What is Drilling Rate Prediction in Weathered Limestone about?

This document discusses the prediction of drilling rates for percussive drills in weathered limestone using intelligent techniques. It emphasizes the importance of various rock properties such as rock density, rock quality designation, and geological strength index in determining drilling efficiency, particularly in tropical climates. The study employs multi-variable regression analysis and a hybrid model combining artificial neural networks with biogeography-based optimization to analyze data from 113 dril
