en.Wedoany.com Reported - The open-pit mine drilling rig unmanned system, jointly developed by China Coal Pingshuo Group Co., Ltd. and Dandong Dongfang Measurement & Control Technology Co., Ltd., was officially released in the June 2026 issue of the journal Intelligent Mines. The system achieves a drilling accuracy of ±5 cm, improves drilling efficiency by over 40%, and saves approximately 1.2 million yuan in labor costs per rig annually.

China Coal Pingshuo Group Co., Ltd. is a core coal production enterprise under China Coal Energy Group Co., Ltd., headquartered in Shuozhou City, Shanxi Province, and is one of the largest open-pit coal mines in China. Dandong Dongfang Measurement & Control Technology Co., Ltd. is a high-tech enterprise specializing in intelligent mines and industrial automation. The system is centered on an onboard intelligent control system, adopting a four-layer closed-loop architecture of "perception-decision-execution-management," integrating a remote control center with various perception and execution units to form a full-process automated management and control system. The system integrates core functions such as remote control, automatic leveling, fully automatic drilling, and automatic boom retraction, supporting one-click switching of operation modes.

Under traditional manual operation of open-pit mine drilling rigs, operators must work in harsh environments filled with dust, intense noise, severe vibration, and potential landslide risks, resulting in high labor intensity, frequent safety hazards, difficulties in ensuring hole layout accuracy, and operational efficiency constrained by human factors. This system integrates BeiDou-3 satellite positioning terminals, inertial measurement units (IMUs), 16-line LiDAR, millimeter-wave radar, industrial high-definition cameras, and multiple types of sensors to collect real-time data on rig posture, operational environment, equipment parameters, and precise positioning information.

This research achievement provides a replicable and scalable technical solution and practical model for the intelligent transformation of open-pit mine drilling rigs.
