Main Content

Clarence operates an underground coal mine; a coal handling and preparation plant (CHPP) and water treatment plant in the Western Coalfields of NSW near Lithgow.

2011 was a record year, with production exceeding 2 million tonnes of ROM coal for the first time using the partial extraction method of mining.

Clarence is at the forefront of Australian mining innovation, utilising Australia’s first JOY 4th Generation Flexible Conveyor Train (FCT) high capacity continuous coal haulage mining system. The FCT is a 110 metre tracked conveyor system that bends around corners while conveying coal to an underground, stationary coal receival hopper before being transported to the surface. An operator steers the FCT up or down the panel roadways with a radio remote control. As the FCT does away with conventional shuttlecars, it enables a significant increase in cutting time as the continuous miner unit no longer has to wait for returning shuttlecars.

Environmental Management is at the core of Clarence’s Operations. The mine’s Environmental Management System (EMS) ensures performance against all approvals and licence conditions and facilitates continual improvement.

Community Consultative Committee (CCC) meetings at Clarence are held quarterly to provide a forum for open discussions between representatives of Clarence, the community and other stakeholder’s on issues directly relating to the mine’s operation and environmental performance. In 2011 Clarence participated in a number of community activities including the Save Our Swamps Program and in 2012 has seen contributions to the Clarence-Dargan Rural Fire Service.

Environment Management Plans

Approvals obtained to facilitate mining generally require management plans in consideration of various identified environmental impacts. These plans vary from operation to operation to reflect the operating conditions.

Environmental Management Plans are required under Clarence’s various approval and licence conditions and form part of Clarence’s Environmental Management System (EMS). Management plans are developed and approved in consultation with the relevant government stakeholders.

Subsidence Management Plans

Subsidence Management Plans (SMPs) are prepared by mining lease holders to consider the potential impacts of underground mining and identify measures to manage such impacts. SMPs may contain requirements for the avoidance of damage to particularly significant features, the mitigation of damage, or rehabilitation of subsidence related impacts.

End of Year Subsidence Reports

This is an annual report that includes a summary of subsidence and environmental monitoring results for the year, an analysis of monitoring results against impact assessment criteria and SMP predictions, identifies trends in monitoring results over the life of the activity and describes what actions were taken to ensure adequate management of any potential subsidence impacts.

Environmental Management Reports

An Environmental Management Report is an annual report that consolidates all government reporting requirements relating to the environmental management and rehabilitation of the mine. It contains details on approvals, leases and licences, environmental control strategies, the previous 12 months’ mining and environmental performance and the expected outcome for the following 12 months.

Independent Environment Audit

Independent Environmental Audits are undertaken regularly as a component of each mining approval. The audit is undertaken by a suitably qualified independent expert. The purpose of the audit is to independently assess the environmental performance of the mine and whether it is complying with the relevant requirements of its project approval, any relevant mining lease and environmental protection licence.

A condition of Clarence’s Development Consent Approval requires the mine to commission an independent environmental audit prior to 31 December 2010 and every three years thereafter. Accordingly, the audit was commissioned in December 2010 and completed in February 2011.
