1 Scope This standard specifies the technical requirements of metal and nonmetal underground mines (including mines of accompanying radon and its daughters) on under-well ventilation system in safety assessment, design, construction and exploitation process. This standard is applicable to safety assessment, design, construction and exploitation of metal and nonmetal underground mines (including mines of accompanying radon and its daughters). It is also applicable to the part of deep open-pit mine which is exploited by adopting underground shaft and drift. This standard is not applicable to the exploitation of radioactive mineral resources, coal, mine coal-derived pyrite and other paragenetic mineral resources of coal. This standard is not applicable to the exploitation of mineral resources in liquid or gas state like petroleum, natural gas, mineral water, etc. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this standard.
