Estimation of Rock Cuttability from Shore Hardness and Compressive Strength Properties

Predicting the performance of large diameter circular saws based on Schmidt hammer and other properties for some Turkish carbonate rocks

“…They are also influenced by the specific gravity of the mineral composition and the compaction of the minerals. Although the importance of density on the estimation of the deformation coefficient obtained from the Shore scleroscope was previously mentioned in [43,44], weak correlations are determined between density, porosity, and deformation coefficient obtained from the Schmidt hammer results in this study.…”

Comparative studies on the performance of a roadheader, impact hammer and drilling and blasting method in the excavation of metro station tunnels in Istanbul

“…(Bilgin et al, 1996(Bilgin et al, , 1997(Bilgin et al, , 2002(Bilgin et al, , 2005Copur et al, 1998;Plinninger, 1998, 1999;Tumac et al, 2007;Ocak et al, 2007;Tuncdemir, 2007;Ocak, 2007Ocak, , 2008. The main objective of this paper is to contribute to accumulated and published data from various tunnelling projects in Istanbul in order to improve predicting the machine performance to schedule and plan the tunnelling projects and determine the excavation efficiency.…”

A Novel Approach for Shearer Cutting Load Identification through Integration of Improved Particle Swarm Optimization and Wavelet Neural Network

“…The drum output torque and rotational speed of constant power shearer were controlled and identified by contact sensing technology of magnetorheological fluid through the simulation test [10]. The cuttability of different kinds of rock and cutting performance of different cutting picks through the basic principle of torque and bending strain reflecting cutting force were studied [11][12][13].…”
