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.
- *much safer
- *longer lifespan
- *high performance
- *decrease pollution
- *high profit
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|
