Core Terminology System of Coal Geology
Classification of coal genesis
Humic coal (2.29) is contrasted with Sapropeltic coal (2.30):
- Humic coal: formed by higher plants in peat bogs through gelation, accounting for more than 90% of my country's coal resources
- Sapropeltic coal: formed by lower plants in lake environments through sapropelization, such as algae coal
Technical indicators of coal seam exploration
| Classification of coal seam stability | Thickness change rate | Minability |
|---|---|---|
| Stable coal seams (5.30) | <20% | Fully mineable |
| Relatively stable coal seams (5.31) | 20-50% | Mostly mineable |
| Unstable coal seams (5.32) | >50% | Partially mineable |
New resource/reserve classification system
The 2008 version introduced the United Nations UNFC classification framework and established a three-level system:
- Reserves (6.19): Economically mineable part, including mineable reserves (111) and proven pre-mineable reserves (121)
- Basic reserves (6.20): meet industrial index requirements, such as controlling economic basic reserves (122b)
- Resources (6.21): including inherent economic resources (331-333) and predicted resources (334?)
Implementation suggestions
Special requirements for coalbed methane exploration
Newly added Adsorption isotherm curve (7.14) testing requirements:
- Langemuir volume (VL) and pressure (PL) must be determined
- The critical desorption pressure should reach more than 40% of the reservoir pressure
