Vari-Stem offers increased fragmentation, fracturing and cap rock breakage; and reductions in fly rock
, air blast, stemming ejection, dust, noise and oversized rock.

A fly rock is absolutely not allowed under the regulations and should not be happening.
Chief Ricard said a staff member assigned to monitor the blasting reported the fly rock.
Murray and Howlett (1994) observed that hydraulic drop ball rock breakage technique produces cleaner rock fragmentation, very low levels of ground vibration, minimal fly rock and dust and negligible toxic fumes.
In hydraulic drop ball technique, no significant fly rock was observed since the rocks were fractured and then fall-apart under the influence of blow energy from the machine.
The blasting shakes our houses like one earthquake after another, cracks walls and foundations and sometimes fly rock
falls down on us like it's raining rocks.
The most serious violations are complaints of fly rock
on adjacent properties.

The energy confinement provided by stemming plugs allows quarry and mine operations to realize improved blasting safety by reducing the occurrences of fly rock incidents.
Even a couple milliseconds of additional confinement can make a significant difference in enhancing blast performance and, therefore, curtailing fly rock," said McClure.
