In mining operations, the mining anchor drilling machine is a key equipment to ensure the stability of roadways and slopes, directly related to construction safety and mining efficiency. From underground roadways to open-pit slopes, different mining scenarios have varying performance requirements for mining anchor drilling machines. This article analyzes the selection points and operation specifications of mining anchor drilling machines to help you match highly adaptable equipment.

1. Core Role of Mining Anchor Drilling Machine: The "First Line of Defense" for Support Safety

The mining anchor drilling machine consolidates loose surrounding rock into an integrated structure through integrated operations of drilling, grouting, and anchor installation. In underground mine roadway construction, anchor support needs to be completed once every 10 meters of excavation. The efficiency of the mining anchor drilling machine can control the single-cycle time within 1.5-2 hours, 30% shorter than traditional equipment, reducing the risk of surrounding rock collapse.

2. Key Performance Indicators of Mining Anchor Drilling Machine

(1) Drilling Capacity: Hard rock mines require a drilling torque of ≥3500N·m and an impact frequency of ≥55Hz; soft rock mines can choose low-torque models to avoid support failure caused by over-excavation.

(2) Stability: The machine body must be equipped with a hydraulic leveling system to ensure the drilling verticality deviation is ≤1°, meeting the basic requirement of "precision support" for mining anchor drilling machines.

(3) Adaptability: The crawler design must adapt to complex mine terrains with a ground pressure of ≤0.18MPa, satisfying the movement needs of mining anchor drilling machines on muddy and gravel roads.

3. Selection Strategies for Mining Anchor Drilling Machines in Different Mine Scenarios

(1) Underground Roadways: Choose low-profile drilling machines with a body height of ≤2.2 meters. The mining anchor drilling machine must be equipped with a foldable drill arm to adapt to narrow space operations (width ≤3 meters).

(2) Open-Pit Slopes: Prioritize long drill arm models with a drilling depth of over 8 meters. The grouting system of the mining anchor drilling machine must support high-pressure grouting (3-6MPa) to enhance slope stability.

(3) Fractured Zone Mines: Drilling machines must have anti-jamming functions, reducing drill bit wear by automatically adjusting the propulsion force (≤8kN). The drill pipes of the mining anchor drilling machine must be made of high-strength alloy material.

4. Operation and Maintenance Specifications for Mining Anchor Drilling Machine 

(1) Daily Inspection: Check the tightness of hydraulic pipelines before starting the machine daily to ensure the working pressure is stable at 18-25MPa, which is the basic maintenance requirement for mining anchor drilling machines.

(2) Wear Part Management: Inspect drill bit wear after every 300 meters of drilling, and replace immediately when ≥2 alloy teeth are missing to extend the service life of the mining anchor drilling machine.
