Scope

GB/T 45979-2025 is the English-translated version of 采煤沉陷区卫星遥感动态监测技术规程.

GB/T 45979-2025 is the Chinese national standard covering watching a coal mining subsidence basin from orbit — the mathematical basis and the satellite data to be prepared and collected, the surface subsidence monitoring by offset-tracking and stacking InSAR and how often it is repeated, the parallel land use monitoring that shows what the sinking ground was being used for, the authenticity check and the quality inspection, and the database, the maps and the report that carry the result. The boundary of a subsidence area is generally drawn at the line where the ground has dropped 10.0 mm. First edition, under the China Coal Industry Association. In force from 1 February 2026. Issued on 1 August 2025, it has been in force since 1 February 2026.
