Compliance overview
Scope and applicability
This standard applies to various mine site mixed and charged explosive trucks (hereinafter referred to as mixed trucks) used in open-pit and underground mines. This includes on-site mixed emulsion explosive trucks, on-site mixed granular ANFO explosive trucks, and on-site mixed heavy ANFO explosive trucks. It is mandatory for manufacturers and operators of these specific mining vehicles. The standard does not cover general mechanical, electrical, hydraulic, or pneumatic hazards that are already addressed in GB/T 15706.1 and GB/T 15706.2.
Technical requirements
The standard outlines a comprehensive hazard list and specifies safety requirements across several key areas. It mandates that mixed trucks must operate safely within an ambient temperature range of ±40°C and relative humidity up to 90%. Trucks must be designed according to ergonomic principles to reduce operator fatigue and prevent hazards from power interruptions. Critical safety features include the mandatory installation of anti-static grounding devices and the use of anti-static rubber hoses with metal braiding for explosive delivery. Regarding vehicle operation, the standard sets strict stability and dimensional limits in accordance with GB 1589. Trucks must be equipped with vehicle driving recorders and satellite positioning systems. For road travel, specific speed limits are enforced depending on the road type, and operations must cease during severe weather like thunderstorms. The trucks must only transport non-cap-sensitive emulsion matrices, adhering to specific hazardous material storage and transportation classifications. The explosive preparation system requires automatic alarm and shutdown mechanisms for conditions like missing raw material phases, empty pump operation, over-temperature, or over-pressure. The system must feature both manual and automatic controls, with continuous monitoring of the explosive density and the charging process. Furthermore, the electrical control system must comply with GB 5226.1, achieve an IP54 enclosure protection rating per GB 4208, and include emergency stop devices that do not trigger secondary hazards. Fire prevention and workplace safety are heavily emphasized. Trucks must be equipped with appropriately fixed fire extinguishers and exhaust spark arresters complying with GB 13365. Open flames are strictly prohibited in the operating area during explosive mixing. The standard also details requirements for hydraulic systems, pneumatic cleaning systems, and clear usage information, including product nameplates and comprehensive instruction manuals.
Testing methods
While the standard primarily focuses on design and operational safety requirements, compliance is verified through adherence to referenced testing and evaluation protocols. Key evaluations include verifying the electrical enclosure protection rating (IP54) according to GB 4208, assessing hydraulic system safety per GB/T 3766, and ensuring the acoustic warning devices meet the audibility requirements of GB/T 1251.1. Manufacturers must ensure all safety devices, such as automatic shutdown systems for over-temperature/over-pressure, are functionally validated.
FAQs
What products are regulated under GB 25527-2010?
GB 25527-2010 regulates mine site mixed and charged explosive trucks used in open-pit and underground mines, including trucks for emulsion, granular ANFO, and heavy ANFO explosives.
Is GB 25527-2010 a mandatory standard?
Yes, except for Chapter 3 (Hazard List) which is recommended, all other chapters of GB 25527-2010 are mandatory. Manufacturers must comply with these safety requirements to sell and operate these vehicles in China.
What are the key electrical safety requirements for the explosive trucks?
