適用範囲

This standard is applicable to the calculation, assessment, and energy consumption control of coal surface mining enterprises. It specifically targets open-pit coal mining operations, including both existing facilities and newly established enterprises. It is mandatory for all manufacturers operating surface coal mines in China. The standard does not apply to underground coal mining operations.

技術要求

The standard establishes mandatory energy consumption limits for coal surface mining, categorized into three tiers: a limit value for existing enterprises, an access value for new enterprises, and an advanced value for energy-saving excellence. Compliance with the limit and access values is strictly enforced. The calculation of these limits involves a comprehensive formula that adjusts the raw energy consumption based on specific operational coefficients. These coefficients account for variables such as mining conditions and processes, stripping ratios, average height differences, average transport distances, and the production capacity of a single mine or pit. The standard also mandates the implementation of robust energy management systems, requiring enterprises to establish accountability systems, maintain statistical records, and equip energy metering devices in accordance with GB 17167.

試験方法

The standard outlines specific statistical and calculation methodologies rather than traditional laboratory testing. It requires the collection of energy consumption data across main production systems and auxiliary systems. The core evaluation involves applying a mathematical formula that incorporates various conversion coefficients (detailed in appendices) to normalize the energy consumption per ton of raw coal produced. Enterprises must conduct regular energy audits, monitor major energy-consuming equipment, and maintain documented files of energy balance and assessment results.

よくある質問

What products are regulated under GB 29445-2012?

GB 29445-2012 regulates the energy consumption per unit product of coal surface mining. It applies to the calculation, assessment, and control of energy consumption for existing and newly established open-pit coal mining enterprises.

Are there any updates from the previous version of GB 29445-2012?

GB 29445-2012 is the foundational standard for this specific energy consumption limit. It was drafted according to the rules given in GB/T 1.1-2009. Engineers should verify if any newer revisions have been published by the Standardization Administration of China (SAC) to ensure current compliance.

How does GB 29445-2012 differ from ISO standards?

GB 29445-2012 is tailored specifically to the Chinese coal mining industry's operational characteristics, incorporating unique conversion coefficients for mining conditions, stripping ratios, and transport distances. It references GB/T 28398-2012 for statistical methods, which may differ from general international ISO energy management standards.

The summary above provides a high-level overview of GB 29445-2012.
