3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
cavingzone
The range of rock formations in which the overlying strata fractured and collapsed into the gob caused by coal mining.
[Detailed rules for water prevention and control in coal mines (Notice of the State Coal Mine Safety Supervision Bureau on Printing and Distributing the "Detailed Rules for Water Prevention and Control in Coal Mine", Coal Safety Supervision Investigation [2018] 14
No.) Chapter VIII Supplementary Provisions, Article 137].
3.2
The rock strata within a certain range above the coal seam have collapsed and fractured, resulting in a cracked and water-conducting rock stratum range.
3.3
curved belt saggingzone
The strata above the water-conducting fracture zone create a range of curved subsidence.
3.4
gob gobara
Space that is no longer maintained after coal mining.
3.5
small kiln oldkiln
Small coal mine goaf with long mining history and missing data.
3.6
old empty area goafarea
The general term for goafs, small kilns and abandoned wells.
