Figure 1: Highwall mining systems (a) CHM system (after Caterpillar Inc.), (b) Auger mining system (Coal Augering Services 2014) Highwall mining has several advantages compared to underground operations and conventional surface operations. Firstly, due to its flexibility and mobility, it is easier to recover smaller blocks of coal, whichCoal Augering Services - Mining Technology | Mining,Auger mining operations drill a series of parallel holes perpendicular to the highwall, leaving adequately sized pillars between holes to maintain the stability of the highwall and overlying surface area. The technique is also commonly used to recover coal beneath surface features which limit surface mining, such as rivers and roads.Application of highwall mining system in weak geological,,Highwall mining systems have improved mining oper-ations due to their safety and productivity.
