In Russia and abroad the main volume of drilling in open pit mines is performed by rotary drilling rigs. The article highlights the lack in the technology and equipment of rotary drilling, including the methods to optimize control over basic parameters of the process. The importance of drilling process automation, down to creation of unmanned technologies, is conditioned by a rapid rate of growth in production output and a higher personnel risk in mining under increasingly complicated operating conditions both for the machine and the operator. The need to create the remote-controlled or autonomous rotary drilling rigs is caused by the highly hazardous working conditions. The eff ective remote control of drilling requires a special technical system taking into account the peculiarities of the machine and drilling tools. Drilling in complex-structure rock masses requires continuous adjustment of operating parameters. Thus, drilling in open pit mines should be intellectualized. The article indicates the need to use adaptable rotary feeders in combination with the monitoring system for the structure and strength characteristics of rocks in the array of intelligent control of rotary drilling. It is proposed to use an adaptable sensor with the quick feedback and adaptable damping function. The problem of uncertainty of rock properties is proposed to be handled by monitoring the changes in the rock properties and by implementing stepwise adjustments of drilling parameters using the developed calculation methods.
