Which is better for mining ASCE 30 track or S20 light rail?

 

For most modern mining operations, the DIN 5901 S20 rail is the superior technical choice due to its 100.00 mm height, which provides significantly more vertical stiffness than the ASCE 30 lb rail (height of ~79.38 mm). While the ASCE 30 is heavier at approximately 14.88 kg/m (30 lbs/yd) compared to the S20's 19.80 kg/m, the S20's taller profile acts as a more rigid beam. This prevents the rail from sagging between sleepers-a critical advantage in underground mines where the floor is often uneven.

Both ASCE 30 and S20 light rail are suitable for mining applications, with the better choice depending on the specific region, existing infrastructure, and load requirements.

 

• ASCE 30 (30 lb/yd) Rail is generally better for operations in North/South America and areas adhering to American ASTM standards.

 

• S20 (DIN 5901) Rail is generally better for operations in Europe, Asia, or Africa following European DIN standards.

 

Detailed Comparison for Mining:

 

 

• ASCE 30 Rail: Designed for medium-load industrial and underground mining applications, particularly as temporary haulage tracks, due to its easy installation and adaptability to different loads (e.g., 55Q steel grade). It is often used for mining carts and narrow-gauge underground transport.

 

• S20 Light Rail (approx. 20 kg/m): Widely used for underground mining operations and industrial settings in European-standard regions. It is frequently used for underground mining applications where small locomotives or carts are used, providing a balance of strength and portability for shifting tracks.

 

Key Factors for Decision:

 

• Availability: Choose based on which standard is more readily available in your region (American standard vs. DIN/European standard).

 

• Weight/Capacity: ASCE 30 (30 lbs/yd is ~15 kg/m) is technically lighter than a 20 kg/m DIN S20 rail. For slightly higher loads, S20 or even ASCE 40 may be preferred; for lightweight temporary tracks, ASCE 30 is highly efficient.

 

Which Material Strength is Required for Mining Environments?

 

Both rails must be ordered in high-quality grades to survive the abrasive conditions of a mine. For the S20, 55Q grade steel is the standard, providing a RAIL S20 MATERIAL STRENGTH of ≥ 710 MPa and a hardness of 200–240 HB. ASCE 30 rails are typically manufactured to ASTM A1 standards.

 

 

55Q	Mechanical property						Chemical composition(%)
	Yield strength		Tensile strength		Elongation	Hardness	C	Si	Mn	S	P
	MPa	kg/mm²	MPa	kg/mm²	min	HBW				≤	≤
	≥	≥	≥	≥		≥
			685	69		197	0.50-0.60	0.15-0.35	0.60-0.90	0.04	0.04

 

Because the S20 is taller, it is more efficient at handling the vertical dynamic shocks of ore cars. However, in extremely wet or acidic mines, the thicker web of a heavier ASCE rail might provide a larger corrosion allowance, though the S20 rail profile remains the benchmark for modern, high-efficiency transport loops.

 

FAQ

 

Q: Can I use S20 rails if my current mine locomotives are designed for ASCE tracks?

A: You must check the wheel tread width. If your wheels are wider than 30.00 mm, they may overhang the S20 head, causing rapid "mushrooming" of the rail edges. However, if the wheel profile matches, the S20's 100.00 mm height will provide a much smoother and more stable ride than the shorter ASCE 30.

 

Q: Why is the S20 rail weight 19.80 kg/m while ASCE 30 is only ~15.2 kg/m?

A: The S20 is a "heavier" light rail despite the "20" in its name. It contains more steel per meter, which is why it offers superior RAIL S20 MATERIAL STRENGTH and durability. For a long-term mining project, the extra 5 kg of steel per meter in the S20 is a vital investment in safety and reduced maintenance.

 

Q: Does GNEE RAIL provide pre-drilled holes for ASCE 30 rails?

A: Yes, we provide CNC drilling for both DIN 5901 and ASCE standards. We can drill the holes exactly to your project's rail drawing to ensure that the fishplates fit perfectly, preventing the "clapping" of rail ends that lead to web failure in underground tunnels.

 

Q: Which rail is easier to install manually in a confined tunnel?

A: The ASCE 30 is lighter and therefore easier to lift by hand. However, the S20's 19.80 kg/m weight (about 115kg for a 5.8m section) is still manageable for a two-person team. The tradeoff is that the S20 requires fewer sleepers due to its higher vertical stiffness, potentially saving labor on the overall installation.

 

Q: How does the price per ton compare between these two types?

A: The price per ton is usually similar as they are both hot-rolled products. However, because the S20 is heavier, your price per meter will be higher. This is offset by the fact that the S20 is a much more durable S20 rail profile that can handle higher frequencies of ore transport without deforming.
