Ministry of Energy and Coal Industry of Ukraine has developed
Coal Industry Development Program Until 2030, which sets an
objective of increasing coal production by 1.5 times to 2030,
from 85 Mt to 125 Mt. Currently the program is being
considered by the Cabinet of Ministers of Ukraine

Coal production from Ukrainian mines has grown steadily over
the recent years. In 2012 level of production totaled 85.7Mt.
Production from the mines which are not owned by the state is
increasing with each year and now accounts for 71%
in total coal production balance, while that from
state-owned mines – for 21%

Coal Industry Development Program Until 2030 determines a
direction to further reduction of state share in coal mining and
transfer of coal mines to private ownership, leasing or concession.
Thus, over the last two years the number of private mines has
grown by 36% (from 29 to 45), and number of state-owned ones has
reduced by 13% (from 127 to 110)

Coal in Ukraine is produced by 155 large mines, including 142 (91%) in
methane-reach coal seams (for 30 mines absolute methane emissions are
between 0.5 and 12 m3/min, and for 112 – higher than 12 m3/min and with
potential for spontaneous outbursts). These mines in 2012 produced more
than 60 Mt of coal (68% of total production)

Volume of methane emissions from mines is about 1400 million m3/year.
Coal production process is accompanied by natural methane gas emissions
into mine ventilation system in approximate amount of 1000 million m3/year.
Degasification recovers 370 million m3/year, or about 25% of total methane
emissions

Today degasification is performed at 44 mines with production of
39.1 Mt of coal (46% of total production in Ukraine), including 18
mines not owned by the state, with annual production at 28.6 Mt,
and 26 state mines with annual production at 10.5 Mt

Only for 18 mines of 44 mines that perform degasification,
methane content in the mixture exceeds 25%, while for 26
mines it is less than 25%, which prevents further use of
methane

According to Safety Rules, coal
mines are prohibited from using
methane-air mixture if methane
content is less than 25%

LEGISLATIVE AND NORMATIVE ACTS
THAT REGULATE PRODUCTION,
DEGASIFICATION AND UTILIZATION OF COAL
MINE METHANE GAS
Code of Ukraine «About the subsoil» (from 27.07.1994
from 16-10-2012);
Law of Ukraine «On coalbed methane»
(from 21.05.2009 );
Law of Ukraine «On Alternative energy sources»
(from 20.02.2003);
Tax Code of Ukraine (from 01.04.2012 );
Coal Mine Safety Rules (from 22.03.2010 ).
Insufficient level of both degasification and further utilization of
gas methane is determined by the following reasons:
1. Lack of proven technologies for preliminary coalbed degasification by
means of surface-based drilling and hydraulic fracturing.
2. Low storage capacity of coal-surrounding rocks. Permeability of sandstones
is less than 0.1 mD (millidarcy), porosity of sandstones is on average 5-6%.
3. Low production speed in mine faces (less than 1000 tones/day), leading to
slow mine face progress.
4. Insufficient use of advanced technologies and equipment for underground
degasification.
5. Inadequate capacity of the majority of mine degasification systems due to
low pipeline diameters (250 – 350 mm).
6. Lack of operating degasification control equipment needed for maintaining
degasification parameters, first of all, methane content (higher than 25%) and
production rate.
7. Gaps in legislative and regulatory acts related to promotion of investments
and preferential taxation.
Lower number of accidents and improved labor safety for miners;
Greater use of alternative fuels;
Improved basis for coal production growth;
Established opportunity for getting cheaper electricity and heat by
mines;
Additional financial resources as a result of joint activities of mines
(mining companies) and investors in the area of degasification and
utilization of coal mine methane;
Significant reduction of greenhouse gas emissions;
Additional employment.
EXPECTED RESULTS
from implementation of methane degasification
and utilization projects in Ukraine:
