A new powerful and extremely cost-effective alternative to other conventional drilling techniques by controllable and directional holes grooves tools in order to be less holes quantities to cut and split rock at low cost and high drilling efficiency.
Notch hole, get twice the result with half the effort. Nowadays fracture stone most relys on split intensive platoon holes to control fracture direction. If the holes drilled are over dense, it will waste time and labor. Therefore, reducing the number of drilling holes is peoples good expectation.
Rock is of strong compression resistance intensity and weak pull resistance intension, to take full advantage of the obvious difference between the both, if notch in drilled hole, just as draw a line on glass with diamond, it will make the stress concentration to get twice the result with half the effort, reduce the number of drilling holes, improve work efficiency, reduce cost. Therefore invent our company patent: notching tools.
Experiment prove: after notchinghole, it can get good effect with hydraulic splitter, static expand powder or explosive blasting, the distance between holes of granite may lengthen 2-4 times, the marble may lenthen 1.5-2 times, thus reduce drilling and powder cost.Drill first, then notch, notching time is only 0.1 of that of drilling, operate conveniently, low cost.
