Subhet Kumar Dash

Dear Vijaya,

If your rock contains hard minerals, fresh in nature then the penetration is low as compared to the other conditions. if the area of x-section of the bit increases the resistance will increase, which produces noise due to friction and hard hammering action.

If the rock is devoid of joints i.e. massive it is also produce noise.

fractured/more jointed rock (weak rock) produce less noise as compared to other as the energy dissipate through them and rate of penetration is more some time if not struck along joint plane or choked by collapsed rock fragment.

Respected Subhet Kumar Dash sir,

Thank you very much for ur suggestions. Sir, Apart from this is there any reasons is there?.

The lithological variation (porosity, density and the size of grains )cause to increasing the Noise Levels during Drilling Operations.

Respected Ali sir,

Thank your for your response. Is there any other reasons to increasing noise level during rock drilling.
