Blast Movement Technologies' system employs ball-shaped directional transmitters
(BMMs) that are activated (top) before being placed in specified drill holes prior to
blasting. After the blast, a worker walks the muckpile, carrying a handheld detector
(right) that allows location of each transmitter. The collected BMM data is processed to
calculate overall blast movement and allow more accurate definition of ore boundaries.
the measured movement, thus enabling more precise selection of
ore and waste after the blast. According to the company, the data is
summarized and archived for later reference and over time the blast
movement database becomes a valuable resource of information
that can be used by blasters for optimization purposes.
Beyond the obvious use as an ore dilution prevention tool, BMT
says the BMMs can be used for additional purposes in D&B; operations, such as finding the location of the toe of angled blastholes without need of other tracking equipment, finding and recovering stuck
and abandoned bits after a blast, and identifying misfires in a pattern.

Blast Movement Technologies recently announced it will release a new version of its BMM software that will include many
new features, such as ore block import and export capabilities for
most popular mine planning software packages such as
MineSight, Surpac and Vulcan; and 3-D visualization of blasts and
BMM movement vectors.
