In tunneling in metal mines, traditional drilling rigs face three major pain points: insufficient reliability of the hydraulic system leads to dependence on imports of key components, frequent failures under harsh field conditions; manual rod replacement is labor-intensive, and there is a high risk of personnel slipping during high-angle drilling operations; the multi-level stabilization device of the Drilling Rig needs to be spliced at high altitude, which poses a risk of rod falling. These pain points directly increase construction costs and safety risks, and restrict the efficiency of deep resource exploration135.
In response to these challenges, the new generation of high-efficiency hydraulic drilling rigs have broken through through three major technological innovations:
Intelligent hydraulic system upgrade: using load-sensitive variable pump and constant power control technology, integrating imported Rexroth/Parker hydraulic components, the system pressure reaches 40MPa, energy consumption is reduced by 30%, and the traditional system is prone to overheating and leakage. 24;
Automated operation chain: equipped with a rear automatic rod change manipulator, the loading and unloading efficiency of a single drill rod (Φ≤114mm) reaches 2 minutes/rod, replacing manual climbing and changing rods; the electronic control upgrade supports wireless remote control (≥30m), realizing automatic adjustment of tool face angle and fault diagnosis57;
Modular stable design: The pressure-cut multi-stage stable device can extend a height of ≥3.5m at a time, and the first-level splicing can reach 4m, eliminating the risk of high-altitude splicing, and the rated support pressure is 21MPa5.
The actual application has achieved remarkable results
A gold mine in Guizhou: Equipped with AD-50 fully hydraulic drilling rig (drilling depth of 40m rock layer/50m soil layer, speed of 300-1200r/min), rope coring was implemented, and the construction period of 500m deep hole was shortened by 40%, and the coring completeness rate reached 98%68;
Huainan Dingji Coal Mine: The CMJ2-30 hydraulic drilling vehicle operation line has made the monthly footage of large-section rock tunnel reach 91m, the rock drilling speed is 0.8-1.5m/min, the noise is reduced by 10 decibels, and the work efficiency is improved by 60%10;
Drilling and Splitting Integration Scenario: Drilling And Splitting Machines realizes drilling-static fracture collaborative operation in extremely hard rock formations, replaces blasting technology, and protects the integrity of the surrounding rock mass2.
Product Features
Dual-mode power: diesel/motor dual drive options, 27HP power output, single-piece disassembly weight ≤100kg, suitable for mountain transportation6;
Translation anchor arm: keep the operating platform horizontal during operation, realize synchronous support of top anchor cables, and shorten positioning time by 50%4.
Operation tips
Lichology adaptation: 43mm straight drill bit is used for medium sandstone layer, and compound wedge-shaped groove cutting technology can increase the circulation footage to 2.2m10;
Solid control circulation: equipped with crawler circulation pump truck (processing capacity 150L/min), realize automatic bagging of drill slag and reuse of wastewater, and reduce water consumption5.
From the technical breakthrough of hydraulic system to the safe reconstruction of human-machine collaboration-this drilling rig is not only a rock-breaking tool, but also the cornerstone of intelligent excavation in metal mines.
