According to Mining Regulation, quarry reclamation after mining has to be realised in order to use mined area for another purposes.  In reality, due to many reasons, among many closed quarries, this mission was only executed for some of them. Moreover, environmental impact assessements have not been applied for all of closed mines as well as reclamed mine yet.. Through initial survey, it is showed that some of them have environmental problems and unsafety. The paper focus on survey and analysed sample results of 3 closed mines (Dong Hoa, Tan Phuoc Khanh, and Binh An) in Di An, Binh Duong province in order to analyse their actual states as well as  propose management methods.
