Scope

NB/T 11132-2023 is the English-translated version of 采煤机尘源跟踪喷雾降尘系统通用技术条件.

NB/T 11132-2023 is the Chinese energy industry standard giving the general technical conditions for dust source tracking spray systems fitted to coal shearers.

Such a system uses sensors to follow the position and running state of the shearer and switches on spray devices mounted on the top beams of the supports, so that dust raised by the cutting drums is suppressed automatically and in real time.

The document sets out the model designation and its meaning, performance requirements, test methods and inspection rules, together with marking, packaging, the instruction manual, transport and storage.

Its normative references link the system to flameproof and intrinsically safe equipment, dust suppression nozzles, emulsion pumps and hydraulic hoses used underground. Issued on 6 February 2023, it has applied since 6 August 2023.
