·Coal mining is the process of extracting a coal reserve from the ground As a commodity coal is valued for its energy content and since the nineteenth century has been widely used to generate electricity and as a fuel source for the steel and cement industries Open cut hazards are principally mine wall failures and vehicle collisions
·Spontaneous combustion and low temperature oxidation of waste coal and other carbonaceous material at open cut coal mines are potentially significant sources of greenhouse gas emissions However the magnitude of these emissions is largely unknown In this study emissions from spontaneous combustion and low temperature oxidation were
·The process is repeated in successive parallel cuts until the stripping ratio indicates that continued surface mining is uneconomical Open pit mining In open pit mining of the coal seam several benches are established in both the overburden strata and the coal seam The open pit method is generally practiced where thick coal seams are
Coal mining by open cut methods A dragline is used to remove overburden from a gently dipping coal seam placing it in spoil piles on the up dip side left A pattern of blast holes has been drilled into the overburden on the right of the image The coal is removed by a power shovel and placed into trucks for haulage from the mine
·One of these processes is the open pit mining process Overview of Open Pit Mining Process Open pit mining which is also known as open cast or open cut mining is a type of surface mining process that extracts rock or minerals from the ground from an open air pit This type of mining process is mostly used in the mining industry around the

·the decision and what tools are used to assist in the process This paper looks at some of the issues driving the decision making and the tools used in the process may allow a decision to commence open cut mining to recover coal from subcrops pillars or to provide greater resource recovery
·In contrast open cut mining is generally safer as it involves working in open spaces with better visibility and ventilation Production rates In terms of production rates open cut mining is typically faster than underground mining This is because open cut mining can use larger equipment and can extract the resource more quickly from the
We produce high quality coal using open cut mining methods in NSW and QLD as well as underground mining methods at Narrabri in NSW Washing plants and processing facilities improve the quality of coal and enable the production of higher value coal Washing reduces ash increases energy content and improves the market value Coal is also
·The article describes a problem of considering the coal strata bedding for the scheming of dragline mining technology for open pits developing flat seams For three flat coal seams strata processing the main criterion defining the choice of technology of their processing is the stratigraphic positioning rate for the middle coal seam It is the ratio of the upper and lower
