Hard Rock Excavation

Rock Cutting & Drilling Using Diamond Ropes

Controlled cutting and drilling of hard rock formations using diamond rope technology for shafts, tunnels and deep foundations.

Precision Rock Cutting for Complex Underground Works

Many microtunneling, shaft and pipeline projects pass through hard rock, bouldery strata or heavily reinforced concrete. RH YADAV INFRA uses diamond rope cutting and rock drilling techniques to shape these formations safely and accurately, without uncontrolled blasting.

Diamond rope systems allow us to cut large sections of rock and RCC in a controlled manner, while drilling rigs help in creating pilot holes, anchors and blast holes (where permitted). This combination enables the construction of launch shafts, reception pits, deep chambers and access tunnels even in difficult rock conditions.

Our Rock Cutting & Drilling Capabilities

Diamond rope cutting of rock faces, RCC walls and thick concrete structures.
Drilling for anchors, rock bolts and controlled blasting.
Shaft and pit enlargement in mixed and hard rock.
Cutting and trimming of tunnel openings and portal faces.
Interface works with MTBM shafts, culverts and heavy foundations.

Typical Applications

Launch and reception shafts in rock strata.
Deep foundations and well foundations in hard rock.
Tunneling portals and adits.
Cutting of large RCC members and pier caps.

Key Advantages

Controlled cutting with minimal vibration and disturbance.
Ability to handle confined or sensitive locations.
Cleaner profiles and reduced over–breakage.

Execution Methodology

Step–by–step approach for safe and efficient rock cutting and drilling operations.

1. Assessment & Planning

Study of rock quality, joint patterns, access and safety constraints to decide cutting / drilling strategy.

2. Setup & Anchoring

Positioning of diamond rope equipment, sheaves and drilling rigs with secure anchoring arrangements.

3. Cutting & Drilling

Progressive cutting of rock/RCC and drilling of required holes with continuous monitoring of vibration and stability.

4. Removal & Finishing

Safe removal of cut blocks, mucking, trimming and profiling to match design dimensions.

Specialized Equipment & Expertise

Dedicated rock engineering resources to support microtunneling and heavy civil works.

Diamond Rope Saw Systems

High–performance diamond wire / rope saws with variable speed drives for cutting different rock strengths and reinforced concrete.

Rock Drilling Rigs

Hydraulic and pneumatic drilling rigs for vertical, inclined and horizontal holes used for anchors, bolts and controlled blasting (where permitted).

Experienced Rock Crews

Trained operators and supervisors with experience in handling complex rock jobs in coordination with tunneling and civil teams.
