Mining Electrical Maintenance & Safety Association

Mining Electrical Maintenance & Safety Association


MEMSA was first founded as the organization known for fifty four years as OPMA, the Open Pit Mining Association. 

Roots In 1945 by a group of electrical mining employees in a the Midwest area known for it’s surface coal joined together to trade knowledge and ideas relative to theire work in the mining industry. This original group of men and women miners with an electrical interest has grown through the years to include mine electricians, electrical supervisors, and electrical engineers from a diverse spectrum of mining interests including coal, phosphate, aggregates, and potash and hard rock minerals.

Breadth  Electrical suppliers, utilities, service and repair shops, machine and power cable manufacturers, universities and other support groups of the mining industry have joined with this organization to provide a leading forum for electrical leaders of the mining industry .

In 1999 the Mining Electrical Maintenance & Safety Association, MEMSA,  was formed from the Open Pit Mining Association was renamed to better meet the needs of it’s members in an often rapidly changing industry. 

Mission MEMSA Mission and focus is to advance practical standards of applied electricity and maintenance within the mining industry, and to promote safe practices for protection of operating personnel and equipment by providing a forum for miners with an electrical interest.

Membership is open to everyone involved in mining in North America
and throughout the world.

Electrical Safety is a high priority mining issue as mining moves forward with new and more complex issues to face. MEMSA has adopted electrical safety as a one of the key focuses in the organization. Every MEMSA function and meeting will involve electrical safety as a part of the agenda.
