Shovel Bucket Fill Factor Calculator

Infer actual shovel bucket fill from weighing/independent loose density and heaped volume, values>1 retained as evidence, not forward shovel productivity. Caller independently verifies units, applicability and matching conditions; no operational recipe, safety certification, causal efficacy or legal/resource classification is inferred.

Description

Bucket fill compares observed payload volume with a matched heaped bucket volume.

Bucket fill compares observed payload volume with a matched heaped bucket volume.^[1]

A value above one is retained as an observation to review.

When to use Shovel Bucket Fill Factor Calculator

Use this tool to calculate or review the supplied observations under the stated rules. Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.

How to use Shovel Bucket Fill Factor Calculator and understand its results

Match completed survey or ledger observations by block, segment or stage and confirm their units and boundaries.
Enter observedWeighedShovelPayloadTonnes, observedMatchedLooseDensityTonnesM3, callerVerifiedHeapedBucketVolumesM3, using the field meanings and rules below, then run the tool.
Read observedBucketFillFactors. Inspect nested result fields where present, and review unknown records separately from known matches.
Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.

Input field	Meaning	Value type	Requirement
observedWeighedShovelPayloadTonnes	Observed weighed shovel payload tonnes	list of number	Required
observedMatchedLooseDensityTonnesM3	Observed matched loose density tonnes m3	list of number	Required
callerVerifiedHeapedBucketVolumesM3	Caller verified heaped bucket volumes m3	list of number	Required

Use aligned payload tonnes≥0, loose density tonnes/m³>0 and heaped volumes>0 m³. Divide payload by density and volume; no clipping at one occurs.

fill_i=payload_i/(density_i×heapedVolume_i)

Use the matching field units and the exact boundary, ordering and reference rules above.

Limitations and assumptions

Units, ledger boundaries, survey interpretation and model applicability must be independently established. These summaries do not assign reserve/resource classifications or establish support adequacy, ventilation safety or an operating setting.

Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above.

Alternative or Complementary methods

For a related step, use Loader Bucket Capacity Calculator: Payload, loose density and fill factor can infer an equivalent heaped loader-bucket volume. For a complementary comparison, use Loader Productivity Calculator: Observed loader productivity relates weighed deliveries to matched productive time.
