RIOTRONIC X+

User Manual

Subgrade = 8-12 blast-hole diameters for surface blasting operations. (Remember that rules

of thumb are just that, an initial first pass estimate).

In strong, massive rocks, subdrilling of about 8D is usually found to be satisfactory. But

subdrilling as high as 12D may be necessary in front row blast-holes in places where vertical

blast-holes shoot to relatively high or shallow dipping faces.

A Subdrilling below 8D can usually be employed satisfactorily in places where:



the rock is weak or contains well developed sub-horizontal fissures



blast-holes are inclined significantly to the vertical



a high energy per meter of blast-hole can be generated

Even when there is no change to blast hole diameter, subdrilling may have to be increased

with any increase in burden distance or blast-hole spacing.

Standoff is generally designed in the range of 4 to 8 diameters as the damage below the toe

of a blast hole is limited.

Main Points - subdrilling



subdrilling is required to keep good floor grade control



The general rule of thumb for subdrilling is between 8 and 12 blast-hole diameters



Excessive subdrilling will precondition the next bench and cause high vibration.
Insufficient subdrilling will cause toe and floor grade degradation.

9.3.6.

Explosives Distribution

The distribution of explosives along a blast-hole should be consistent with:



the bench height



the physical properties of the rock mass



the amount of fragmentation, displacement and muck pile looseness desired



the need, if any, to control noise, air blast and overbreak.

Single and continuous charges should be used in most blast-holes. As blast-hole length

increases towards a certain critical value, so should charge length and charge weight. Blast-

holes having a length exceeding this critical value should contain two deck charges rather

than a continuous charge. The critical blast-hole length increases with the effective strength

of the rock. It is important to ensure that the length of any explosive charge (other than

pocket charges used for breaking collar rock) is at least 20 hole diameters.

Subdrilling is carried out to ensure explosives are placed below the bench floor level to assist with floor grade control The correct amount of subdrilling is critical to the entire operation Too little subdrilling and digging becomes difficult floor grades will be poor and tear on equipment will be increased Too much subdrilling and drilling is adversely affected due to excessive preconditioning...
