Vertical sequencing constraints require that if machine placement a lies directly above machine placement b, then the earliest time at which machine placement b can start to be mined is the time at which 50% of machine placement a has been mined (subject to LHD availability). This prevents the overlying sublevel from caving onto the underlying sublevel.
