Rotary Drill Rig Daily Operation – Procedure

Use this checklist to verify readiness of all drill rig components before initiating drilling operations.

Critical Inspection Procedures

Follow these structured procedures to ensure a thorough inspection of your rotary drill rig. These steps are essential for safe and efficient rig operation.

Emergency Stop Testing

  • Ensure area is clear of personnel
  • Start engine and bring to normal idle
  • Activate each E-stop button individually
  • Verify engine shuts down immediately for each test
  • Reset E-stop after each test
  • Document any E-stops that fail to function properly
  • Test remote E-stops if equipped

Hydraulic System Check

  • Start engine and allow hydraulic oil to warm up
  • Set engine to normal operating RPM
  • Cycle each hydraulic function through full range
  • Check for smooth operation with no jerking
  • Listen for unusual noises in pumps or valves
  • Verify no cylinder drift when controls in neutral
  • Check hydraulic pressure gauges in each function

Mast Raising Procedure

  • Check overhead for power lines or obstructions
  • Ensure outriggers are properly deployed
  • Verify all personnel are clear of mast path
  • Slowly raise mast while monitoring alignment
  • Watch for any binding or unusual movement
  • Check mast lock engagement when fully raised
  • Verify mast is plumb using inclinometer

Drill Head Function Test

  • With mast raised and secured, test rotation
  • Verify smooth rotation at various speeds
  • Test head feed up and down full mast length
  • Check head traverse mechanism if equipped
  • Test head tilt function if equipped
  • Verify torque indicator function
  • Test all drill head controls for response

Pre-Drilling Safety Guidelines

Before commencing drilling operations, follow these critical safety procedures to ensure a safe working environment for all personnel on site.

Site Assessment

  • Verify underground utility clearance
  • Check for overhead power lines (maintain min. 20ft distance)
  • Assess ground conditions for stability
  • Identify and mark potential hazards
  • Establish exclusion zones around drill rig
  • Verify adequate workspace for rod handling
  • Check for environmental concerns (dust, noise)

Personnel Briefing

  • Conduct pre-shift safety meeting
  • Review emergency procedures and signals
  • Confirm all personnel have proper PPE
  • Establish clear communication protocols
  • Define individual roles and responsibilities
  • Review safe approach zones for rig
  • Discuss specific hazards for current operation

Rig Positioning

  • Position rig on level, stable ground
  • Deploy outriggers/stabilizers fully
  • Use adequate cribbing under outriggers if needed
  • Check rig levelness with inclinometer
  • Ensure adequate clearance for mast raising
  • Verify safe distance from excavations/trenches
  • Establish clear access paths to/from rig

Drilling Tool Inspection

  • Inspect all drill rods for damage/wear
  • Check bit condition and secure attachment
  • Verify all tool joint threads are clean and undamaged
  • Ensure tools are properly rated for the job
  • Verify handling tools are in good condition
  • Inspect all connection points and adapters
  • Arrange tools in proper sequence for operation
