Grades

Mining_z04

Introduction

"Grades" application is used to
mark gradelines along the side
walls of the mines (tunnels). It
allows users to input the slope
gradient and an offset
concerning the grade point. It
computes the stake out height
difference. The program allows
also to map the positions of the
grades points along the
gradelines.

Known:
• Coordinates and grade

elevation of station

• Coordinates and grade

elevation of backsight point

• Slope gradient (station until

foresight point)

• Height difference (dH)

between current gradeline
and new gradeline

Unknown:
• Stake out height difference

(dHgt) between measure
point and gradeline point

• Horizontal distance (dHD)

along the foresight line

Backsight Point

Station

Foresight Point

New Gradeline

H = Current height of

gradeline above mine floor

dH = New height difference
