Abstract
A system for blast hole data collection for use in a mine site incorporates an instrument configured to acquire geological property data of a blast hole for processing in the system or remotely and a vehicle having a handling system configured to move the instrument into and out of the blast hole as an interchangeable element with a drill string or prior to explosives charging and charging the blast hole in accordance with a determined charge profile.
Claims18
A method of explosive material charging comprising:
- aligning a geological measurement instrument, supported on a vehicle, with a bore hole;
- operating the instrument while lowering the instrument into the bore hole and/or while retrieving the instrument from the bore hole to acquire geological data of the ground in which the bore hole exists at a plurality of depths in the bore hole;
- streaming the geological data with a data transmission system in the instrument in real time to a data receiver;
- using the geological data, acquired by the instrument at the plurality of depths in the bore hole, to determine geological characteristics of the ground surrounding the bore hole and determining a charge profile by selecting two or more different explosives for the bore hole as a blast hole using the geological characteristics, while withdrawing the instrument from the bore hole and parking the instrument on the vehicle;
- and
- autonomously charging the blast hole by the vehicle by depositing the two or more explosive materials in accordance with the charge profile determined on the basis of the geological characteristics of the ground surrounding the bore hole, with the charging depth of the each of the two or more explosives dependent on the geological characteristics.

A method of explosive material charging of a blast hole comprising:
- streaming geological data with a data transmission system in an instrument inserted into a bore hole to a data receiver;
- operating a second geological measurement instrument when charging the blast hole and comparing the measurements of the instrument and the second instrument,
- using the geological data, acquired by the instrument at a plurality of depths in the bore hole, to determine geological characteristics of the ground surrounding the bore hole and determining a charge profile of explosive materials for the bore hole as the blast hole using the geological characteristics;
- and
- autonomously charging the blast hole by depositing one or more explosive materials with a vehicle on the basis of the determined charge profile for the geological characteristics of the ground surrounding the bore hole.
