Summary:
Mt Owen is situated between two regional thrust faults, the Hunter Thrust and the Hebden Thrust that limit the lateral extent of the coal seams. Seam dips vary throughout the deposit, with dips being steep (up to 45 º ) in the areas near the Hunter and Hebden Thrusts where parallel thrusts dislocate the seam by up to 40 metres.
Up to 22 mineable coal intervals are recognised, ranging in thickness from 0.2 metre to 10 metres, within a stratigraphic interval of approximately 350 metres, the coal seams comprise a total thickness of approximately 55 metres.
The seams for which there is potential for economic extraction at Mt Owen include the Lemington Seams, Pikes Gully Seams, Arties Seams, Upper Liddell Seams, Middle Liddell Seams, Lower Liddell Seams, Barrett Seams, Upper Hebden Seams and the Lower Hebden Seams.
Summary:
Mining is carried out by large excavators and haul trucks supported by ancillary equipment including water carts, dozers, graders, fuel and service carts, loaders and drills.
The sequence of mining involves clearing of vegetation and topsoil, drilling and blasting of overburden, followed by the excavation and haulage of overburden from a series of sequential mining blocks to the emplacement areas. The coal that is uncovered is then hauled to the Coal Handling and Preparation Plant (CHPP) for processing. The clean coal is conveyed to the product stockpile before being transported by rail for approximately 120 kilometres to the port of Newcastle for export.
Mining at Mt Owen occurs within the Wittingham Coal Measures with the North Pit located between the Hunter Thrust and the Hebden Thrust. The North Pit currently extracts coal from 22 mineable intervals, representative of 11 identifiable coal seams. Coal seams present range from the Lemington to the Lower Hebden seam and range in thickness from approximately 0.1 m to 10 m.
In August 2017, MGO modified SSD-5850 (‘Mod 1’) to allow for the construction of a mine water pipeline from Integra Underground Mine to MGO. In September 2019, Modification 2 (Mod 2) to SSD5850 was approved. This allows the additional mining of 35 Mt of ROM coal and extends the life of mine to 31 December 2037. During January 2020, Modification 3 (Mod 3), an administrative mod, was approved by DPIE for the inclusion of on ........
