MR620 Roadheader offers opportunity for improvement of drift driving efficiency
This paper presents a roadheader of 600 series suitable for mining of rocks of UCS of up-to 140 MPa. In addition, optio-
nal equipment for the roadheader, in particular bolting equipment, is discussed. Impact of changes in technology of
gangway driving on daily advance rate is discussed on the basis of simulations.

„Lubin” mine experiences in driving heading excavations with Sandvik Mining and Con-
struction’s MH-620 heading machine
The experiences gained during the drive of heading excavations with Sandvik’s MH-620 in two entirely different areas
of “Lubin” mine are shown in the article. The influence of imperfect construction of the machine on the heading drive
process has also been highlighted.

Construction and Maintenance of Longwall Galleries for Plough Longwalls in the
Mine of Lubelski Węgiel Bogdanka S.A.
The article discusses the determinants associated with the selection of the support system for longwall galleries for
longwalls mined with the plough technique. It contains an overview of the different alternative solutions analysed and
the solution employed in the mine of Lubelski Węgiel Bogdanka S.A. in the case of the first plough longwall 1/VI/385,
located in seam 385/2 in Nadrybie field. It presents further works undertaken to improve the support system frames for
the second longwall equipped with the first plough system (longwall 7/VII/385) located in the same seam in Stefanów,
but smaller in thickness (1.2-1.5 m).
