• Description:
  This paper presents a nomogram-based method for selecting rock-cutting parameters on a simulated continuous miner. Four different bit geometry-related parameters were considered for the development of a nomogram/graphical model. The parameters were bit spacing, cutting depth, cutting drum rotational speed, and bit tip angle. The experimental study was conducted on an Automated Rotary Coal/Rock Cutting Simulator (ARCCS) in Rock Mechanics laboratories at the West Virginia University. An orthogonal fractional factorial experimental plan was utilized to carry out the experiments. Indiana limestone was used as the test material, the model incorporated a normalized shear load factor, defined as a ratio of shear load component required for removing rock lands/ridges to shear strength of the rock, and specific respirable dust generated during rock cutting. A brief description of dynamic shear components in rock cutting process is provided. Details of dynamic shear strength simulation in the laboratory and its effect on rock lands/ridges removal are discussed. The aids of this model to the operators/owners of continuous miners in selecting optimum rock cutting parameters are also discussed. [Description provided by NIOSH]
