Notice on safe operation procedures for drilling rigs!

I. Purpose

The objective of this document is to regulate employee conduct, establish standardized operational procedures, and guarantee safety for both personnel and equipment.

II. Scope

This guideline is applicable to the operation and maintenance of the drilling rig.

III. Risk Identification

Potential hazards include fire, burns, falls from heights, being struck by objects, collapses, mechanical injuries, dust exposure, and noise pollution.

IV. Protective Equipment

Essential protective gear consists of safety helmets, protective clothing, safety shoes, gloves, earplugs, and dust masks.

V. Operation Procedures

1. Pre-Operation Checklist

1. Before initiating work, the drill rig must undergo a thorough inspection. This includes checking engine oil, hydraulic oil, air compressor oil, pneumatic tool oil, and coolant levels. Ensure everything is topped off, and inspect for any signs of oil leakage or damage. Do not start machinery that shows any faults.
2. Upon powering the equipment, verify that the lights, horns, wipers, indicator instruments, emergency stop switches, fault display lights, and alarm buzzers are functioning properly.

2. During Operation

1. Once started, monitor all instruments closely to ensure they are operating within the specified ranges for oil pressure, water temperature, current, and voltage. Examine the hydraulic and air supply systems as well.
2. The machinery should idle for 3-5 minutes before being placed under load. It is strictly prohibited to engage full-load operations immediately after start-up. Always buckle the seat belt before operating the equipment.
3. Limit engine start times to a maximum of 30 seconds, with at least a 2-minute interval between each start.
4. The engine should not idle for more than 5 minutes, and avoid abruptly shutting down a high-speed engine.
5. During operation or driving, no individuals should be seated or standing anywhere on the drilling rig except within the cab area.
6. Prior to commencing work, ensure a thorough check of the drilling location’s rock formation for stability. Maintain a distance of at least 3 meters between the crawler and the edge of any slope to mitigate the risk of landslides.
7. Keep detailed records of drilling activities. If a cave is encountered, document its location and notify mining technicians, marking the area and issuing warnings. Be vigilant for potential issues such as the drill becoming stuck or losing drill rods. In case of encountering a significant cave, evacuate immediately.
8. When relocating the drilling rig, carefully inspect the terrain to ensure a clear path free of obstacles and hazards, such as cracks and caves. Movement is prohibited on slopes exceeding 15 degrees. The driver should signal using the horn before moving the equipment, ensuring nobody is present in front of or behind the crawler. If navigating steep slopes, the drill frame must be lowered and operated under the direction of a designated person. Move cautiously to maintain stability, avoiding sharp turns and soft ground.
9. The Jinke drilling rig is not allowed to remain on steep ramps for extended periods, and traveling long distances at night is prohibited. Prior to adjusting the rig, ensure that non-operating personnel are clear from potential hazard zones. Severe weather conditions, including thunderstorms and strong gusts, necessitate operation suspension, leveling out the drill rig and switching off the main power.
10. During operations, verify the stability of the rock formation, prohibiting cross-operation of the drilling rig. When the equipment is stable, ensure the distance from the jack or grounding points to the top edge of a slope is no less than 2.5 meters and that no equipment extends beyond this line; particularly, the drilling rig’s angle to the slope must remain above 45 degrees for the initial drill row.
11. Under no circumstances should the water tank cover be opened while at high temperatures.

3. Post-Operation and Maintenance

1. After halting drilling rig equipment, maintain a safe distance of over 20 meters from any slopes, and aim to stop on level ground.
2. Post-operation, ensure that the operating handle is in the neutral position, turn off the engine, and check for any oil or water leaks around the machinery, recording any findings. Remove the ignition key, disconnect the battery switch, and secure the vehicle by locking the doors.
3. Adhere strictly to maintenance protocols and lubrication schedules, routinely inspecting, maintaining, and lubricating the equipment.

VI. Emergency Measures

1. If a fire occurs in the engine, electrical systems, etc., stop the vehicle immediately, power off the engine, swiftly cut off electricity, utilize dry powder fire extinguishers, and alert superiors.
2. For minor burn injuries, rinse the affected area with copious amounts of clean water for at least 30 minutes, apply burn ointment, and seek medical attention as needed.
3. For any personal or equipment-related accidents, report them immediately and initiate self-rescue and recovery efforts.
