Open Cut allows you to:• Mensimulasikan suatu desain tambang untuk tahapan short-term
production operations & long-term feasibility studies• Menggunakan Minescape CAD tools untuk visualise dan
• Graphically.Dengan sistem perhitungan reserve yang dapat memastikan Vol ton dan Grades, sehingga setiap komponen dapat dihitung secara akurat dengan menggunakan software selain minescape.
OPENCUT PROCESS PREVIEW
OPEN CUT PROCESS
OPENCUT PROCESS
STARTING OPEN CUT PROJECT
1. Open Design file Block2. Create New layer (ex: Polygon)3. Copy duplicate polygon sheet/boundary area project to layer polygon
there are 2 ways to make boundary polygon; first using poly sheet togenerate batter block over all of the area project; and the second using
contour oratio and this way means only this area will be generate block4. Copy duplicate subcrop of lower seam that to be mined5. Create 2 line parallel with subcrop line which cover project area ( this line
will be used as reference to the generate strip)6. Create 2 line which across the first line ( this line will be used as
reference to generate block)7. Create Side definition for High wall, side wall and low wall using :
Minescape explorer Spec Create Spec category : Side8. Tag each side of the polygon boundary using menu Strip_Design Tag
Design Segments (for example : high wall using hw55, side wall usingsw55 and low wall using lw30).

Tips :Solids dapat diproyeksikan, hanya pada area yang tercover oleh surface topo (pada area crest),Dan surface floor(pada Toe area).Sehingga baiknya disimulasikan dahulu untuk total areanya

Result of generate Pit design will create new layer name asaccording to name which filled at form, for example :crest_line; toe_line; Ramp line; and Rays_line. Copy duplicateobject from those layer into one layer for example pit_1

Create Pit Floor
1. Create new layer at design file Pit Design ( for ex : pit_floor)2. Attach contour structure floor of lowest seam, and copyduplicate to layer pit_floor3. Displaying polygon_pit and relimit that contour structureusing this polygon
