Scope

NB/T 10530-2021 is the English-translated version of 滚筒采煤机节能技术方法.

NB/T 10530-2021 describes technical methods for cutting the energy use of drum shearers on longwall coal faces.

After general requirements, it sets out energy-saving measures that act on the operating parameters of the shearer, on materials and manufacturing, and on structural optimization of the cutting unit and travel unit, and then explains how the results are checked.

Informative appendices give an outline for an energy-saving operation plan and a test data record sheet.

The methods target gear-and-pin haulage shearers and guide both makers and users in applying advanced energy-saving technology, with references to the GB/T 35060 shearer series, MT/T 81 type inspection and variable-frequency speed control devices. Issued on 7 January 2021, it has applied since 1 April 2021.
