Drag pick cutting tests: A comparison between experimental and theoretical results
Journal of Rock Mechanics and Geotechnical Engineering, 2018 This paper aims at reporting the results of a number of drag pick cutting tests on selected igneous rock samples to compare the experimentally determined maximum cutting force (FC′) values with theoretically estimated ones. First, a review on theoretical
