【 摘 要 】

The requirements of mine drainage water quality indicators in China involve 6 relevant standards of 4 ministries, which four standards are mandatory standards One is recommended standards and one is occupation standard. During the implementation period of the many ministries standards, their "mandatory" has not been fully reflected. There are differences among the 6 requirements of mine drainage water quality, such as a different quantity of water quality indicators, non-corresponding indicators and different limit values of indicators. We analyzed of 6 standards of mine water quality index, this paper tries to perfect the current mine water drainage index requirements and construct the standard system of mine water drainage in China, so as to achieve the goal of mine water discharge and gradually implement "zero discharge". These will contribute to realize the transformation of mine water into waste and integrate unconventional water resources into water resources for unified allocation. These will alleviate the contradiction between supply and demand of water resources, and improve the efficiency and efficiency of regional water resources allocation.
