Provided is a blast hole measurement and logging apparatus (10) which generally comprises a housing (12) configured to operatively house a solid-state LiDAR sensor array (14) configured to transmit and steer pulses of light (18) into a blast hole (8) by shifting a phase of said pulses through the array to compile volumetric data of said sensor's field-of-view. Also included is a processor (22) configured to receive the volumetric data from the LiDAR sensor (14), said volumetric data indicative of an internal volume of the blast hole (8) which is useable in calculating an explosive charge according to a blast plan, the processor (22) configured to store and/or transmit the volumetric data.
