Why UCG?
Lower operational costs then conventional mining
Mining cost
Surface area
Transportation and storage
Refuse disposal
No surface gasification
Safety issues in mining
Unminable coal deposits
Climate protection (controlled CO2 ,NOx, SOx)

Clean Coal Technologies
Can Poland be the Leader?
Potential
Poland is one of the richest coal-per-capita country in
the world
Poland has a tradition of mining and coal geology R&D
and industry
Need
Poland needs to reduce dependence on fuel imports
Polish electricity is some 80% coal-based
Clean Coal Technologies
Can Poland be the Leader?
Key Steps
Embrace Clean Coal as national R&D strategic program
Embark on massive R&D in the UCG area
Embark on pilot plant construction
Challenges
Committment of significant resources
Being among the first is essential

Dr. inŜ. Bohdan śakiewicz
Expert in deep mining and mining geology
Early 1960’s UC Processing trials
Leader in the development of numerous new mining
technologies in Poland and in the United States
Was the lead engineer and project director in the design,
construction, and operation of numerous international
projects
Was successfully engaged in commercial business of oil
production from marginal fields in the US
During 50 years of his professional career has received
numerous high prizes and awards including the Diamond
Crown of the International Quality Summit

UCP – Advantages of PLRT Method
Extraction of over 80% of coal thermal and chemical
value without cost and risk of mining
Reduction in CO2 production through partial chemical
re-processing and through sequestration
Unique method of “pre-processing” of the coal through
shattering with propellants and continous re-agitation
Segmental processing with high level of process control
retained at all time
Cross section of SDS
equipped with
multifunction, small
diameter Jet Stingers,
which can cover area of
up to 15 sq. km
Super Daisy Shaft’s drilling

Konsumpcja paliwa węglowego w UE – 25 (2005 r.)
Z prawie aktualnej „Polityki energetycznej”
wynika, Ŝe w Polsce naleŜy oddawać co
roku elektrownie o mocy 1000 MW
albo co 5 lat nową elektrownię o mocy
4-5 tys. MW
Według ostatnich danych przyrost
moŜe być jeszcze większy
