1
Rock Blasting and Explosives Engineering
The terms drillability and boreability are used, often somewhat loosely, to
describe the degree of ease and economy with which a rock mass can be drilled
or bored by a given machine. Thus the terms are mainly functions of the rock
mass and ...
Per-Anders Persson, Roger Holmberg, Jaimin Lee, 1993

Rock Blasting Terms and Symbols: A Dictionary of Symbols and ...
Determination of drilling rate index (relative drillability) from the brittleness 520
value (impact wear) and the SJ value (sliding wear) (after Tamrock 1989). The
following classes for drillability have been suggested, see Table 15. Description ...

Frontiers of Rock Mechanics and Sustainable Development in ...
A brief introduction about experimental measuremeuts of rock acoustic velocity,
drillability, hardness, uniaxial compression strength {UCS) was given in the
paper. A detailed regression analysis of data yielded some correlations of
acoustic ...

Drilling: The Manual of Methods, Applications, and Management
Layers broken as land moved upward or downward Fissility Some rocks (like
shale and slate) have a tendency to split readily along closely parallel planes.
This tendency - called fissility - causes quite different drillability in different
directions.
The Australian Drilling, 1997

Proceedings of the Third World Petroleum Congress Section Ii ...
Hence, the decision was made to use the time interval necessary to drill an equal
depth in each formation — rotational speed and bit thrust remaining equal for
each test — as a basis for comparison to determine "A Drillability Classification of
...

Effects of particle size on the properties and efficiency of ...
Bulkiness, caking, segregation, und drillability were studied in relation to the size
of the particles in fertilizers by making various laboratory tests, some of them with
control of the humidity and temperature of the atmosphere. The behavior of ...
7
Factors affecting the mechanical application of fertilizers ...
The fertilizers of low drillability gave greater variations in delivery because of their
irregular flow from the blade over the rim of the cylinder. The 95 drillability
material flowed so freely that it responded very quickly to movements or
vibrations of ...
Arnon Lewis Mehring, Glenn Arthur Cumings, 1930

Engineering Rock Mass Classification: Tunnelling, ...
The rock drillability or speed of drilling for a blasthole and rock bolting needs to
be estimated to assess the cycle time of tunneling for a given setup of tunneling
machines. Construction time for back grouting and consolidation grouting also ...
R K Goel, Bhawani Singh, 2011
