Development of automated closed-loop drive upon designing of roller bit drilling rig for open pits [Текст] / Andrey Olegovich Shigin, Anna Aleksandrovna Shigina, Anatolii Vladimirovich Gilev, Sergei Antonovich Vokhmin, Georgii Sergeevich Kurchin // Journal of Theoretical and Applied Information Technology (JATIT). — 2015. — Т. 80 (№ 1). — С. 95-104Аннотация:
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.
