Abstract
The purpose of the research is to study and systematize relevant scientific works on monitoring and telemetry systems for operating parameters of borehole core drilling in glaciers and subglacial rocks with electromechanical cable-suspended drills. The study includes a review of monitoring and telemetry systems for operational parameters of core drilling with electromechanical cable-suspended drills, which are used by domestic and foreign specialists when drilling wells in ice and subglacial rocks on islands in the Arctic and Antarctica. Based on the results obtained, a unified concept of the considered systems is defined and their features are outlined. A functional block diagram of a monitoring and telemetry system for operating parameters of core drilling with electromechanical cable-suspended drills is proposed. Taking into account the identified features and applied technical solutions in the monitoring and telemetry systems created by domestic and foreign specialists, the authors of the article formulate the requirements for the monitoring and telemetry system of the core drilling of rocks using a reciprocating rotary method. These requirements will be taken into account when developing a system for monitoring and telemetry of the reciprocating rotary method of drilling boreholes in subglacial rocks, which is one of the stages of the research conducted as a part of development and justification of the technology of subglacial rock core sampling in Antarctica by a dynamically balanced cable-suspended drill.
