H = Current height of gradeline above mine floor

dH = New height difference input for new gradeline

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
