The system of manual and automated drilling control systems have been studied. An automated system has been developed which permits simultaneous tracking of variations of structural and strength properties of rock mass during drilling. Technological flowchart of operation of the considered system has been developed. The structure and mathematical dependences have been determined on the basis of which the drilling control system with subsystem of monitoring of rock properties operates. Maximum efficiency of rock destruction during roller drilling of boreholes has been studied as a function of drill bit rotation frequency, time of energy transfer leading to destruction of the required rock amount and feed thrust of working unit. The calculation procedure has been developed of optimum process variables of drill bit drilling of rocks with significant fracturing, lamination and varying drillability factor. Comparative analysis of increase in productivity of drilling rig as a consequence of application of automated system based on adaptive rotating-feeding device. The necessity to equip drilling rigs with automated intelligent system has been substantiated with capabilities to provide duly rapid response of the system to variations of working object properties and maintaining of optimum ratio of the adjusted process variables of "drilling rig--drill bit--rock ore" system. Execution of the aforementioned tasks by intelligent control system will make it possible to reduce drilling expenses and increase in operation efficiency of the mentioned flowchart.
