Smart Mine Automated Drilling Rig Fleet: CMD60L + CRD3000 at Shendong
Executive Summary
Shendong Mining Area is one of China's core coal production bases — but its geology is complex, gas content is high, and the underground environment is harsh. Conventional manual drilling meant heavy labor, high risk, low efficiency and untraceable data. Jinneng Drilling supplied a complete automated drilling fleet: the CMD60L multi-function automated drilling rig, the CRD3000 automated core drilling rig, and Hurricane-series high-pressure air compressors, integrated with intelligent control, remote monitoring, automatic rod make-up/breakout and automatic parameter optimization — all certified for underground explosive-gas environments and streaming data to the cloud. Since deployment the package has run more than 8,000 hours without a major failure, raised drilling efficiency by over 40%, cut underground headcount, and become a benchmark for smart-mine drilling equipment.
Project Background & Challenge
Underground coal drilling in a gassy, complex mine is one of the harshest drilling environments:
- High-risk ground: Shendong has complex geology, high gas content and harsh underground conditions — putting drillers directly at the face is inherently dangerous.
- Manual work limits: manual drilling was labor-intensive, slow, and produced no traceable record.
- Smart-mine mandate: the operation needed automation and digitalization to cut headcount, control safety and make every hole data-recorded.
Our Solution
Jinneng delivered a matched fleet, not a single rig:
- CMD60L multi-function automated drilling rig: the workhorse for underground production drilling.
- CRD3000 automated core drilling rig: automated coring for geological and gas-hazard investigation.
- Hurricane-series high-pressure air compressors: the air supply for pneumatic drilling across the fleet.
- Intelligent control + remote monitoring: automatic drilling-parameter optimization, unmanned operation and remote control.
- Automatic rod make-up/breakout: rods are handled by machine, not by hand, at the drill face.
- Explosion-proof + cloud-connected: rated for underground explosive-gas atmospheres, with real-time data upload and cloud storage.

Customer Value & ROI
- Fewer people, safer mine: automating rod handling and moving operators to remote monitoring directly reduced the number of personnel exposed in a gassy, harsh environment.
- 40% more drilling output: higher efficiency per rig means more boreholes — for geological exploration, gas control and water-hazard prevention — per shift.
- 8,000 hours without a major failure: fleet reliability is what makes unmanned, unattended operation economically viable underground.
- Data-driven mine: cloud-uploaded, traceable drilling records support safety compliance, planning and hazard prevention — a core requirement of smart-mine development.
FAQ
What is an automated drilling rig fleet for mines?
It is a matched set of automated rigs and support equipment — here the CMD60L multi-function rig, CRD3000 core rig and Hurricane compressors — that drill, core and supply air while operating unmanned under remote monitoring.
What does explosion-proof mean for underground drilling?
In gassy coal mines, electrical and mechanical equipment must be designed so it cannot ignite the surrounding explosive atmosphere; the Shendong fleet is rated for such underground explosion-proof environments.
How much can automated drilling improve mine efficiency?
In this deployment, drilling efficiency improved by over 40%, while the fleet accumulated more than 8,000 operating hours with no major failure and reduced underground headcount.
What makes up a smart mine drilling package?
Automated rigs plus intelligent control, remote monitoring, automatic rod handling, automatic parameter optimization, cloud-connected data and explosion-proof rating — as delivered at Shendong for exploration, gas control and water-hazard work.
