Hot weather significantly impacts rotary drilling rig operations, reducing efficiency and increasing the risk of equipment failure, material degradation, and health issues for workers. Therefore, scientifically planning construction processes, properly using equipment, and enhancing safety management in high-temperature conditions are essential to ensure smooth project execution. Below are methods and precautions for rotary drilling rig operations in hot weather.
Optimize Construction Schedule
In hot weather, schedule work to avoid peak temperature hours, typically from 11 a.m. to 3 p.m. Morning and evening hours with cooler temperatures are ideal for operations to reduce equipment overheating risks and enhance worker comfort.
Enhance Cooling Measures for Equipment
In high temperatures, key components of the rig, such as the hydraulic system and engine, may overheat, leading to performance decline or failure. Check the cooling system before construction, ensure its proper functioning, and allow adequate breaks for equipment to cool during operations. Shade structures or misting systems can also be used for additional cooling.
Select Suitable Materials
Hot weather can affect the performance of construction materials, such as accelerating the initial setting time of concrete. Use high-performance additives to delay setting time and ensure quick and continuous material transport to maintain workability in high temperatures.
Regularly Inspect Cooling Systems
Before construction, thoroughly check the cooling systems of the rotary drilling rig, including the water tank, coolant levels, and radiator cleanliness. Ensure sufficient coolant levels and clear any debris from radiators to maintain cooling efficiency.
Maintain Lubrication Systems
High temperatures accelerate lubricant oxidation, reducing its effectiveness. Regularly check and replace engine and hydraulic oils, using high-temperature-resistant lubricants suitable for hot conditions.
Protect Electrical Equipment
High temperatures can overheat electrical components or degrade insulation, causing malfunctions. Avoid exposing electrical parts to direct sunlight and use shading or ventilation measures as needed to ensure smooth operation.
Strengthen Heat Protection
Hot weather poses significant health risks to workers. Provide adequate drinking water and heat-relief supplies, and set up shaded areas or temporary rest zones. Workers should wear breathable clothing and take regular breaks to avoid heatstroke.
Enhance Training and Awareness
Conduct safety training for workers to familiarize them with heatstroke symptoms and preventive measures, ensuring they can respond effectively during high-temperature operations.
Prevent Fire Accidents
Hot weather increases fire risks. Pay special attention to fuel storage and fire safety management for electrical equipment. Ensure sufficient fire extinguishers are available on-site and regularly inspect equipment seals to prevent fuel leaks.
Avoid Equipment Overload
High temperatures exacerbate overheating during heavy-duty operations. Reduce equipment workloads as necessary and avoid prolonged high-load operations.
During hot weather construction, promptly address emergencies such as overheating equipment or worker heatstroke. For overheating equipment, stop operations immediately for cooling and inspection. If a worker shows signs of heatstroke, move them to a cool place, apply physical cooling measures, and seek medical attention.
Rotary drilling rig operations in hot weather require a holistic approach, considering equipment maintenance, material selection, worker protection, and construction safety. By adjusting schedules, enhancing cooling and maintenance measures, and safeguarding worker health, the impact of high temperatures can be minimized, ensuring on-time, high-quality project completion.
