Khanij Mitra buyer's checklist for Uttarakhand mining weighbridges

For Uttarakhand mining lessees, DMG officers, and weighbridge vendors

If you run a mining lease in Uttarakhand — whether sand, gravel, limestone, magnesite or any other minor mineral — you are almost certainly required to use Khanij Mitra's e-Rawanna system at every despatch weighbridge. Buying a weighbridge with proper Khanij Mitra integration is not optional, but the actual decision is full of vendor jargon. This checklist exists so a procurement officer or mining-lessee owner can verify whether a quoted vendor + software combination will actually meet the portal's requirements before the first truck rolls.

What Khanij Mitra is

In plain terms: every truck leaving your mining yard with mineral on board must carry an electronic permit (e-Rawanna). The permit is generated at the weighbridge at the moment the truck completes weighment. If the integration between your weighbridge software and Khanij Mitra is working, the permit is generated automatically. If it is not, your operator manually logs into the portal to issue it — which slows the yard, adds errors, and is exactly what the system was designed to eliminate.

Why e-Rawanna exists and what it solves

Before Khanij Mitra went live, despatch was paper-based. Each truck got a hand-written form filled in by the yard clerk and stamped by the lessee. The Mining Department reconciled against royalty payments — a process that took weeks, was open to inflation of weights, and was the root of most royalty-payment disputes.

e-Rawanna replaces this with a real-time digital record. The benefits, in DMG's framing:

• Truck weight at the time of dispatch is captured by an indicator, not written on a form.
• The portal calculates royalty + cess automatically against the lease rate and mineral type.
• The e-Rawanna pass is checked at every checkpost on the route — no pass = stopped truck.
• End-of-month royalty reconciliation is automatic; lessee can run reports for any period.

Who has to use it

Every mining lease in Uttarakhand for the following mineral categories is required to use Khanij Mitra-issued e-Rawanna at every despatch:

• Minor minerals: sand, gravel, boulder, stone (limestone, marble, slate, sandstone)
• Magnesite, soapstone, bentonite, gypsum
• Any other minor mineral notified under the state minor mineral rules

Major minerals (coal, iron ore) are governed by the central Mines & Minerals Act and use FCI Hafed-adjacent systems rather than Khanij Mitra. If you have a mixed-mineral lease, you may need both.

Pre-purchase compliance checklist

Before you sign a weighbridge purchase order with any vendor — Eagle Weigh or anyone else — verify these eight items.

1. Vendor has a documented Khanij Mitra reference implementation. Not a marketing claim. Ask for the names of two mining lessees the vendor has integrated. Call one before signing.
2. Indicator + software handles two-pass weighment for trucks without registered tare. First-time trucks need an empty-truck second weighment. Vendors who only support single-pass workflows fail at this on day one.
3. Indicator captures truck registration number reliably. Sounds basic but plenty of yards have OCR failures in low light or with grimy plates. Manual entry must be possible and must validate against the portal's vehicle master.
4. Software supports the standard royalty-rate matrix. Rates vary by mineral, by lease, sometimes by year. The software must pull the right rate from the portal, not let the operator type it.
5. Offline-queue capability. Internet at the yard drops occasionally. If a despatch happens during an outage, the slip must queue locally and post to Khanij Mitra when connectivity returns — without manual intervention.
6. Checkpost reprint. If a truck is stopped at a checkpost and the original pass is lost, the software must let your yard reprint the same e-Rawanna with the same portal reference. Not a fresh permit — a reprint.
7. Audit log of every portal interaction. Every API call, every retry, every operator override — recorded. This is what protects you if a checkpost disputes a permit.
8. Vendor's annual support includes Khanij Mitra API updates. The DMG updates the portal API roughly once a year. Updates need to ship without you paying extra.

How to get portal credentials

Khanij Mitra credentials are issued to the lessee, not to the software vendor. You need to apply through your local DMG district office. The process:

1. Submit a credential request to the District Mining Officer (DMO) with your lease number, lessee PAN, lessee bank account for royalty payments, and the weighbridge yard address.
2. DMO verifies the lease is current and royalty payments are up to date.
3. DMO forwards the request to the state DMG IT desk for credential provisioning.
4. Credentials issued via email within 2-3 weeks. They include a portal username, a one-time activation password, and an API client-ID + client-secret pair if the integration uses API mode.
5. You share the API credentials with your weighbridge software vendor for configuration. Username + activation password stay with the lessee.

Hardware compatibility checklist

Khanij Mitra does not specify hardware. But the portal's data quality requirements mean some hardware combinations work better than others:

• Indicator: 24-bit ADC minimum (16-bit indicators introduce too much rounding error at the bottom of the scale). Eagle CFR-02 + most equivalent terminals.
• Memory: 16,000-record memory minimum so a 30-day connectivity outage does not lose data.
• RS-232 + USB Serial: for the Windows machine connection.
• SMS facility: useful for driver-confirmation, not strictly required for portal integration.
• Printer: dot-matrix is the default and matches the FCI/DMG format expectations. Some yards add laser as a backup.
• UPS + power stabiliser: not optional in Uttarakhand sites where grid power is variable. Add 30 min runtime UPS minimum.

What integration really means at your yard

"Khanij Mitra integration" is a phrase vendors use loosely. There are three real integration depths:

1. Manual mode. Operator types weighment data into the portal in a browser tab. Software does not talk to the portal at all. Slow, error-prone, technically not "integrated" but vendors sometimes claim it.
2. One-way push. Software pushes weighment data to the portal via API but does not read responses. The e-Rawanna pass is generated separately in the portal and printed manually. Better than nothing but still requires two screens.
3. Bidirectional API integration. Software pushes the weighment, receives the e-Rawanna pass back with a portal reference, prints the pass directly on the same slip. This is what the DMG intends; this is what passes vendor demonstrations.

Only bidirectional integration meets the requirement that an operator can do a full weighment + permit + truck out in under 90 seconds. EagleOS provides bidirectional integration; ask any vendor you are evaluating to demonstrate the same.

Realistic timeline from purchase to live sync

Realistic total: 4-5 weeks from PO to live sync, with the credential request the dominant bottleneck.

Six vendor red flags to watch for

1. Vendor cannot name a single Uttarakhand mining-lessee customer. Walk away. They have not actually deployed Khanij Mitra integration.
2. Vendor wants to use a third-party gateway for the Khanij Mitra API. Adds a third party to your data flow. If the gateway goes down your yard goes down. Direct integration is the safer choice.
3. Vendor charges per e-Rawanna issued. Khanij Mitra usage is free for lessees. A vendor charging per-permit is reselling something they should be including.
4. "Cloud-based" software for a mining yard. Mining sites have variable connectivity. Cloud-only software degrades the moment the network drops. Always pick offline-first.
5. Vendor wants to attend every checkpost dispute as paid support. Should be included in annual support, not billed per visit.
6. Vendor doesn't mention the DMG annual API updates. They either don't know about them or are planning to charge you separately. Ask explicitly: "is the next DMG API update included in my support cost?"

Penalties for non-compliance

Operating without a valid e-Rawanna pass on a truck dispatching minor minerals from a Uttarakhand mining lease is an offence under the state minor mineral rules. Specific penalties vary by district enforcement but commonly include:

• Truck detention at checkpost until a valid pass is issued
• Fines per truck per day of unauthorised despatch
• Royalty re-assessment with penal interest
• For repeat offences, lease suspension proceedings

The cost of getting the integration right at purchase time is small compared to the cost of fines + delays from getting it wrong. The checklist above is what we would walk through with any new mining-lessee customer.
