Benefits of technology

This approach allows for efficient and cost-effective acquisition of geological data without additional vehicles or personnel, enabling precise charge profile design for blast holes, optimizing blasting outcomes and downstream processing, while minimizing disruptions to the drilling and blasting process.

Problems solved by technology

However these data typically do not provide a sufficient level of diagnostic information alone to fully determine the geological nature of the drilled material.
Further the sampling and processing performed by the machine substantially slows down the drill and blast method.

Embodiment Construction

Background Technology

[0025]FIG. 1 is an illustration of one type of drill rig 10 used for drilling blast holes. The drill rig 10 has a track mounted body 12 which includes an operator cab and a drill tower 14. The drill tower can be tilted through 90° between a horizontal position and a vertical position as shown in FIG. 1. A rotation head 16 is mounted on the tower for providing torque to a drill string 18. One or more hydraulic rams (not shown) are provided on the tower 14 for providing pull down or pull back to the drill string 18 via the rotation head 16. However as will become apparent from the following description embodiments of the disclosed method and system can be used in relation to other forms of blast hole drill rigs.

[0026]It is common for a drill rig 10 to be provided with a GPS to enable accurate positioning for drilling blast holes on a bench or survey data in underground applications. Indeed autonomous drill rigs are currently available which can be programmed with ...

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.
