Geltungsbereich und Anwendbarkeit
This standard applies to the calculation, assessment, and energy consumption control of coal underground mining enterprises. It specifically targets the energy consumption per unit product of raw coal in underground mining operations. It is not applicable to open-pit mining operations. It references GB/T 28398-2012 for statistical specifications.
Technische Anforderungen
GB 29444-2012 establishes mandatory energy consumption limits for coal underground mining. It categorizes requirements into limits for existing facilities, access values for new enterprises, and advanced values for technological improvement. Compliance with these limits is legally required for all underground mining operations in China. The standard defines the comprehensive energy consumption per ton of raw coal produced. It distinguishes between main production energy consumption and auxiliary production energy consumption, requiring both to be converted into standard coal equivalents (kgce/t) using specific calorific values. To account for varying operational conditions, the standard introduces a calculation method utilizing multiple conversion coefficients. These coefficients adjust the final energy consumption value based on specific mining parameters, including mining conditions and technology, transportation distance, mine gas grade, and mine water inflow.
Prüfverfahren
The standard does not specify traditional laboratory testing methods but outlines an energy consumption calculation and statistical framework. Enterprises must establish an energy statistical system in accordance with GB 17167 for energy metering. Regular monitoring of major energy-consuming equipment is required, referencing specific methods such as MT/T 1000 for industrial boilers and MT/T 1001 for hoists to ensure economic operation.
Häufige Fragen
What products are regulated under GB 29444-2012?
The standard regulates the energy consumption of raw coal produced through underground mining operations. It applies to both existing and newly constructed coal mining enterprises.
Are the energy consumption limits in GB 29444-2012 mandatory?
Yes, the limit values for existing enterprises and the access values for new enterprises are mandatory. Companies must ensure their unit product energy consumption does not exceed these statutory thresholds.
How is the energy consumption calculated under this standard?
The calculation involves dividing the total energy consumption (converted to standard coal) by the raw coal output. It incorporates specific conversion coefficients for factors like mine gas grade and transportation distance to normalize the results across different mining conditions.
