La description
Most of stone mining is now intensive drilling in order to control
the direction of its cracking, drilling too close , cause too much
time-consuming and labor-sonsuming , thus reducing the number of
drilling is of great expectations. The compressive strength of rock
is large, the tensile strength is small, take full advantage of the
differences between the two characteristics , if re-inscribed
within a slot drill, just as in the glass, like lines drawn on the
diamond, resulting in stress concentration, can achieve a
multiplier effect, we can reduce the number of drilling but also to
control the cracking direction, thereby greatly reducing production
costs and improve efficiency. LUO Zu-Chun engineer invented the
patent: rock hole Notching device. Experiments show that , after
the notching on the rock, hydraulic splitting machine, static gas
expanders and gunpowder have effect, were shelled, spacing of the
holes on the granite can be opend up **4 times, marble hole spacing
can be released 1.**2 times, thus greatly reducing the cost of
drilling and the medication, first drilling then notching ,
notching time is only 1 / *0 of drilling time, the operation is
convenient and make low cost. Notching Tools can be widely used in
Marble anmd Granite mining, tunnel piercing, smooth surface
blasting.
