What is the burning-rate range (seconds per meter) for standard fuse used in mines?

Explanation:
The burning rate is about how long it takes for one meter of fuse to burn, expressed in seconds per meter. For standard mine fuses, this rate is specified as a slow, predictable pace, typically around 100 to 180 seconds per meter. This range is chosen so that the fuse provides a reliable and controllable delay in blasting sequences while still allowing safe handling. If the burn rate were much faster, the timing would be hard to predict and could lead to mis-timed detonations; if it were much slower, delays could become impractically long or unsafe. Therefore, 100 to 180 seconds per meter best matches the standard fuse behavior used in mines.
