Understanding and Controlling Coal Damage During
The open cut coal mining industry in Australia recognised that cast blasting increases coal damage and loss associated with overburden blasting but very few mines have quantified its impact on overall mine economics An ACARP project "Understanding and Controlling Coal Damage in Cast Blasting" was undertaken by the Julius Kruttschnitt Mineral Several open pit coal mines in Australia recognise that overburden blasting especially cast blasting, increases the likelihood of coal damage and loss resulting in significant negative economic impact on their operations and identified that block movement of coal during overburden cast blasting to be an issue at several mine sites for Controlling Block Movement of Coal During Batchfire’s Callide Coal Mine in Central Queensland is an opencut operation located 120km southwest of Gladstone and 20km northeast of the township of Biloela The mine produces approximately 12 million tonnes per year of low sulphur, subbituminous thermal coal for both domestic power generation and exportCase Studies Conference Papers Orica Mining The open pit or open cast mining method is the obvious choice for a property with a wide area of mineralization exposed or existing close to the surface and continuing to greater depths The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocksOpencast Mining an overview ScienceDirect Topics China has the largest coal production in the world due to abundant resource requirements for economic development In recent years, the proportion of opencast coal mine production has increased significantly in China Opencast coal mining can lead to a large number of environmental problems, including air pollution, water pollution, and solid waste occupationLife cycle assessment of opencast coal mine
