Core risks in rainy operation: equipment instability from slippery ground, electrical faults due to water, borehole collapse, personnel slips. Implement strict controls in 6 core aspects per industry standards, with the core principle of avoiding rainy operation unless for urgent exploration (if unavoidable, prepare a special rainproof plan, sufficient waterproof/anti-slip/insulation materials and assign dedicated safety supervisors).

1. Site Reinforcement & Drainage

Pave steel plates/gravel/sleepers on the operation surface; fit ≥0.5 ㎡ anti-slip thick sleepers under rig outriggers (fix with steel wire ropes if needed). Excavate annular drainage ditches (≥20 cm deep, ≥3° slope) around the site; build temporary cofferdams in rainstorms to prevent water/mud immersion of rig key parts and borehole mouth.

2. Equipment Waterproof & Insulation Protection

Electrical system: Fit waterproof covers/rain shelters for motors, distribution boxes and junction boxes; double-wrap connections with waterproof insulating tape; ensure grounding resistance ≤4 Ω; no switch operation with wet hands.
Hydraulic/power system: Seal oil tanks, fit waterproof filters on air vents; inspect pipeline joint sealing and replace leaking rings timely.
Drilling tools & borehole mouth: Install rain shields at the borehole mouth; apply waterproof thread compound to drill pipe threads; wipe drill bits dry for rust prevention after use.

3. Drilling Parameter Adjustment

Reduce rotational speed by 20%-30% and feeding pressure during hole opening; deepen guide hole to 0.8-1 m. Increase mud viscosity and reduce water loss (add wall protection agent if slag return is abnormal). Shorten single drilling round trip by 30% and increase coring frequency.

4. Standardized Operation

Operators wear anti-slip/anti-crush rain boots, waterproof insulating gloves and split raincoats; lay anti-slip mats and set warning signs on-site. Use auxiliary clamps and torque wrenches for drill pipe connection/disassembly. Clarify commands for multi-person coordination; no staying in rig rotation radius; assign extra monitors in poor visibility. No on-site maintenance in rain; handle minor faults in rain shelters after power cut and reseal components.

5. Real-time Inspection & Emergency Response

Inspect electrical insulation, hydraulic oil quality, outrigger fixation and borehole water accumulation every 30 minutes; stop the machine and record abnormalities immediately. Stop operation, cut off power, lift drilling tools above the borehole mouth and evacuate personnel in extreme weather (thunder/≥6 grade winds/rainstorms). For waterlogged electrical components: power off, wipe dry, cold-air dry and restart only after qualified insulation test. For borehole collapse/drill sticking: no forced pulling/rotating; remove slag first, then move drilling tools at low parameters (use casing milling/left-hand thread tools if ineffective).

6. Post-operation Moisture & Rust Prevention

Move the rig to a dry, ventilated place; wipe water/mud off equipment, drilling tools and pipelines. Place desiccants in electrical components; inspect and replace emulsified hydraulic oil timely. Clean, wipe dry, coat with anti-rust oil and store drilling tools/bits by category; seal the borehole mouth with a waterproof cover and set protective signs.
