6 FAQs about [Does water pressure cause serious damage to the rock drill ]

How does water pressure affect the rotatory speed of hydraulic rock drill?

And the bit surface continuous grind on the wall under the rotary action led to the increase of rotary resistance and drilling resistance; thus, the rotatory speed and drilling speed of hydraulic rock drill decreased with the increasing of water pressure.

How does water jet assisted rock drilling affect tensile strength?

According to crack development conditions, the crack will extend to the free surface causing the rock mass fracture to occur when the stress at the point (r, θ) exceeds the rock tensile strength. In order to reflect the effect of the water jet assisted rock drilling, the bit force assisted with water jet was compared with that of without water jet.

Why does water pressure affect drilling speed?

The reason of the higher the water pressure, the smaller the drilling speed was that the rock breaking depth increased with the pressure increasing; the annular cutting groove was formed in the bottom, as shown in Figure 17.
