Scope
NB/T 11138-2023 is the English-translated version of 矿用主井装卸载控制装置.
NB/T 11138-2023 is the Chinese energy industry standard covering the units that control skip loading and unloading on mine main shafts, devices built on sensing, programmable logic controller (PLC) and computer technology.
Such a device gathers coal level, pressure and position signals, processes them in a PLC and drives the actuators, while an operating unit exchanges signals with flameproof and intrinsically safe control boxes and displays the status of the loading and unloading equipment.
The standard sets out the product model, technical requirements, test methods, inspection rules, and marking, packaging, transport and storage, with an informative appendix describing the main function test process.
It applies to shaft transport workplaces in coal and non-coal mines. Issued on 6 February 2023, it has applied since 6 August 2023.
