35 years since first longwall launched at Bogdanka

Thursday, 2017-11-30

30 November 2017 will see the 35th anniversary of launching the first mining longwall in the Bogdanka mine, which marked the beginning of industrial coal extraction in the Lublin Coal Basin.

The first longwall was launched about 8 years after KLZW was established and slightly over 2 years after horizontal mining had re-started following a mining incident caused by the influx of quicksand, which required removal of water from shafts.

The first (test) longwall was prepared in the direct vicinity of the shaft pillar in Bogdanka and was progressing westwards. Extraction was taking place “on the advance”, which minimized the amount of preparatory work required to launch the longwall. 

In April 1982, shaft S.1.2 in Bogdanka was connected with shaft S.1.4 in Nadrybie via a ventilation gallery in seam 382.

This marked the beginning of preparatory work aimed at launching the first longwall 1/I (referred to as the test longwall), which was commissioned on 30 November 1982. This 100-metre longwall has been mined from the bottom pillar of shafts S.1.2 and S.1.3 “on the advance” with cover caving westwards. The first longwall, launched 35 years ago and marking the beginning of industrial coal extraction in the new Lublin Coal Basin, was very modest in today’s terms: 100 m long and yielding less than 800 t per day, it was limited by the capacity of shaft S.1.2 used to carry the run-of-mine to the surface in carts.  Mechanization equipment of the longwall was selected specifically to suit the barely explored Coal Basin: a newly designed Fazos-17/37 Oz lining, Rybnik-73 conveyor, and KBW-3RDU/B (followed by KWB-3) coal-cutting machine. At the time, this was state-of-the-art machinery.

During the 35 years of mining activity in Bogdanka, approximately 147 million tonnes of hard coal have been extracted. In that period, 72 longwalls have been in operation to contribute to that output (including the current ones), with total length of more than 150 km. Seam 382 was extracted through 40 longwalls with total length of 80 km. Seam 385/2 has had 28 active longwalls with total length of over 66 km. At the moment, a third longwall is active in seam 391, and the first longwall in seam 389 has been launched in 2017.

Lubelski Węgiel BOGDANKA S.A. is the most modern and one of the largest hard coal mines in Poland.  In 2016, Bogdanka’s production of commercial coal amounted to more than 9 million tonnes.

Mine in Bogdanka conducts mining operations with respect to extraction, agglomeration and sale of hard coal. The BOGDANKA mine supplies mainly the industrial customers based in the eastern and north-eastern Poland. Market of customers is stable, and the sale is carried out mainly under long-term agreements. The main sectors where LW Bogdanka S.A. supplies its commercial coal include commercial and industrial power sectors.  

The Company’s financial results and hard coal extraction efficiency distinguish the Company from other organisations in the industry.
