The Royal Netherlands Navy Mine Service (Dutch: Mijnendienst) is a department within the Royal Netherlands Navy that is responsible for keeping Dutch coastal waterways and approaches to major seaport areas mine-free.

[7] During the First World War the minelayers of the mine service laid several defensive minefields to defend the neutrality of the Netherlands.

[2][8] The idea behind the minefields was that it would make it harder for foreign naval ships to enter Dutch territorial waters.

[9] The important role of the mine service during this period led to a increase of new material.
