Mine Life2037
The existing Ensham Mine operation is an open-cut and underground bord and pillar coal mine. The proponent extension project is proposing to extend the life of the existing Ensham Mine nderground operations by up to nine years beyond the existing Ensham Mine, with sufficient coal reserves to approximately 2037.

Summary:

The Ensham coal mine (Ensham) is located approximately 40 km east of Emerald, Queensland.

Within the Ensham area, the Rangal Coal Measures comprise the Aries, Castor, Pollux and Orion seams in descending order, the upper three being exploited by open cut mining and the Aries Castor being exploited by underground mining methods. Seam thickness in the open cut area averages 5 to 6 m whilst the underground area generally comprises a single seam averaging 3 m in thickness.

Ensham produces only a limited amount of semi soft coking coal, with the majority product being a low ash, sulphur, high energy thermal coal. They can produce thermal coals with ash content between 10 to 16% and a calorific value of 6000 to 7000 kcal/kg. Total sulphur content commonly ranges between 0.6 and 0.9% and volatile matter is commonly in the order of 25 to 27%.

Summary:

The existing mining operations at Ensham Mine consist of open-cut and underground operations. The opencut operation is scheduled to continue to approximately 2024, followed by further rehabilitation of the open-cut mine. Existing underground operations are due to cease in 2028.

Underground mining.
The underground operations currently use the bord and pillar mining method. This involves the use of a continuous miner to remove the ROM coal while leaving a series of coal pillars to support the roof.

The existing underground workings are accessed through portals located in Pit C. The portals are used for conveying ROM coal from the workings to the Coal Handling Plant (CHP) and for personnel and materials access.

Extracted coal is transported by a system of underground conveyors to the surface. Coal is then transported by semitrailers to the CHP where it is crushed and sized. Product coal is transported via rail to Gladstone for the Gladstone Power Station and to the port for export.

The underground mine services are largely integrated wherever possible with those of the open-cut mine in aspects such as coal handling, transport, waste and water management.

Open pit mining.
The Open Cut is a dragline operation with one active dragline removing overburden. Once exposed, the coal is removed by excavators and trucks and placed on stockpiles.
