Prediction Model of Drilling Performance for Percussive Rock Drilling Tool

Prediction Model of Drilling Performance for Percussive Rock Drilling Tool

This study suggests a method for quantitatively estimating the drilling performance of the down-the-hole (DTH) hammer during percussive drilling of rock surfaces. A pneumatic dynamic model of the DTH hammer was developed that considers the mass flow rate relations representing the orifice opening ar...
