What the data for this category looks like
Policy and regulatory basis data for mineral mining and processing originates primarily from public documents issued by the Ministry of Natural Resources, Ministry of Emergency Management, local mine supervision departments, and industry standard texts from the National Mine Safety Standardization Association. Data updates align with national or local regulatory policy adjustments, with no fixed schedule. Most documents are in PDF format, and include fields such as issuing authority, document number, effective date, applicable operation links (for example, open-pit mining, mineral processing environmental protection), quantitative indicators (such as dust emission limits, tailings pond safety factor), violation penalty clauses, and more. Some documents include structured clause numbers and chapter divisions.
Constraints on the Deployment and Upgrade Phase
Most mine policy documents are long texts with structured fields. During deployment, configure dedicated document parsing rules to adapt to the format and clause division logic of official documents. Policy updates follow no fixed schedule, so implement incremental synchronization of external policy data sources during the upgrade phase to avoid resource consumption from full re-imports. Policies applicable to different mining areas vary, so divide knowledge base permissions by business unit during deployment. This ensures retrieval requests from different mining areas only return applicable policy content. Configure field-level retrieval rules during deployment to ensure accurate recall of numerical content, as quantitative indicators in policy documents require precise matching during retrieval.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
DB_MAX_LINK | 1000–1500 | Adapts to cross-clause associated reference requirements common in mine policy documents |
STORAGE_S3_ENDPOINT | Configure according to the address of the compliant storage service provider | Ensures compliant storage and access permissions for policy documents |
| Chunk Length | 800–1200 characters | Matches the typical paragraph length of mine policy documents |
| Single Search Limit | Top 8 entries | Covers retrieval recall requirements for multi-clause policies |
REDIS_URL | Local high-availability cluster address | Ensures stability and response speed of retrieval caching |
| Maximum Context | 4000–6000 token | Accommodates complete reference content from multiple policy documents |
Three Common Configuration Errors
- Symptom: When uploading a mine policy PDF, FastGPT returns a parsing timeout error, but the parsing service log indicates the task completed successfully. Cause: The default document parsing timeout configuration does not account for the longer parsing duration of long-text policy documents, leading to premature task termination.
- Symptom: Retrieval results only return a small number of policy entries, and fail to cover all applicable rules for the target mining area. Cause: The single search limit is configured too low, and does not match the retrieval recall requirements for multi-clause policies.
- Symptom: After the knowledge base is updated, retrieval results do not display the latest version of policy content. Cause: The incremental synchronization configuration is not correctly linked to the update trigger mechanism of the external policy data source, so new content is not imported into the knowledge base.
How to Verify Proper Configuration
- Upload a mine safety policy PDF with multiple clauses, and confirm core fields such as issuing authority and effective date are fully preserved in the parsed text. This operation works with FastGPT v4.17.0.
- Submit a query for dust control during underground mining, and verify the number of reference entries in returned results matches the configured single search limit.
- Modify the content of a policy document and trigger incremental synchronization. Wait 10 minutes, then submit the same query to confirm results update to the latest version.
- Check the storage bucket linked to
STORAGE_S3_ENDPOINT, and confirm all uploaded policy documents store correctly and their permission configurations comply with requirements.
