Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

1 Scope

This document provides the general principles of ecological environmental damage and compensation assessment in coal mining areas, assessment preparation, damage confirmation, causal relationship analysis, ecological environmental Provide technical guidance on the quantification of physical and value of environmental damage, ecological environmental compensation assessment, and ecological environmental compensation effect assessment.

This document applies to the entire process of ecological environmental damage and compensation caused by coal mining.

This document is not applicable to the ecological and environmental compensation assessment of coal mining areas where the damage caused by changes in land use status cannot be restored.

3 Terms and definitions

The following terms and definitions apply to this document.

coal mining area

Several coal-bearing areas are divided within the coalfield based on factors such as topography, geology, transportation and production management.

Eco-environment of coal mining area the overall environmental system and ecosystem within the coal mining area, including the atmospheric environment, water environment, soil environment, biodiversity, etc.

Eco-environmental damage of coal mining area the undesirable changes in environmental factors such as air, water, and soil, and biological factors such as plants and animals caused by coal mine construction, coal resource exploration, and mining.

Changes in ecosystem benefits and degradation of ecosystem functions and reduction of services composed of the above factors.

The damage situation, analyze the causal relationship between the damage and the ecological environment, assess the scope and extent of the ecological environment damage caused by the behavior, and determine the ecological environment the process of restoring the ecological environment to the baseline and compensating for the damage during the period, and quantifying the amount of ecological environmental damage.
