The state APS news agency said it was part of a demining operation in areas where the French army planted mines from 1956 to 1959 during the Algerian conflict.
The latest figure brings to 1,135,084 the number of mines destroyed by the Algerian army.
In 2007 Paris handed over to Algiers details of where its forces laid millions of mines on its borders to prevent members of the Algerian resistance movement from infiltrating Morocco and Tunisia.
Algerian newspapers regularly report mine accidents that particularly affect herders and children.
Algiers is committed to destroying all anti-personnel mines on its territory under the Ottawa Convention.
