The BMM System, developed and marketing by Blast Movement Technologies in Australia, is the first time there has been a practical method which provides accurate 3-dimesional blast movement data. Despite the innovative technology, it is remarkably simple to use - designed for routine use by site personnel. This technology enables a genuine step-change in grade control and is generating significant interest from some of the world's largest mining companies. The BMM system enables production controls that were not possible previously and has shed new light on our understanding of blast dynamics which in turn leads to better blast designs.

A series of directional transmitters (BMMs) are activated, programmed and installed in dedicated drill holes prior to blasting. A special detector is used to locate the BMMs after the blast and calculate their depth. Data is downloaded to accompanying software that calculates the movement vector of each BMM. This data is then summarized and archived for later reference. With this new information, ore boundaries can be quickly redefined to reflect the measured movement, thus enabling more precise selection of ore and waste after the blast.
