Self drilling anchor plates
Self drilling anchor system is a bolting solution for difficult ground and rock conditions. The system enables drilling and grouting in one operation, making much saving in job site and project time. Self drilling anchor plate is widely used for mining and tunnel roof support, usually combined together with wire mesh and bolts to form a whole support system. They are compatible with various friction bolts as an important in support system.
The anchor plate is used to ensure that the anchorage point is fixed, usually with solid and dome designs.

6. How to choose the suitable head face of the DTH drill bit?
Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful.
Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate.
Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.
