Power supply, control and automation systems of the high-performance plough
systems based on the example of LW Bogdanka S.A.
This paper presents the experience gained during development, implementation and commissioning of the high-per-
formance plough system of new generation at LW Bogdanka SA and describes in detail the power and control system
taking into account the automation process of plough systems. Therefore it becomes necessary to develop power
supply and control systems for the high performance plough systems, so as to offer on ongoing basis such electrical
equipment, which will completely fulfil the technical and economic tasks. It should be emphasized that the plough tech-
nique poses numerous new challenges to be met by each element of the system - only overcoming these challenges
guarantees full economic success for mining companies, that translates proportionally to the success of cooperating
with them companies. The challenges set by the new generation of ploughing technique should result in development
of other shearing machines, including shearer loaders not requiring direct handling. Certainly, particular importance will
be assigned to non-contact switches enabling flexible adjustment of drive motor revolutions in mining machinery.

Determination of cuttability of coal seams and the surrounding rocks in undergro-
und conditions by means of a device designed at GIG.
In this paper, a device for cuttability measurements of coal seams and the surrounding rocks in underground conditions,
designed at GIG has been presented. Part of he article is dedicated for the review of cuttability measurement methods of
rocks, applied in Poland and abroad so far. After that, the main elements of the device have been described as well as
a procedure for performing measurements in underground conditions presented. Simultaneously, the examples of the
underground measurement results have been given.

Mining of the hard coal seams in the mines belonging to the Katowicki Holding
Węglowy using shearer longwall system
The possibilities for mining of the coal seams in mines belonging to the Katowicki Holding Węglowy are presented in
this paper. Amount of coal which can be mined from coal seams was analyzed as well as its basic parameters i.e. he-
ating value, ash content and sulphur content. Moreover technical specification of the shearer longwall system for low
longwalls, manufactured by the Famur company, is presented. This system is used during mining of coal seams in KWK
“Murcki-Staszic” Ruch “Staszic”.
