Isaac Plains open-cut coal mine is located close to Carborough Downs in Central Queensland, Australia. It is 50/50 owned by Vale Australia and Aquila Resources Ltd. The mine is managed by Isaac Plains Coal Management on behalf of the joint venture parties.
The 60,000 square kilometers Bowen Basin contains the largest coal reserves in Australia. Isaac Plains mine coal is classified as medium volatile bituminous coal with low sulfur content.
Isaac Plains mine shipped its first coal in October 2006. Coal is processed at the Isaac Plains coal processing plant and then railed 172 km to the Dalrymple Bay Coal terminal for shipping to international customers.
In 2011, the mine produced 548 kt thermal & 1,270 kt metallurgical coal.
Isaac Plains coal mine is located 7 km southeast of Moranbah in Queensland, Australia. The project is situated between the Goonyella main railway line and the Peak Down Highway which service the northern area of the Bowen Basin.
Queensland is the second-largest and third-most populous state of Australia, located in the northeast of the country. To the east it is bordered by the Coral Sea and the Pacific Ocean. The capital and largest city in the state is Brisbane, Australia's third largest city. Moranbah is a coal mining town located 191 km west of Mackay.
The 60,000 square kilometers Bowen Basin contains the largest coal reserves in Australia. Coal was discovered in the basin in 1878 by Robert Logan Jack - a Queensland Government geologist.
Coal seams in the Bowen Basin exhibit major variations in rank and quality, reflecting both the depositional and tectonic history of the basin. Coal rank increases from west to east.
The Isaac Plains coal is classified as medium volatile bituminous coal with low sulfur content. It is classified as thermal and metallurgical coal. Coal seams amenable to open cut mining occur in two seam groups and up to six seam splits. The coal seams dip to the east, generally at less than 5 degrees.
As of December 2011, coal reserves stood at 18.6 million tonnes.
Issac Plains coal mine is a conventional open pit mining operation. The current mining lease covers 2,940 hectares.
The project consists of 5 planned open cut pits positioned along the north-south striking seam subcrop. The entire project infrastructure is located in the North West corner of the mining lease, including a 5 km rail loop, a 500 tph wash plant, train loading facilities, and water and
power reticulation facilities.
The mining strips are typically aligned north-south, perpendicular to the dip of the coal seams which is 5 degrees to the east.
Overburden is blasted and placed in previously mined void. Trucks and hydraulic shovels move all material - coal and overburden.
The mine is managed by Isaac Plains Coal Management on behalf of the joint venture parties. The coal is classified as a medium volatile bituminous coal with low ash and sulfur contents.
The project was established with an initial capacity of 1.6 Mtpa (75% metallurgical, 25% thermal) for export through the Dalrymple Bay Coal Terminal which is located 172 km away.
Coal is washed - impurities removed - before being stockpiled and ready for transport on the railway over 172 km to the Dalrymple Bay Coal terminal for shipping to international customers.
At the the Coal Handling & Preparation Plant coal is split into coking, PCI (Pulverised Coal Injection) and thermal coal fractions.
In 2011, Isaac Plains produced 548 kt thermal & 1,270 kt metallurgical coal.
Isaac Plains Coal Management is committed to minimizing the affect the project has on the environment.
The company has purchased and installed real time automated water monitoring stations on its major creeks; has invested in an automatic
weather station located near the Mine Infrastructure Area, and is currently looking at sourcing real time dust monitoring equipment for
installation at sites which maybe considered sensitive.
The company is committed to conducting progressive rehabilitation as soon as areas are available for topsoiling and seeding.
