What Is A Box Cut In Mining Box Cut Box cut mining is a cutting technique In general this cut is downcast adequately until rock not worn by exposure to the weather is found in order to permit the progress of the decline This type of cut is created to provide a secure and safe portal as way in to a decline to an underground mine In most mining areas it is box cut
In mining terms a boxcut also written box cut box cut is the first shallow excavation which serves several purposes in both open cut and underground mining operations coal and hardrock alike Contents Boxcuts for Open Cut Mine Development Boxcuts are optimally located along the limit of oxidation LOX line where fresh unoxidised Area strip mining In coal mining Area strip mining with a trench or box cut made through the overburden to expose a portion of the coal seam This trench is extended to the limits of the property in the strike direction After coal removal a second cut is made parallel to the first one and the overburden material Read More

BOX CUTIt is the opening cut or first cut given for the development of first working bench A blasting pattern for a box cut is shown here Figure 6 4 9 Blasting pattern for a box cut Sinking blasts like this vary from most blasts because there is no open face for relief and movement must be vertical Since entire blast is in the tight the vibration and fly rock damage potential is high These patterns can and will be modified ad
And number 4 the Box Cut There is a fourth means of access that is used infrequently but is common enough to warrant its own category It is known as a box cut You may recall learning this term earlier as this term is taken from surface mining and specifically the open cast mining method known as area mining The overburden from the box cut will be placed to the side of the pit When the coal seam under the box cut is exposed we start mining the coal After the coal in the box cut is removed a subsequent cut is accomplished and the waste material from the second cut is placed in the space created by the initial box cut

In cut and fill method of stoping the box cut excavation is done by driving sill drivages These sill drivages are further extended in the operation of stoping In longhole stoping method the box cut excavation is done by driving raises These raises work as the free face for the accumulation of rock in the subsequent excavation stages The underground mining methods we use include room and pillar narrow vein stoping and large scale mechanised mining Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds We use this for mining coal
ABSTRACT This paper describes the standard techniques used for a box cut excavation and mine opening applicable in mines that use the bucketwheel excavator stacker across pit mining systems XPS systems The typical application of these techniques is discussed along with the factors that will influence the selection of the most efficient Box cut development at the Kangala mine began in July 2013 A 54 hole infill drilling programme was conducted before starting the mining activities Coal is processed at Kangala in two stages namely 320 tonnes per hour tph dense media washing DMS plant and BC1 BC2 crushing and screening The coal allocated to ESKOM is processed using the
