Scope

This part of GB 20800 specifies the safety requirements and (or) safety
measures for Group I category M2 reciprocating compression ignition engines
for use in underground workings with methane and/or combustible dust
(hereinafter referred to as internal combustion engines), which are used to
eliminate or limit various dangers and hazards that may occur on internal
combustion engines.
This part applies to the explosion-proof structure design, manufacture and
inspection of internal combustion engines 1).
This part does not apply to Group I category M1 internal combustion engines
that require special conditions.
This part does not apply to internal combustion engines used in places where
explosives are processed, manufactured, stored.
This part does not apply to ignition type internal combustion engines.
