Energy-Efficient Air Supply Solution for Xinjiang Tianshan Shengli Tunnel

Project Overview

• Location: Xinjiang, Wuwei Expressway, Tianshan Shengli Tunnel
• Altitude: 2,700 meters
• Tunnel Type: Two-lane highway tunnel
• Total Length: 22,000 meters

Project Requirements

To ensure efficient excavation in high-altitude conditions, multiple tunnel air compressors were deployed along the tunnel. The objective was to deliver sufficient compressed air for rock drilling while reducing energy consumption and operational costs.

Aivyter Solution

To improve energy efficiency, the Aivyter Smart Compressor AWT-10 was integrated into the air supply system at key excavation points.

Phase 1: Pilot Tunnel to Main Tunnel (4,100m)

• Initial Setup: 7 × 132KW (24m³) air compressors
• Excavation Progress: At 4,700m, all 7 compressors were operating, powering 18 × 28 pneumatic rock drills
• Optimization: SYC Portable Diesel Engine Screw Air Compressor deployed 200m from tunnel face
• Result: Only 4 compressors needed to run while meeting full air supply requirements
• Energy Savings: Reduced usage of 2 × 132KW air compressors

Phase 2: Pilot Tunnel to Main Tunnel (7,000m)

• Initial Setup: 7 × 132KW (24m³) air compressors
• Excavation Progress: At 7,600m, all 7 compressors were operating, powering 18 × 28 pneumatic rock drills
• Optimization: Portable Diesel Engine Screw Air Compressor deployed 200m from tunnel face
• Result: Only 4 compressors needed to run while meeting excavation demands
• Energy Savings: Reduced usage of 2 × 132KW air compressors

Energy Efficiency & Cost Savings

By reducing operation from 7 to 4 × 132KW compressors, the project achieved significant energy savings.

Estimated Annual Savings:
132KW × 10 hours/day × 365 days × 4 compressors = 1,927,200 CNY/year (Based on 1 CNY per kWh)
