Coal in Ukraine is produced by 143 large mines, 133 of which (93%)
have methane-rich coal seams (30 mines have absolute methane
emissions between 0.5 and 12 m3/min, and 103 mines – over 12 m3/min
and potential for spontaneous outbursts. These mines in 2013
produced over 60 million tones of coal, or 70% 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

Currently degasification is performed at 37 mines that account for 41% of total coal production in Ukraine, including 20 mines not
owned by the state, with annual production of 28.6 million tones, and 17 state mines with annual production of 10 million tones.
On 10 mines degasification is applied periodically, depending on rate of coal mining.

Prospects of increase in objects of degasification and the subsequent
utilization of gas - methane on mines of Ukraine are possible at the
expense of increase in number of mines, sites where is degasification,
reconstruction of underground vent networks, by increase of efficiency
of degasification, application of degasification from a surface, utilization
of methane for the purpose of obtaining electric energy, heat, etc.
1. Introduction of the approved technologies of preliminary degasification
of coal fields, due to drilling of wells from a surface with hydraulic
fracturing application.
2. Conducting researches on preliminary degasification, taking into account
collection properties of the breeds containing coal layer. Permeability of
sandstones makes <0,1 mD (millidarcy), porosity of sandstones on
average 5 ÷ 6%.
3. Increase of production level in clearing faces >1000 t/days and rates of
advancing of a face for the purpose of growth of intensity of methane
release.
4. The application of advanced technologies and equipment for
underground degasification allowing drill vent wells extent more 100m
and with a diameter more than 100 mm.
5. Reconstruction of mine vent networks increase in diameter of the
pipeline with 250 ÷ 350 mm to 400 ÷ 600 mm.
6. Use of the equipment of degasification control with support of its
parameters first of all (concentration>25%) and productivities.
7. Improvement legislative and normative documents on stimulation of
investments and the preferential taxation.
Main directions of increase of degasification level
and methane utilization
Decrease in level of accident rate and increase of safety of miners
work;
Increase of use level of alternative types of fuel;
Creation of prerequisites for increase in volumes of coal mining;
The possibility of receiving by mines is cheaper than electric and
thermal energy;
Receiving additional financial resources by results of joint activity
of mines (enterprises) with the investor in the sphere of
degasification and utilization of mine methane;
Essential reduction of greenhouse gases emissions;
Creation of additional workplaces.
EXPECTED RESULTS
from implementation of methane degasification
and utilization projects in Ukraine:
Thank you for your attention!
