Introduction

Quarrying is a critical process in the construction industry involving the extraction of stone, rock, and other materials from the ground. The methods utilized in quarrying have evolved significantly, encompassing various techniques to enhance efficiency and safety. This article elucidates the primary methods employed in quarrying and highlights solutions provided by Sunward Company.

Methods of Quarrying

The choice of quarrying method depends on various factors including the type of material, geological conditions, and desired production rate. Major methods include blasting, drilling, wire sawing, and channeling.

Blasting

Blasting remains one of the most common and effective methods for quarrying. High-velocity explosives are used to fracture a considerable amount of rock. Critical parameters include:

• Explosive Type: Ammonium Nitrate Fuel Oil (ANFO), Dynamite
• Charge Diameter: Typically between 50-200 mm
• Spacing: Based on rock type and desired fragmentation

Drilling

Drilling is used to create holes for blasting or to directly extract material. It is characterized by:

• Drill Diameter: Ranges from 25 mm to over 300 mm
• Depth: Often between 10 to 30 meters, depending on rock thickness
• Precision: Essential for maximizing yield and minimizing damage

Wire Sawing

This method involves using a wire saw, a thin wire wound with diamond segments, to cut stone or rock. It offers precision and reduces waste:

• Wire Diameter: Approximately 11 mm
• Cutting Speed: Up to 30 m²/hour depending on hardness
• Advantages: Minimal noise and vibration

Channeling

Channeling involves creating narrow cuts to separate large blocks of stone. The process details include:

• Channel Width: Typically 50-75 mm
• Depth: Varies based on block size, generally 1-3 meters
• Application: Primarily in marble and limestone quarries
