to increase coal production and exploitation capabilities,
which is possible because of Stefanow field development.
Exploitation works are presently conducted simultane-
ously in seams 382 and 385/2 in Bogdanka and Nadrybie
fields. In Bogdanka area seam 382 is accessed from level
922 m and seam 385/2 from level 960 m. Seam 382 is
mined in the Northern part of the mining area and seam
385/2 in the central part between the protection pillar of the
shafts (field V) and in South-Western part (field IV).
Exploitation is conducted using the “advance” system,
with roof caving and simultaneous liquidation of longwall
headings with the advance of the longwall face. The length
of the longwalls is from 250 to 300 m and panel lengths
range from 2000 to 3000 m. The longwalls are equipped
in highly-efficient, mechanized longwall complexes, de-
signed for the parameters of the mined seams and for the
local mining and geological conditions. The mine owns 3
longwall complexes, suitable for mining seams of variable
thickness.
The daily production of the mine reaches 25000 tonnes
(ca. 17000 of marketable coal) from two longwalls oper-
ating simultaneously and from preparatory headings (10-
15%). Exploitation using long longwalls allows to achieve
high concentration of production and high work efficiency.
The production of “Bogdanka” mine is limited only with
the hoisting capacity of the skip shaft and the efficiency of
coal processing plant.
In 2007 the production of marketable coal reached 5,1
million tonnes (7,4 million tonnes of raw coal). During its
whole existence since 1982, “Bogdanka” mined over 75
million tonnes of coal.
“Bogdanka” is one of the most effective steam coal
mines in Poland and in Cental Europe. The effectiveness
of coal production is much higher than the industry av-
erage in Poland. The mining efficiency in three quarters
of 2010 was 291% of the average achieved in other Pol-
ish mines. The noted values of net pure coal production
reached 81% in 3rd quarter of 2010 in comparison to ca.
70% in the previous year.
Very good results achieved in technical and financial
areas are a derivative of achieved general and mining ef-
ficiency which are two times higher than the averages of
the industry. The present competitive advantage of the
company comes from the high effectiveness of resources
management is reinforced with advantageous location
of the mine near the biggest clients and consumers (this
constitutes for lower transportation costs than competing
companies may offer).
