Protecting Workers Through Continuous Training

Mining & Cement

Mining is inherently dangerous. As a result, it comes with an abundance of rules, regulations and safety standards. At Knobelsdorff, we stay abreast of mining protocols and innovations so we’re ready to perform for your operation. We’ve worked in mines extracting metal, coal, limestone, sand and more. We’re versed in open pit and underground facilities. And our trained crews of electricians, foremen and project managers have up to date certifications in MSHA part 46 and 48, as well as training in our rigorous in-house safety program.

In a highly regulated industry, we take safety to the next level

From open pit and shovel mines to facilities that wash and process sand, we have the experience to serve your needs.

Cement & Aggregate

We’ve worked with numerous customers within the cement and aggregate industry. Whether they require electrical design-build contracting services, custom automation and controls panel building services, or ongoing facilities maintenance, we have the tools, resources, and capabilities to meet their unique needs and are ready to take on their projects.

Iron Mine

KE performs electrical and power services in iron mines across the nation, including preventative maintenance on an outdoor lineup of 15kV switchgear, indoor 15kV, 5kV and 480 Volt line-ups. Multiple transformer inspections of 5 MVA and smaller units involved cleaning and repair of units that were leaking, low on oil, needed nitrogen or other issues. We also assisted in installing new switchgear and MCC sections at several locations throughout the mine.

Open Pit Crushed Rock

At multiple locations in Iowa, Minnesota and Missouri, KE has been involved with several crushed rock open pit operations, providing all aspects of electrical construction and maintenance, including installing new conveyors, crushers, switchgear and all other general electrical service needed to keep these busy, hard-working operations up and running.

Sand Plant

KE assesses the safety and compliance of electrical systems at sand plants across the country. This includes completing accurate one-line drawings of sites that include all cable, transformer and overcurrent device information. Work performed also includes engineering review of all defects found on-site and KE providing updated drawings to show corrective actions needed. In one instance, KE also verified the temporary power scheme was connected in a manner that would effectively protect person and property. A three-line drawing was created, and the protection system was reviewed to ensure its safety. Further engineering and code review was completed at the site, and recommendations were made for taking equipment out of service and/or replacing that posed a potential life safety risk.
