GB/T 22206-2008Classification of environmental geology of mine (English PDF)

2.1 Sort

2.1.1

Coal Mining Area based adverse environmental geological phenomena (disasters) spatial location and the environment occurs classification plan.

2.1.2

Coal Mining Area based adverse environmental geological phenomena (hazards) of the causes, triggers division type.

2.1.3

based on specific environmental geological problems caused by different genetic types divided subtypes.

2.1.4

on the basis of bad coal mine environment geological phenomena (disasters) protection, remediation status of the secondary partition type.

2.2 by spatial location and environmental classification plan

2.2.1 Atmospheric Environment Geology (I class)

Coal mining area since the waste gas, waste residue and dust emissions in the atmosphere environment has been polluted to varying degrees, and even cause acid rain, can be classified as large

Gas Environmental Geology.

2.2.2 Ground Environment Geology (II type)

Since the underground mined coal mining area, ground and slope excavation, groundwater dewatering, water inrush, wastewater discharge, resulting in land subsidence in goaf (Subsidence, collapse), the mountain crack, collapse, landslides, mudslides, soil erosion and desertification, collapse, encroachment, soil pollution, mine earthquake

And other adverse geological phenomena (disasters), the ground can be classified as environmental geology class.

2.2.3 Groundwater Environmental Geology (III category)

Coal mine area due to the sparse drainage, ground water, waste emissions, abandoned mines closed, resulting in damage to groundwater balance, seawater intrusion, water

Quality environment pollution and other adverse geological phenomena (disasters), the groundwater can be classified as environmental geology class.

2.3 according to the causes, predisposing factors dividing type

2.3.1 Ground Slag Pile type (type I)

Mine waste includes gangue, waste rock and other industrial waste. Depending on the specific environmental geological problems caused by it can be divided into subtypes.

2.3.1.1

Mine waste piled up, leading to excessive land occupation and destruction (subtypes) of the stacking field original ecosystem.

2.3.1.2

Mine waste contained in acidic, alkaline, toxic, radioactive or heavy metals, land contaminated by runoff from the surrounding surface water bodies,

Waters, which exceed the scope of waste piled up design allows the transition range (2 subtype).

2.3.1.3

Mine waste contained in acidic, alkaline, toxic, radioactive or heavy metals, contamination of groundwater resources infiltration (3 Asia through leaching type).

2.3.1.4

Mine waste contained in acidic, alkaline, toxic, radioactive or heavy metals, dust floating through the atmosphere, atmospheric pollution, its shadow

Sound range than waste stacking design allows the intermediate space (4 subtypes).

2.3.1.5

Coal gangue spontaneous combustion process releases large amounts of harmful gases pollute the atmosphere (subtype 5).

Terrain, weather conditions and the impact of human factors 2.3.1.6 coal mining area of waste piling up due to the venue, the occurrence of collapse, landslides, mudslides and other (6

Subtype).

2.3.2 waste water, waste gas discharge type (II)

Mine waste water, waste gas emissions will directly lead to a number of environmental geological problems, based on their specific issues raised can be divided into subtypes.

2.3.2.1

Coal washing waste water discharge and loss of slime contaminated soil, surface water and groundwater (1 subtype).
