Selection of high-strength dimension stone cutting method, considering natural jointing

The authors prove feasibility and efficiency of high-strength stone wire saw cutting in rock mass with subvertical and low-angle joints as well as drilling-and-wedge cutting of stone into marketable size blocks on the working site. The article presents and substantiates the procedure for rational selection of technology for high-strength stone preparation for cutting, considering geological conditions (shape of mineral body, orientation and spacing of joints), local temperature, as well as physico-mechanical properties and mineralogical composition of rocks.
