The public standard complies with the regulations,
The scope of danger covered by the standard is not included in the standard, and the ratio of the standard to other standards is not included in the standard. 1 Scope
This standard specifies the safety requirements for underground scrapers. This standard is based on the mathematical performance of the predicted use of loaders. The safety requirements contained in this standard are for all hazards of ground loaders. It is applicable to the hazards generated at various stages of the machine life cycle as contained in 3.11 of GB/T15706.1-1595. This standard is applicable to underground conveyors and underground electric conveyors used in mines (except mines). Reference standards The multiple texts contained in the above standards constitute the provisions of this standard through reference in this standard. When the standard was issued, it was valid: all standards will be revised. All parties using this standard should explore the possibility of using the latest version of the following standards.
