For detail information plz visit at our website: ***** 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.
