Classification and classification of groundwater resources reserves
1 Scope
This standard specifies the classification and classification of groundwater resources reserves.
This standard is applicable to groundwater resources planning, investigation and evaluation, development and utilization and protection management, groundwater resources survey and evaluation design and permission
Mining volume calculation, results acceptance, report writing, review and approval can also be used as a reference.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Groundwaterresources
Buried below the surface, the water volume, water quality, water temperature, etc. can be used at present or in the future. Gravity water with practical or potential economic significance.
Note. Including groundwater and mineral water in water and gas minerals, geothermal water in energy minerals, natural brine in mineral salt (referred to as underground brine in this standard), etc.
3.2
Identified resources
Groundwater resources that have been discovered through exploration or mining verification.
Note. According to its accuracy, it can be divided into three levels. verified, proven, and controlled.
3.3
Potential resources undiscoveredresources
Unverified groundwater resources predicted based on geological and geophysical data.
Note. According to its accuracy, it can be divided into two levels. inferred and predicted.
3.4
Reserves of groundwater resources
Under the current economic and technological environmental conditions, the quantity of groundwater resources in the aquifer has been found to a certain extent through survey work.
Note. Including storage volume, replenishment volume and mineable volume.
3.4.1
Storage
The amount of water stored below the fluctuation zone of the water level in the aquifer or aquifer system.
Note. Divided into volume storage and elastic storage.
3.4.2
Recharge
Under natural or mining conditions, the amount of water entering the aquifer in various ways per unit time.
3.4.3
Workable reserves; exploitable reserves
The quantity that can be mined from the aquifer through exploration or mining verification.
Note 1.The recoverable volume is part of the groundwater storage and recharge volume.
Note 2.The recoverable volume is also called recoverable reserves.
3.4.4
Allowablewithdrawal
The quantity that can be mined from the aquifer under the current economic, technological, and environmental permits through exploration or mining verification.
Note. The allowable mining volume is part of the mining volume.
3.5
Groundwater resources exploration explorationofgroundwaterresources
Taking specific groundwater resources as the object of investigation, through comprehensive surveys on the basis of geological survey, geophysical prospecting, drilling, testing and long-term dynamic observations.
Combined research and calculations, and put forward the allowable mining volume and mining plan suggestions for different exploration precisions.
3.6
Regional groundwater resources evaluation estimationofregionalgroundwaterresources
Taking a hydrogeological unit or administrative unit as a unit, on the basis of fully collecting and analyzing predecessor data, through the investigation of the mining volume
And the analysis of dynamic observation data, as well as the calculation of storage and replenishment, propose different levels of allowable mining and recommended mining in this area
Program.
4 General
4.1 The classification and grading of groundwater resources are designed to unify and standardize various types of groundwater resources with the same or similar attributes.
Check and evaluate the principles to be followed when submitting the allowable mining volume.
4.2 Groundwater in water, gas and minerals is often used as a water source for urban, industrial and agricultural production and domestic water supply, and is called general groundwater. Water and gas minerals
Mineral water, geothermal water in energy minerals, natural brine in mineral salt (referred to as underground brine in this standard) are called special groundwater. Groundwater
See Appendix A for classes.
4.3 According to the accuracy of hydrogeological work, the exploration of groundwater resources is divided into three stages. general survey, detailed investigation, and exploration.
Ming's three-level accuracy, the geological survey and mining phase correspond to the predicted and verified two-level accuracy. According to the actual situation, the stage can be simplified and combined
In addition, the allowable mining volume submitted after the simplification and merger should meet its high-level accuracy requirements.
4.4 The reserves of groundwater resources are classified according to the attributes of water volume, and the allowable mining volume is classified according to the working accuracy. Calculation of storage and replenishment
The purpose is to demonstrate the reliability of the allowable mining volume, and the storage volume and replenishment volume are not classified.
4.5 The determination of the allowable mining volume should be treated differently. The general groundwater allowable extraction volume submitted by the survey and evaluation of groundwater for water supply is based on
Determined by GB 50027; the allowable mining volume submitted for exploration and evaluation of geothermal water, mineral water, and underground brine shall be in accordance with GB/T 11615,
GB/T 13727, DZ/T 0212 (all parts) confirmed.
4.6 Surface brine, according to its mobility characteristics, can be classified with reference to this standard for its allowable mining volume.
5 Classification
5.1 Classification
The reserves of groundwater resources are divided into three categories. storage, replenishment and exploitable capacity. The recoverable volume is part of the replenishment volume and storage volume. allow
Permissible mining volume is part of the mining volume.
5.2 Classification
The storage volume and supply volume are not classified. The allowable mining volume is divided into five levels. verified, proven, controlled, inferred, and predicted.
Should be A, B, C, D, E five-level accuracy. See Appendix B for the credibility of each level of accuracy.
5.3 Classification table
The reserves of groundwater resources are divided into three categories and five levels (see Table 1).
5.4 Allowable mining volume levels at different stages
There are five levels of allowable mining volume submitted at different stages of groundwater resources survey and evaluation.
a) In the mining stage, the permitted mining volume (level A) is mainly submitted for verification;
b) During the exploration stage, the proven (level B) allowable mining volume is mainly submitted;
c) In the detailed investigation stage, the permitted mining volume is mainly submitted for control (Level C);
d) In the census stage, the inferred (level D) allowable mining volume is mainly submitted;
e) During the geological survey stage, the predicted (level E) allowable mining volume can be submitted.
For regional groundwater resources evaluation, the allowable mining volume of the corresponding level can be submitted according to the degree of groundwater exploration in different blocks.
