Scope
Main technical content: This document specifies the terms and definitions, construction requirements, construction plans, auxiliary facilities, electrical and communication systems, monitoring and control systems, energy conservation, and fire protection for the construction of underground mobile gas extraction pump stations. This document is applicable to coal mines where the capacity of surface gas extraction pump stations is insufficient, and new construction (expansion) is limited, requiring the establishment of underground mobile gas extraction systems to increase the mine's extraction capacity.
