ISSUE AND ITS CONNECTION WITH
SCIENTIFIC AND PRACTICAL TASKS
Nowadays, one of the main tasks of
Ukrainian coal industry is increasing labour
productivity by means of complex mechaniza-
tion and automatization of mining operations
with usage of modern equipment. The best
example is implementation of modern plow
complexes on Western Donbas mines, PJSC
“DTEK Pavlogradvugillia”.
Currently, plowing is one of perspective
directions of coal extraction development. Al-
ternatively, to shortwall stoping machines
with help of plow complexes we have oppor-
tunity to reach high-grade quality of extracted
coal and decrease ash content by means of
wall rock cutting reduction. As a result, we
can increase quality of finished products in
several times.
The main issue that retards widespread use
of plow techniques in Western Donbas is hard
mine-geological conditions (low thickness of
coal seams, low rocks hardness of main and
immediate roof, high inflow of water in mine
workings, etc.).
RESEARCH ANALYSIS OF GIVEN ISSUE
Experience of plow techniques usage on
coal mines has been considered on many data
sources.
Implementation of plow techniques on LW
Bogdanka mine is considered in article [1]. Au-
thor Zbigniew Stopa describes mine-geological
conditions of operations conducting and indus-
trial results that were received in stoping face
114
1/VI on seam 385/2. In work [2] author sub-
stantiates advantages and disadvantages of
plow complexes application during mining of
thin and very thin seams comparatively with
traditional methods of shearer mining. Also in
this work described experience and practical
results of plowing in stoping faces of JSW S.A.
mine, where a large part of stocks composes in
thin coal seams.
Operation of plow complex in hard mine-
geological conditions is considered in work
[3]. The author proposed different technologi-
cal schemes of coal seam mining in hard con-
ditions on the base of wide experience of
plow techniques implementation.
In work [4] covered the question about
plow complex application in conditions of
Western Donbas. A model of coal-bearing
massif and mechanized complex was built on
the base of computer and experimental re-
search.
In spite of the fact that considerable vol-
ume of research in given area had been real-
ized, the question about implementation of
plow complexes in Ukraine is still very actu-
ally. Equipment adaptation under local mine-
geological conditions is necessary for success-
ful application of plow techniques. Rational
parameters substantiation of operations that
will allow leading accident-free mining of ex-
traction mine working is also necessary.
PURPOSE AND OBJECTIVES
The main purpose of this article is analysis
of global and native experience of plowing ap-
plication in coal industry and perspectives of
plow complexes widespread use in hard mine-
geological conditions of Western Donbas.
To achieve given purpose authors estab-
lished following objectives:
1. To analyze experience in plow systems
application in Ukraine and abroad;
2. To consider factors that retard large-
scale implementation of plow systems on
Western Donbas mines.
STATEMENT OF MAIN MATERAL AND
SUBSTANTIATION OF OBTAINED RESEARCH
RESULTS
Plow systems are widely operated on
seams with low and medium thickness in
leading coal mining countries. Modern plow
complexes have high reliability and capacity
that provides good productivity during coal
extraction and absence of workers in working
area with help of automatization systems.
On German coal mines development of
seams with thickness from 0.6 to 2m is con-
ducted with help of modern plow systems.
Spectacular example can be stoping face op-
eration on “Prosper Haniel” mine, where av-
erage daily production was equal to more than
10,000 tons in August 2003 [5].
Experience in plow techniques application
on German mines shown supportability of
high rates on thin (to 1 m) seams. Example is
“Niderberg” mine, where in 1998 on seam
with thickness 0,75 m average load on long-
wall with length 318 m was equal to 3339
tons per day, on mine “Friedrich Heinrich” –
3270 tons per day at longwall length 280 m
and seam thickness 0,86 m. In 2006 on eight
German mines were 21 stoping faces in ex-
ploitation, average load on longwall was equal
to 4000 tons of marketable coal, near 50 mil-
lion tons of run-of-mine coal.
As for operating expenses during coal ex-
traction and prime cost of coal, maintenance
of shearer faces in Germany is almost on 9%
more expensive than plowing. Comparison of
the most productive longwalls show weightier
results: extraction in plow stope is almost on
20% cheaper than in shearer one.
Especially good results of plow techniques
application were achieved on “Bogdanka”
mine (Poland). During extraction of seam
with thickness 1,63 m managed to reach pro-
ductivity in 17000 tons per day.
On Russian mines, quantity of extracted
coal with help of plow systems grows up. For
example, on “Abashevska” mine, coal seam
with thickness 1,36 – 1,58 m and longwall
length 220 m was developed face with help of
“DBT GMbH” with plow “GH 9-38ve/5.7”.
115
Average daily production was equal to 4500
tons.
On Figure 1 shown comparison diagram of
stoping faces productivity that equipped by
plow systems.
Fig. 1. Productivity of leading coal mines
that equipped by plow systems
At present time in Ukrainian coal industry
quantity of stoping faces with plow systems
gradually increases, however most of long-
walls are still equipped by shearers (Table).
From 165 working faces 91 was equipped
with supports of new technical level, 59 – old-
fashioned and in 6 stoping faces used supports
of foreign manufacture, including 3 complexes
of Czech firm Ostroj and 2 of German DBT.
Most part of stoping faces (97 units)
worked on thin coal seams (less than 1,2 m) in
Ukraine and spectacular example is mining of
longwall 161st seam 6С “Stepova” mine “Per-
shotravneve” Mine Management PJSC “DTEK
Pavlogradvugillia” [6]. Production unit is situ-
ated on the depth 300 m and developing up-
dip on seam 6C (average angle of dip 4º) with
extracting seam thickness 0,9 m. In longwall
with length 300 m reached average load on
stoping face 3000 tons, but in some period, it
ranges to 5000 tons per day.
AVERAGE DAILY LOAD ON LONGWALL IN MINES THAT EQUIPPED WITH COAL-CUTTING
SHEARERS AND PLOWS WITH PRODUCTIVITY MORE THAN 2000 TONS PER DAY

In spite of definitely rhythmical work of
face complex, daily average rate of stoping
face changes in sufficiently wide range, in
particular due-to emergency shut downs dur-
ing of which was observed intensification of
rock pressure manifestations by way of roof
lowering, increasing of load on support and
wearing-out of pressure-release valves on hy-
draulic props of some support sections. Also,
observe perturbations of rock pressure mani-
festations intensity at different daily average
advance rates of stoping face. For instance,
during two months of this year happened
seven emergency shut downs of plow com-
plex with duration of more than 12 hours. The
reasons were different, including roof rocks
inrush. These shut downs concur in space
with sharp decreasing of immediate roof two
116
layers thicknesses to 0,4 – 0,6 m that repre-
sented by siltstones and mudstones with thin-
foliated structure and poor binding with ad-
joining lithological differences. Also poor
binding observes between layers of main roof
that also represented by siltstones and mud-
stones with total thickness 11 – 12,5 m, but
upper boundary of collapsible main roof is
seam 1
6C , where binding with underlying lay-
ing is completely absent. Computer monitor-
ing is realized by means of periodical data
sampling from operations system manage-
ment in longwall.
However, seams mining on “Stepova”
mine has own specific character that con-
nected with hard mine-geological conditions:
– rocks of roof and bottom are weaker
than seams (f = 1 – 4), slightly metamor-
phosed, foliated and fractured;
– high strength characteristics of coal
seams (f = 3 – 4 prof. Protodiakonov scale);
– certain lithological varieties (sandstones,
small coal seams and interlayers with high
water inflow that lead to siltstones and mud-
stones and decrease their durability;
– low cohesion between main and imme-
diate roof layers.
These specialties essentially decrease con-
ditions of mining operations conduction be-
cause of rock pressure manifestations inten-
sity, but thin and very thin coal seams do not
support to high-productive mining.
CONCLUSIONS AND PROSPECTS
OF FURTHER RESEARCH
1. Plow techniques are very perspective for
implementation on Ukrainian coal enterprises.
2. We can change shearers on seams with
thickness to 1,6 m and get a high production,
coal of the highest grade of quality and lower
ash content by means of full reject from wall
rocks cutting with help of plow systems.
3. It is necessary to take into account spe-
cifics of hard mine-geological conditions for
providing accident-free operation of extrac-
tion units. For Ukrainian coal industry and
especially Western Donbas during plow com-
plexes usage.
