Traditional rebar rock bolts are mostly low yield strenth, for example, 335 MPa which shall lead to more wasting, bad anti-earthquake performances. Anyang Longteng Heat Treament Material Co.,Ltd and China Coal Research Institute CCRI develop heat-treated rebar to improve rebar’s strength.
Advantage:
- *much safer
- *longer lifespan
- *high performance
- *decrease pollution
- *high profit
REAL CASE
Coalmine: Si’Ma Coalmine
Measure: To choose φ18mm 600MPa heat-treated rebar to replace φ22mm 335MPa, while bolts spacing keep the same.
| Rock Bolt Solution | Working Capacity | Weight Per Meter | ||
| 355MPa φ22 | 17.6 Ton | 18% improved | 2.98 Kg/m | 33% saved |
| 600MPa φ18 | 20.8 Ton | 2.00 Kg/m | ||
