Technical Choice: A Comparative Analysis of Brand Advantages in Rotary Drilling Rigs —— Intelligence, Power Systems, and Energy-Saving Technologies Amid the global energy transition wave, the photovoltaic industry, as a key pillar of the renewable energy sector, is flourishing at an unprece Read More

As the core equipment for pile foundation construction, rotary drilling rigs pose risks of overturning and collapse during operation. These risks not only may cause equipment damage but also directly threaten the life safety of construction personnel. Combining the risk characteristics obser Read More

     Drill jamming and hole collapse are major risks in rotary drilling rig construction. For drill jamming, handle based on causes: inject mud and reverse at low speed for hard rock, increase mud displacement and lift slowly for slag deposition, impact to detach boulders. For hole collapse, immediately lift the drill and inject high-viscosity mud; ream for minor collapse, fill with clay and gravel for deep collapse, and use modified mud with casing for quicksand. Prevention includes stratum investigation, matched mud, speed control, slag cleaning and drill bit replacement as needed. Read More
