Drilling and cutting are processes of rock disintegration, which are usually used during exploration and exploitation of solid mineral deposits i.e. during geotechnical and other works. The operational and constructional parameters of machines used for rock drilling and cutting have significant differences but this does not have to be the case with the mechanics of rock disintegration. For example, in processes of determining the quantity and quality of dimension stone deposits, or dimension stone primary blocks exploitation, hydraulic rotary drilling rig, or chain saw are used. Hydraulic rotary drill and chain saw have different operational and constructional parameters but the mechanics of rock disintegration is almost equal. Based on the above stated facts, the following hypotheses have been made: 1. In the processes in which the mechanics (kinematics and dynamics) of rock disintegration by drilling and cutting are the same or similar, there is a significant relationship between certain operational parameters of drilling rigs and machines used for rock cutting. 2. Laboratory testing and verification of the measurement results obtained in real conditions can develop a method of determining the specific energy of rock cutting by measuring the specific drilling energy. The specific energy is a parameter which combines the operational parameters of the machine and properties of the rock, i.e. rock mass into one and it is equal to the total energy required to disintegrate a unit volume of the rock. In order to test and confirm the hypotheses, i.e. to determine the existence and nature of the dependency of the specific energy of rock cutting on the specific drilling energy, extensive laboratory testing and field measurements were carried out. Due to the fact that in the available literature there were no methods neither standards for testing rock cutting specific energy, i.e. specific drilling energy, the author has developed his own method. Laboratory measurements were performed on the linear cutting machine and the laboratory drilling rig, respectively. During laboratory measurements two conceptually different measurement systems were used: the measuring system used for measurement of the electromotor electric power and the measuring system with force transducers (three-axial force transducer and transducer designed for measurement of vertical force and torque). Field measurements were carried out on the dimension stone exploitation field (from which rock samples were delivered for laboratory measurement) on a chain saw and hydraulic rotary drilling rig using the electromotor electric power measurement system. The analysis of the measurement data revealed a strong dependency of the rock cutting specific energy on the specific drilling energy, thus confirming the above stated hypotheses. In addition, the ability to simulate realistic cutting and drilling processes under laboratory conditions was confirmed. Furthermore, based on the analysis of measurement uncertainties of the data, the optimum measurement system was determined (the measuring system for measurement of electromotor electric power). Finally, the guidelines are provided for further laboratory and field measurements using the developed method, which would enable the following: − to determine the value of the specific rock cutting energy at the earliest phase of exploration of the dimension stone deposit, by drilling explorations boreholes, and on such a basis to specify the necessary characteristics of the chain saw used for exploitation of dimension stone − to optimize the operational and constructional parameters of the chain saw and/or hydraulic rotary drilling rig in operational conditions − to influence the energy efficiency of machines − to determine some of the physical-mechanical and mineralogical-petrographic characteristics of the rock which is cut and/or drilled.
