The discovery of coal in the Ereğli (Heraclea) region (known today as the Zonguldak basin) dates back to the reign of Sultan Mahmud II, and its extraction to Sultan Abdülmecid's reign.

The first specimen of Turkish coal was brought from Ereğli to Istanbul in 1822, but nothing was done for exploration and exploitation of this coal.
However, in 1829, another specimen of coal was brought to Istanbul by Uzun (Long) Mehmet, a sailor and native of the village of Kestaneci, near Ereğli.
This time attention was given to the discovery and the sailor received a reward of a life pension, but before he could benefit from this reward he was murdered.

The first miners requested and delivered from the Austrian Government are the Austrian Croats known to have been employed in the Ereğli Coal Mines.
The correspondence between Istanbul and the embassy in Vienna show that coal production in the Ereğli Basin predates the March 1837 request by 18 months and that production started around September 1835.

An investigation of Hazine-i Hassa (Ottoman Imperial Treasury Department) records in the
Ottoman archives shows that regular mining activities in the Ereğli Basin started in February 1841.
This is confirmed by a newspaper article published in the 14 February 1841 issue of Ceride-i Havadis.

Ereğli Coal Company, chartered by six partners (Ahmed Fethi Pasha, Rıza Pasha, Safveti Pasha, Tahir Bey Efendi, Izzet Pasha and Mustafa Efendi), excavated the coal in the Ereğli Coal Basin, initially under the auspices of Darphane-i Amire and later transferred to Hazine-i Hassa when the latter was established in 1849.
