The Oranje Nassau IV (located in Heerlerheide, Heerlen), the last and smallest mine exploited by the Oranje Nassau Mijnen, started its life as a ventilation shaft for Oranje Nassau III. In 1910 the construction of a mine shaft was started. However the construction was halted and only reassumed in 1919, the mine became operational in 1927.

Underground, the mine was connect to the Oranje Nassau III and, for safety reasons, also the Staatsmijn Hendrik. In 1966 it became the first of the Oranje Nassau mines to close; though mining activities continued until 1973via Oranje Nassau III.

The mine was 740 metres (2,430 ft) deep and produced 13,754,000,000 kilograms (3.0322×1010 lb) of coal during its operational period.

The terrain is now used by the Sigrano, a silversand mine, part of Sibelco [nl].
