Why was Murton Colliery closed?

Murton Colliery was closed primarily due to economic factors, including declining coal demand and increasing operational costs. The shift towards more efficient energy sources and the depletion of accessible coal reserves also contributed to its closure. Additionally, government policies and changes in the coal industry further impacted its viability. The colliery ceased operations in the early 1990s, reflecting broader trends in the UK coal industry during that period.
