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
