Support Activities for Mining

The NAICS code 21311 covers Support Activities for Mining, encompassing a broad range of technical and logistical services that support extraction industries. These activities include equipment maintenance, repair services, site preparation, exploration support, and specialized technical consulting for mining operations. The category involves providing essential infrastructure and technical assistance that enables mining companies to conduct their core extraction activities more efficiently and safely.

The federal contract awards in this category primarily focus on specialized technical services and precision mechanical components for defense and research applications. The Defense Logistics Agency (DLA) has been the predominant awarding agency, with contract values ranging from a few thousand to several hundred thousand dollars. Contracts are frequently set aside for small businesses, with total small business and woman-owned small business set-asides being common. Most awards involve procurement of specialized mechanical components like bearings, shafts, keys, and mounting brackets, typically with delivery timelines between 39-224 days. Performance locations are predominantly DLA distribution centers across the United States, with delivery points including facilities in Oklahoma, California, and Virginia.

Recent federal contract opportunities within this NAICS code demonstrate a diverse range of technical service requirements across multiple federal agencies. The Department of the Air Force, Department of the Interior, and Defense Logistics Agency have posted solicitations for services including remote monitoring units for cathodic protection systems, drilling services for groundwater monitoring, fuel pump maintenance, and precision mechanical component procurement. These opportunities consistently emphasize electronic quote submissions, specific technical specifications, and often include set-asides for small businesses. Performance locations span multiple states, including Alaska, Massachusetts, Rhode Island, and various military installations, reflecting the geographically diverse nature of these support activities.
