NACE 09.9 – Support Activities for Other Mining and Quarrying | Public Tenders

Definition: NACE 09.9 covers services provided on a contract basis for mining activities other than petroleum and natural-gas extraction. These include mining-technical services for coal, ore and mineral mining, mine safety, ventilation and other mining support services.

Legal basis: NACE Rev. 2 (Regulation (EC) No 1893/2006) · Last updated: January 2026

What does NACE 09.9 cover?

NACE 09.9 (Support activities for other mining and quarrying) classifies specialist mining service companies outside the oil and gas industry — a segment that gains relevance in public procurement mainly in connection with state-owned mining enterprises, restoration measures and mining-authority tasks.

Group 09.9 within Section B (Mining and quarrying) and Division 09 (Mining support service activities) is broken down into the following classes:

Public contracting authorities relating to NACE 09.9 are state mining enterprises, mining supervisory authorities, municipalities in former mining regions and federal authorities that commission old-mine rehabilitation and mine-safety supervision.

Public Tenders: Scope of NACE 09.9

Mining-technical services for state-owned mining enterprises and old-mine rehabilitation are the most important tender segments of NACE 09.9 — with growing importance in the context of mining wind-down and after-care of disused installations.

Typical types of contract

• Mine safety and mine ventilation: Gas measurement, ventilation technology, explosion protection in mines
• Mining-technical services: Gallery support, gallery maintenance, shaft construction and repair
• Mine surveying: Surveying engineering, GPS surveying underground, deformation measurement
• Old-mine rehabilitation: Day-collapse stabilisation, well plugging in old mines, mine-water treatment
• Mining-damage assessment: Expert reports on mining damage to public infrastructure (roads, buildings)
• Mine rescue service: Mine rescue equipment, training, exercises for mine rescue services
• Environmental monitoring: Subsidence measurements, groundwater monitoring, emissions measurement for disused collieries

Thresholds and procedure types

Mining-technical services for state contracting authorities are subject to classical procurement law unless the contracting authority is a utility contracting entity. EU threshold for service contracts: EUR 215,000 (federal authorities) and EUR 215,000 (other public contracting authorities, as of 2024/2025). Mining-damage expert reports and rehabilitation services are frequently tendered under VOF/VgV (professional services) or as construction work under VOB/A.

Relevant CPV codes for NACE 09.9

CPV codes enable targeted searches for mining-service and old-mine rehabilitation tenders on procurement platforms.

Current tenders can be found on TED (Tenders Electronic Daily) and on national procurement platforms and the portals of mining supervisory authorities.

Who is NACE 09.9 relevant for in procurement law?

Public contracting authorities

Mining supervisory authorities (state mining offices in Germany, WKÖ-affiliated mining authorities in Austria) award expert reports and safety inspections. State-owned contaminated-land companies such as LMBV (Lusatian and Central German Mining Administration) commission extensive rehabilitation services for former lignite regions. Municipalities in mining regions (Ruhr area, Saarland, Lusatia, Mährisch-Ostrau area) commission mining-damage reports and infrastructure maintenance. Federal institutes (BGR, BAuA) award research and monitoring contracts on mining safety.

Companies and bidders

Mining service providers wishing to participate in public tenders typically require:

• Authorisation: Mining-surveying approvals (state-certified mine surveyors), mining-law permits
• Technical capacity: References for comparable mine-safety or rehabilitation projects
• Safety evidence: Mine-rescue-team certifications, explosion-protection concepts (ATEX)
• Economic capacity: Sufficient capacity and insurance cover for special risks
• Certifications: ISO 9001, ISO 14001, SCC (Safety Certificate Contractor)

NACE 09.9 in context: Section B and Division 09

NACE 09.9 complements the oil/gas-specific drilling services within Division 09 with the broad range of mining-technical services for all other mining areas.

• NACE B – Mining and quarrying: Parent section
• NACE 09.1 – Support activities for petroleum and natural-gas extraction: Related group for oil/gas services
• NACE 05.1 – Mining of hard coal: Coal mining as contracting authority
• NACE 07.1 – Mining of iron ores: Metal-ore mining as contracting authority
• NACE 08.1 – Quarrying of stone, sand and clay: Quarry and gravel-pit services

Frequently Asked Questions about NACE 09.9 and Public Tenders

Which companies fall under NACE 09.9? Specialist mining service providers that supply mining-technical services such as mine safety, ventilation, mine surveying or shaft restoration. Mine-surveying practices and mining-technical expert offices are typical representatives of this group.

What is old-mine rehabilitation and how is it tendered? Old-mine rehabilitation includes the protection and removal of mining damage from disused installations — day-collapse repairs, shaft fillings, gallery seals. Depending on scope, these services are tendered as construction (VOB/A) or service contracts (VgV), frequently by specialist state companies such as LMBV.

What is the role of the mine surveyor in public tenders? Mine surveyors are state-licensed experts for pit and underground geometry. Their services (mine surveying, deformation monitoring, mining-damage expert reports) qualify as professional services and are tendered under VgV §74 et seq. State licensing is an eligibility prerequisite.

Where do I find tenders for mine rehabilitation and mine safety? On TED with CPV code 90721300 (mining-damage rehabilitation) and on the portals of LMBV (lmbv.de), the state mining offices and municipal contaminated-land programmes. The Federal Ministry for Economic Affairs and Climate Action (BMWK) also awards mining-research contracts through its funding portal.
