Drill Blast Drill Blast –– Blast Pattern DesignBlast Pattern Design One of the basic principles of designing the configuration and sequential detonation of blastholes in a one blast, is the presence of a free face ... The following are the more common explosives used in hard rock excavation:
design. Rock properties often vary greatly from one end of a construction job to another. Explosive selection, blast design, and delay pattern must consider the specific rock mass being blasted. Characterizing the Rock Mass The keys to characterizing the rock mass are a good geologist and a good blasting driller. The geologist must con
PRINCIPLES OF DESIGN FOR HARD ROCK QUARRIES. In a hardrock quarry, waste may arise from the following sources: • Soil and overburden; • Interface materials (weathered bedrock) at the top of the deposit; Pennsylvania Quarries | Stone Quarry in Pennsylvania.
The major mechanisms of rock breakage result from the sustained gas pressure buildup in the borehole by the explosion. First, this pressure will cause radial cracking. Such cracking is similar to what happens in the case of frozen water pipesa longitudinal split occurs parallel to the axis of the pipe. CHAPTER 13.
