Escopo e aplicabilidade

This standard applies to the management and blasting operations of explosive materials used in seismic exploration. It covers various fields including oil and gas exploration, mineral exploration, hydrogeological and engineering geological research, and urban geological surveys. It is mandatory for all entities conducting seismic blasting operations within China, replacing the previous GB 12950-1991.

Requisitos técnicos

The standard specifies comprehensive safety requirements for the entire lifecycle of explosive items, including procurement, storage, transportation, usage, and destruction. It mandates strict administrative controls, requiring operating units to hold valid blasting permits and establish robust safety management mechanisms. All personnel involved in blasting operations must be certified and equipped with appropriate protective gear. For storage, the standard details requirements for both permanent and temporary warehouses, including strict safety distance calculations between explosive storage facilities, surrounding buildings, and high-voltage power lines. It also defines compatibility rules for storing different types of explosives and detonators to prevent sympathetic detonation. Regarding transportation, it outlines technical requirements for vehicles and vessels, mandating features like GPS tracking, electrostatic discharge belts, and specific warning signs. It sets strict limits on load capacities and defines safety protocols for different transportation modes, including road, waterway, and manual transport. For operational use, the standard provides specific blasting procedures categorized by geographical terrain, such as plains, mountains, loess plateaus, deserts, and water areas. It includes detailed protocols for making explosive bundles, managing detonators, and calculating safe distances for blast sites from external electromagnetic and radio frequency sources.

Métodos de ensaio

The standard outlines evaluation procedures primarily focusing on safety verification rather than laboratory testing. Key methods include measuring safe distances using specific mathematical formulas for blast vibration and shock waves, verifying the electrical resistance of detonators using specialized testing instruments, and conducting safety checks for misfires (blind blasts). It also mandates regular safety inspections of storage facilities and quality sampling of explosive products at a rate of no less than 1%.

Perguntas frequentes

What products and operations are regulated under GB 12950-2025?

GB 12950-2025 applies to the management and blasting operations of explosive materials used in seismic exploration across various fields, including oil and gas exploration, mineral勘查, hydrogeological and engineering geological research, environmental impact assessment, and urban geological surveys.

Are there any significant updates from the previous version of GB 12950?

Compared to the 1991 version, this standard introduces new chapters on the procurement and acceptance of explosive items, their destruction, emergency response and accident handling, and quality safety control. It also updates requirements for temporary warehouse setup, vehicle transport, and divides land blasting operations into specific geographical zones (plains, mountains, loess plateaus, and deserts).

How does GB 12950-2025 differ from general blasting safety standards?

While GB 12950-2025 references general blasting safety standards like GB 6722, it is specifically tailored for seismic exploration. It includes highly specialized operational protocols for geophysical surveying, such as managing shot wires, operating seismic-specific blasting machines, and conducting blasting in diverse survey terrains like deserts and waterways.

The summary above provides a high-level overview of GB 12950-2025.
