Sasol Mining operations
Sasol Mining’s underground mining operations include Impumelelo, Bosjesspruit, Shondoni, Syferfontein,Thubelisha (all in the Secunda area) as well as Mooikraal (near Sasolburg).  Sasol Mining’s ambitious R15 billion built programme, has replaced 60% of its operations and this will ensure uninterrupted coal supply to Sasol Synfuels Operations. These mine replacement projects support Sasol's strategy to operate its Southern African facilities until 2050. 

The following mines supply feedstock to Secunda Synfuels Operations:

The first of these new replacement mines was the R3,4 billion Thubelisha mine commissioned in May 2012. Thubelisha replaced Twistdraai Colliery.  It is envisaged that this shaft will eventually deliver more than 8 million tons of coal per annum (Mtpa) over 25 years.  

Impumelelo mine replaced the Brandspruit mine. Impumelelo is Sasol Mining's deepest mine at 198 metres.. It is also the farthest of all Sasol’s operations.  It is  50km outside of Secunda and has a 27km single flight conveyor to Sasol Coal Supply. Impumelelo has the capacity to produce 10,5 Mtpa, all of which will be dedicated to the Sasol Secunda Synfuels Operations. 

The Syferfontein Tweedraai project was completed in 2015. This included the shaft access developed with a CM instead of the planned blasting operation, and was successfully completed ahead of schedule and within budget. The Tweedraai shaft was designed to deliver 6 Mtpa over a period of 30 years.  

Shondoni colliery was commissioned in 2017 and replaced the Middelbult mine. It represents a R5,4 billion investment with a 9,2 Mtpa capacity and 30-year life of mine.

Bosjesspruit colliery was opened in 1977 and has produced more than 250 million tons of coal in the last 40 years. Current coal production takes place at Irenedale with a 17.9km underground conveyor running past the South shaft to the Bosjesspruit Main shaft. Bosjesspruit mines between six and 6.5 million Mtpa and and has a life of mine to 2031.
Sasol Mining produces about 40Mt of saleable coal per annum, which is mainly used as gasification feedstock for Sasol Synfuels in Secunda and utilities coal for the Sasolburg Operations.

At Sasol Mining, we aren’t just mining coal, we are unearthing opportunities.
