この概要は現在英語のみで提供しています。

適用範囲

This standard specifies the safety requirements for the design, manufacturing, installation, use, and maintenance of belt conveyors used in coal mines. It applies to underground coal mine belt conveyors and those used in explosive environments such as open-pit coal mines and coal preparation plants. It does not apply to steel wire rope traction belt conveyors. The standard is modified based on ISO 1819:1977.

技術要求

The standard mandates that all conveyor designs ensure stability and strength under normal working conditions. It requires the use of flame-retardant conveyor belts and specifies that non-metallic components must meet anti-static and flame-retardant standards. Manufacturers must ensure that the maximum surface temperature of any component does not exceed specified limits to prevent ignition. Electrical equipment must comply with explosion-proof requirements outlined in GB 3836.1 to 3836.4. Conveyors must be equipped with comprehensive mechanical and electrical safety protection devices, including sensors for slippage, smoke, coal accumulation, and temperature. For conveyors exceeding 100 meters in length, emergency stop devices must be installed along the pedestrian walkway. Inclined conveyors prone to overspeed or reversal require reliable braking or backstop devices with specific deceleration and torque parameters. During installation, the standard dictates specific requirements for platforms, walkways, and ladders to ensure personnel safety, including minimum widths and anti-slip measures. Firefighting equipment must be installed at the head, tail, and at regular intervals along the tunnel. Strict operational protocols must be followed, prohibiting personnel from riding on non-passenger conveyors and requiring certified operators. Regular maintenance and inspection of moving parts are mandatory.

試験方法

The standard references several specialized testing methods to verify compliance. Flame retardancy and anti-static properties of conveyor belts and polymer components are evaluated according to MT 113, MT 450, and MT 668. The performance of safety protection devices is assessed based on MT 872. Additionally, braking systems undergo rigorous testing to ensure braking acceleration and torque meet the specified safety margins.
