T/GRM 056-2022 Technical Specifications for the Detection of Water-Conducting Fracture Zones in Coal Mines
Abstract
Scope: This document specifies the detection methods for water-conducting fracture zones in coal mine goafs and the technical requirements for borehole detection and geophysical exploration. This document is applicable to the detection of the development height of water-conducting fracture zones in coal mines, and can also be used as a reference for the detection of the height of water-conducting fracture zones in other layered ore bodies. Main technical contents: 1. General provisions; 2. Terms and definitions; 3. Detection methods for water-conducting fracture zones; 4. Borehole detection of water-conducting fracture zones; 5. Geophysical exploration of water-conducting fracture zones; 6. Report on the detection of water-conducting fracture zones
