Katowice Coal Holding JSC (Katowicki Holding Węglowy SA) comprises four modern coal mines Murcki-Staszic, Mysłowice-Wesoła, Wieczorek andWujek. KHW SA is one of the biggest Polish and European Producers of high quality typical steam coal.
Katowicki Holding Węglowy S.A. was established on 29 June 1993 as a result of a merger of eleven mines – joint stock companies owned by the State Treasury. The established Company included the following mines: KWK Katowice S.A., KWK Kleofas S.A., KWK Murcki S.A., KWK Mysłowice S.A., KWK Śląsk S.A., KWK Niwka-Modrzejów S.A., KWK Wesoła S.A., KWK Wieczorek S.A., KWK Wujek S.A., KWK Staszic S.A. and KWK Kazimierz-Juliusz S.A. At the moment of entering KHW S.A. in the commercial register, the mines lost their legal personality and became plants owned by the Company.
The State Treasury is the founder and the sole shareholder of the Company. The Company's registered office is in Katowice. In 1996, the Katowice and Kleofas mines were merged, adopting the name Katowice-Kleofas. In the same year, KWK Niwka-Modrzejów and KWK Kazimierz-Juliusz were transformed into limited liability companies. In 1999, KWK Katowice-Kleofas - Ruch II (the former Katowice mine) and KWK Niwka-Modrzejów Sp. z o.o. went into liquidation. On 29.09.2000, the latter was declared insolvent. In November 2004, extraction at KWK Katowice-Kleofas was discontinued. The mine was transferred to Spółka Restrukturyzacji Kopalń S.A. (Mines Restructuring Company) in order to have the mining plant liquidated. On 23.01.2009, as a result of the completion of the insolvency proceedings, KWK Niwka-Modrzejów Sp. z o.o. was removed from the commercial register. On 1 January 2005, the Śląsk and Wujek mines were merged into one mining plant – KWK Wujek. On 1 January 2006, KWK Katowice-Kleofas was removed from the structure of KHW S.A. The remaining, undeveloped part of the assets of that mine was transferred to KWK Staszic. On 1 January 2007, Mysłowice and Wesoła mines were merged into an extraction centre – Mysłowice-Wesoła. On 1 January 2010, Murcki and Staszic mines were merged into a single mining plant – KWK Murcki-Staszic. On 30 June 2011, extraction was discontinued in the Mysłowice part of KWK Mysłowice-Wesoła.
As a result of those transformations, the number of mines included in KHW S.A. was reduced to four, namely KWK Murcki-Staszic, KWK Mysłowice-Wesoła, KWK Wieczorek and KWK Wujek. A fifth and smallest mine in the Group, KWK Kazimierz-Juliusz, operated as a subsidiary – a limited liability company. 6-th November 2014 it has been sold to Mines Restructuring Company which is going to finish operation and to execute shutdown of the mine
