Management of Excess Mined-Out Space of Quarry Fields of Coal Open Pit Mines
2021
Regardless of the applied technology of coal mining, a technogenic resource of the open pit is formed – excess mined-out space. Excessive mined-out space should be understood as a part of the internal space of a pit that is not used for placing overburden in dumps. The excess mined-out space in the plan is limited by the following: on the flanks of the quarry field and along the uprising by the limiting contour of the quarry, along the inclination – by the possible position of the slope of the dump layer, as close as possible to the working area. The lower boundary corresponds to the position of the formed dumps, the upper one – to the marks of the dominant relief. The article presents a method for reducing the excess mined-out space by means of the patterns of spatial development of objects “quarry field – dump of overburden”.
