder tomake
work places ;more -attractive .
Teconique s < \
mpreparatory work ,the aim should betoincrease the application of
mechanized roadway drivage ,with all itsadvantages .Inthefield of
ccal winning ,itisdesirable todevelop efficient systems forextreme
seam conditions anatooptimise further theexisting high performance
methods . ' -
t
further developments are essential inconnection with transport and supply
systems since there isroom here for still more rationalization .
The sane istrue for the field ofmanagement ofoperations ,where trouble -
free working with maximum safety andreduced costs canbeassured only bythe
application ofmodern techniques ofcommunication anddata collection and ^
evaluation . ■. ' 1

CONCERNING ACQMMLTUITY COAL RESEARCH PROGRAMME INTHE FIELD
OFPRODUCT BENBFICIATION WITH AVIEW TOOBTAINING FINANCIAL AID
UNDER THETERMS OFARTICLE 55§2c)OFTHEE.C.S.C. TREATY
(Budgetary year 1981 )
GENERAL REMARKS „
The renewed interest ,incoal that has arisen asaresult ofdifficulties
anduncertainties with regard toother energy sources gives anewemphasis
tothe need for continued and intensified efforts inthe field ofcoal
research anddevelopment inorder toensure that coal canbemined safely
andefficiently andthat itcanbeupgraded andused aseffectively as
possible .
I
Research related tocoal beneficiationmust beaimed ,first ofall ,at
ensuring that coal users canbesupplied with aproduct ofhigh andconsis
quality ,suited totheir requirements .Other important topics inthis fiel
include improvement ofthetechnology andeconomy ofmetallurgical coke
manufacture ,amatter ofvital importance totheCommunity steel industry ,
andtheconversion ofcoal tohigh value products ,notably liquid fuels an
*
feedstocks fortheorganic chemical industry which canbe 1used assub­
stitutes forproducts derived from oil .Inaddition ,further research is
needed ontheupgrading ofcolliery spoil inorder toalleviate the
Community coal mining industry 'sproblems over thedisposal ofthat
material . -

On_these grounds theCommission proposes theapproval ofaCommunity research
programme inthefield ofproduct beneficiatiaifor which financial aidunder
theterms ofArt.55§2c)oftheE.C.S.C. Treaty hasbeen requested and
which will becarried jOutinclose cooperation bythefollowing institutions

~TheSteinkohleribergbauverein ,Essen (StBV )
-TheUniversité Libre deBruxelles (ULBV . ■
Theallocation oftasks within theprogramme takes account ofthefacilities
vandexpertise existing inthevarious Community countries andcollaboration
between research workers and coal producers isassured .
II.AIMS ANDOBJECTIVES OF .THEPROGRAMME < '
Theresearch projects inthefield ofproduct bene ficiationforwhich aidis
requested arerelated tofour main topics andthus form four programmes :
.-Mechanical coal preparation and coal transport
-Coking of"coal
-Combustion ofcoal andnewtechnologies forcoal utilization ,and
-Coal chemistry andphysics anddevelopment ofprocesses
Thequantity offine material inrawcoal increases asmore powerful coal
winning machines arebrought into operation .Theprogramme onmechanical coal
preparation aridcoal transport therefore includes projects aimed atimproving
thecleaning ,sizing andfiltration offines .Asnewtechnologies ,such as

gasification and .liquefaction ,areintroduced ,inthefuture ,coal quality
*■ ,
requirements will change ,andthere islikely tobeaneed forimproved
consistency ofcoal quality .The progr'aaime takes these needs into consideration
andalso includes work aimed atmaking themost efficient use ofavailable
equipment bymeans oftests onfull-^izeunits .
Inthefield ofcoking ofcoal thegeneral aims ofCommunity research
include increasing thecapacity andprofitability ofcoke ovens ,widening
thecoking coal range ,maintaining andimproving coke quality andsolving
problems ofpollution .There isastrong interest inimproving theassessment
ofmetallurgical coke quality and ,with this endinview ,aproject onthe
testing ofcoke under simulated blast furnace conditions isincluded inthe
*
research programme .Theprogramme' also includes projects directed towards the
automation ofcoke oven operation ,thereduction ofenergy consumption ,in­
creasing theyield ofsaleable coke ,using' larger proportions ofpoorly -
coking coal ,andimproving thespecification ofoven refractories toreduce
therisk ofexpensive damage . '
The programme oncombustion ofcoal andnew technologies for coal utilization
comprises asingle project whose aimistofind newuses forcolliery spoil
with aview toreducing theenvironmental andother problems associated with
spoil dumping .
Theprogramme oncoal chemistry andphysics ,anddevelopment ofprocesses
includes aproject related tothemanufacture ofhigh value materials
from carbonization by-products ,andaseries ofprojects covering awide
range offundamental research related totheupgrading ofcoal products
andby-products ,liquefaction ,combustion andcarbonization ,whose purpose
istoserve asafoundation fortheimprovement ofexisting processes and
thedevelopment ofnew ones .

VI.EXPECTED REPERCUSSIONS OFTHE RESEARCH PROGRAMME
■Theresearch programme will contribute totheefficiency ,andeconomy
of 'coal preparation "byfacilitating the correct selection ofequipment
and .improving methods of,treatment ,especially offine material .Iiwill
'"also help coal preparation plants toadapt tochanges inboth thequality
. \
oftheraw coal and therequirements ofcoal userso .■ 1
Inthefield ofcoking ofcoal theresearch work will lead toimprovements
ι· ' ' ι
inoven operation that will have favourable effects ontheeconomy ofthe
industry (through improvements inyield ,reduced energy consumption ,the
useofcheaper coals ,etc.).Thestudies directed towards partial automation
;are alsoexpected tolead toreduced pollution andanimprovement inthe ,
.wdrking environment .Thedevelopment ofcoke quality assessment will beof
value totheCotmiunity steel industry by .virtue ofthecontribution that
,itwill make totheimproved ,specification ofcoke andtheefficiency of
•blast furnace operation .
Theproject forming theprogramme oncombustion ofcoal andnewtechnologies
forcoal utilization will contribute towards theprovision ofoutlets for
spoil-based materials andwill consequently help to'reduce theneed for
•spoil dumping with ,itsassociated cost ,environmental and space problems .
Theprogramme oncoal chemistry andphysics anddevelopment ofprocesses
.will provide avaluable back-up forthedevelopment -ofnewprocesses that
.canbeapplied industrially andtheimprovement ofexisting processes ,and
wili contribute especially totheproduction ofcoal-based substitutes for
oilandoilproducts .* v •" , ' .
VII.' COriCLUSTOUS
Forthereasons outlined above ,theprovision offinancial aidbythe
Community for*theproposed research work inthefields ofmechanical coal '
preparation and'coal transport ,coking ofcoal ,combustion ofcoal and
newtechniques forcoal utilization ,andcoal chemistry andphysics and \
development ofprocesses isjudged tobeappropriate andjustified . r
