Abstract
A blast hole measurement and logging apparatus, which generally comprises a housing configured to operatively house a solid-state LiDAR sensor array configured to transmit and steer pulses of light into a blast hole by shifting a phase of the pulses through the array to compile volumetric data of the sensor's field-of-view. Also included is a processor configured to receive the volumetric data from the LiDAR sensor, the volumetric data indicative of an internal volume of the blast hole which is useable in calculating an explosive charge according to a blast plan, the processor configured to store and/or transmit the volumetric data.
Claims20
A blast hole measurement and logging apparatus comprising:
- a housing configured to operatively house:
- a solid-state light detection and ranging (“LiDAR”) sensor array configured to transmit and steer pulses of light into a blast hole by shifting a phase of the pulses through the array to compile volumetric data of the sensor's field-of-view;
- and
- a processor configured to receive the volumetric data from the LiDAR sensor array, the volumetric data indicative of an internal volume of the blast hole useable in calculating an explosive charge according to a blast plan, and to extract intensity return data from the volumetric data, the intensity return data indicative of a surface reflectance of the blast hole which facilitates the processor in detection of water within said blast hole, the processor further configured to store and/or transmit the volumetric data.
The apparatus of claim 14, further comprising a display whereby the one or more of the volumetric data, the collated distance data, and the geographic positional data are displayable to a user.
