Are Drilling Rigs Different Types? Mountains, Paddy Fields, Hard Rock Layers: How to Choose the Right Equipment?

Drilling rigs are like martial arts masters, each with their own strengths. Choosing the right equipment is crucial for construction in different terrains. Below is a selection guide for three typical terrains.

Terrain 1: Mountains and Hills

Terrain Challenges: Rugged roads, steep slopes, uneven ground, making it difficult for equipment to access and maintain stability.

Core Requirements: Strong off-road capability and excellent stability.

Preferred Equipment: Tracked Fully Hydraulic Power Head Drilling Rig

Why it?

Tracked Chassis: Like a tank, it has strong climbing ability and moves stably on uneven mountainous terrain, making it less prone to tipping over.

Modular Design: In extreme terrain where vehicles cannot pass, it can be disassembled into several parts, transported to the site with small equipment or manpower, and then reassembled.

Comprehensive Functionality: It can flexibly change tools such as down-the-hole hammers and auger bits according to different rock formations, making it highly adaptable.

Terrain 2: Paddy Fields, Swamps, Soft Foundations

Terrain Challenges: Extremely poor ground bearing capacity; ordinary equipment is prone to sinking and cannot operate.

Core Requirement: Minimize pressure on the ground to prevent sinking.

Preferred Equipment: Widened Tracked Swamp Drill Rig

Why It: Extra-wide Tracks: These are its "snow boots." The tracks are made exceptionally wide, like wearing skis, distributing the machine's weight over a large area, thus preventing it from sinking into the mud.

Important Warning: Ordinary tracked or wheeled drill rigs are strictly prohibited from entering this type of terrain; otherwise, there is a high risk of significant losses due to machine entrapment and difficult rescue.

Terrain 3: Hard Rock Layers

Terrain Challenges: The rock is extremely hard; rotary cutting is extremely inefficient, and the drill bit wears out rapidly.

Core Requirement: Use powerful impact force to break the rock, rather than cutting.

Preferred Equipment: Down-the-Hole Hammer Drill Rig

Why It: Principle-Driven Success: It doesn't rely on "grinding," but on "smashing." It uses high-pressure air to drive a "piston hammer" at the bottom of the hole, striking the drill bit at extremely high frequencies, thus breaking the rock. This impact rock-breaking method is far more efficient than other drilling rigs in hard rock formations.

Terrain Type 4: Plains, Ordinary Dry Land

Terrain Challenges: Open terrain requiring efficient operation or frequent relocation.

Core Requirements: Efficiency or mobility.

Preferred Equipment (Choose one):

Rotary Drilling Rig: In soil, sand, and soft rock formations, it is the "king of efficiency," producing high-quality boreholes, suitable for projects with high efficiency and quality requirements, such as building foundations.

Vehicle-Mounted Rotary Drilling Rig: If the construction site is scattered and needs to be moved to the next location immediately after drilling one well, its unparalleled mobility, like a truck, makes it ideal for drilling water wells.

Summary: Quick Selection Guide

Mountainous and Hilly Areas → Choose Tracked Rigs, Stability is Paramount.

Paddy Fields and Swamps → Choose Widened Tracks, Preventing Sinking is the First Priority.

Hard Rock → Choose Down-the-Hole Hammers, Overcoming Hardness with Impact. For flat, dry land: choose rotary drilling for efficiency, and truck-mounted drilling for relocation.

Finally, a strong recommendation: Before making a decision, personally inspect the construction site and understand the underlying geological conditions. Combining information from both the "above-ground" and "underground" areas will allow you to hire the most suitable drilling experts, ensuring the project is completed efficiently.
