Summary:
Oil leakage from a mine‑use wet‑spraying carriage during underground operations constitutes a serious safety hazard, necessitating prompt and effective emergency response measures. Properly standardized emergency procedures can prevent the incident from escalating, ensuring personnel safety and preserving equipment integrity.
I. Rapid Assessment of Oil Leakage Conditions
Oil Leak Type Identification
Classify and handle according to the characteristics of the oil spill:
1. Hydraulic oil leakage: characterized by the distinctive odor of mineral oil and a clear, bright oil appearance.
2. Grease leakage: A semi-solid paste that often seeps out from lubrication points.
3. Fuel leak: diesel has a pungent odor and is highly volatile.
4. Gear oil leakage: high viscosity, with a distinctive odor.
Hazard Level Assessment
Classified response based on the severity of the leak:
Minor leakage: seepage rate < 10 Drop / minute
General leakage: A continuous oil streak is formed, but no flow has yet developed.
Severe leakage: oil flow or oil mist is formed.
Hazardous Leakage: Poses a Risk of Fire or Environmental Pollution
II. Emergency Shutdown Procedure
Safety Shutdown Procedure
Standard shutdown procedure:
1. Immediately stop the spraying operation.
2. Move the equipment to a relatively safe area.
3. Cut off the hydraulic system’s power source.
4. Release residual system pressure
On-site safety management and control
Prevent secondary accidents:
Establish a security perimeter and prohibit unauthorized personnel from approaching.
Cut off all possible sources of ignition.
Prepare fire-fighting equipment and stand by.
Ensure the ventilation system is functioning properly.
III. Leak Location and Temporary Repair
Identification of Common Leak Points
Key areas for inspection:
Hydraulic pipeline joints and flange connections
Sealing area of the cylinder piston rod
Valve block mating surface
Pump and motor rotary shaft seals
Temporary Plugging Method
Emergency plugging measures:
1. Pipeline joint leakage: temporarily wrap with sealing tape.
2. Seal failure: Use a dedicated leak‑sealing agent.
3. Hull Cracks: Emergency Repair Using Epoxy Resin
4. Thread damage: Use Teflon tape as an emergency repair.
IV. Handling of Leaks from Different Types of Oil
Hydraulic oil leakage
Special handling for hydraulic system leaks:
Immediately close the corresponding system valve.
Collect leaked oil using a dedicated container.
Record the rate of oil level decline.
Check the change in the pressure gauge reading.
Fuel leak
Fuel System Leak Handling:
1. Immediately close the fuel valve.
2. Use explosion-proof tools for handling.
3. Use oil-absorbing cotton to control the spread.
4. Enhance on-site ventilation and air exchange.
V. Safety Protection Measures
Personnel Safety Protection
Operator protection requirements:
Wear oil-resistant gloves and safety goggles.
Wearing antistatic workwear
Use non-slip safety shoes.
Avoid direct skin contact with oils.
Environmental protection measures
Preventing environmental pollution:
Use oil-absorbent pads to contain the spread of oil.
Install a cofferdam to prevent external leakage.
Prepare a dedicated collection container.
Promptly remove contaminated rock layers.
VI. Preparations Before Maintenance
Maintenance Condition Confirmation
Pre-repair inspection:
Confirm that the system has been fully depressurized.
Detecting combustible gas concentration
Prepare explosion-proof maintenance tools.
Clear and maintain the work area.
Technical Documentation Preparation
Technical documentation required for maintenance:
1. Hydraulic System Schematic Diagram
2. Seal Model Manual
3. Installation Torque Parameters
4. Special Tool Instruction Manual
VII. Requirements for Follow-up Handling
Maintenance Quality Verification
Post-repair inspection and testing:
Conduct pressure testing to verify the sealing performance.
Check the reliability of all connection points.
Confirm that there is no leakage.
Record maintenance data
Improvement of preventive measures
Prevent further leakage:
1. Analyze the cause of the leak.
2. Improve weak links
3. Strengthen routine inspections.
4. Improve the emergency response plan.
Conclusion
Emergency response to oil leaks on mining wet‑spraying rigs requires a rapid response and standardized procedures. By establishing a comprehensive emergency plan, equipping facilities with the necessary emergency equipment, and enhancing staff training, the impact of oil‑leak incidents can be effectively mitigated. It is recommended that mining enterprises develop detailed emergency response protocols, conduct regular emergency drills, and maintain well‑stocked emergency supplies, ensuring that oil‑leak incidents can be addressed swiftly and efficiently, thereby minimizing losses and safeguarding safe production in the mine.
