Real time 2D blasthole burden measurements in the palm of your hand

BurdenAce old

BurdenAce® is a hand held laser instrument, which allows shot firers and drillers to safely and quickly measure the rock burdens in front of shot holes (at any point on the rock face) and display the result.

The palm-sized BurdenAce® incorporates a class 1 eye-safe pulsed laser and integral inclinometer. A red dot aiming scope allows the operator to aim and measure the range and inclination at passive targets up to 300m (1000ft). 2 x AA cells supply power and the whole unit weights just 1.5lbs (600g). The laser is equipped with an RS232 port for data output to printer, data logger or computer.

To measure a profile the operator simply fires the laser at the crest and toe of the face. The face length, angle, toe distance and bench height are immediately calculated and displayed. Enter the proposed drill angle, crest to collar offset distance and planned burden into the laser, after which individual points on the rock face in front of the hole can be measured.

For each point the actual burden, hole depth and percentage of burden are displayed and printed. Once the profile is finished the printed summary gives maximum and minimum burden values at their corresponding depths down the hole.

An optional hard copy printer is available which connects directly to the BurdenAce®. No additional computer or logging device is required!

The whole system can be easily upgraded to a 3D system by the addition of the MDL horizontal angle encoder and monopod or tripod. Software is available for 2D and 3D face profiling as well as stockpile volumetric measurements.

The BurdenAce® real-time handheld profiling system is based on MDL's LaserAce® 300 handheld laser range finder technology. The MDL BurdenAce® is a simple cost-effective tool for calculating rock burden profiles in front of shot holes.

BurdenAce and rockface BurdenAce and compaq
