Abstract:

The content of the article outlines the regulations on coal mine vvaste water quality and coal sorting plants of some countries in the vvorld, and provides the scientiíic basis used to propose draft regulations on substances. coal mine vvaste vvater and coal ^ sorting plant. Results after analyzing the nonconíormity of QCVN 40: 2011/BTNMT when applied to coal mine wastewater and í coal sorting plant together with the Ị introduction of QCVNs of other specific industries and results determine specitic pollution parameters in coal mine waste water and coal sorting plants. Since then, it Ị is necessary to establish QCVN on coal mine vvaste water and coal sorting plant, with the indicators to be monỉtored for pollution including pH, TSS, BOD5, COD, Fe, Mn and I total mineral
