Abstract:Abstract: Integration management model for mining includes five steps: stripping, mining, transportation, dump piled up and reclamation. There is immediate and indirect impact on ecosystem from land destruction in mining area. In this paper, a comprehensive assessment model was used to explore the ecological risk value as exemplified by Antaibao open-pit mine of Shanxi province, China. In recent years, most researches are done for ecological risk assessment from the perspective of landscape ecology and the risk of heavy metal contamination. However less attention has been paid to the comprehensive risk assessment in the coal mining area. The mining area ecological system is easy to be disturbed and more complicated than general regions. The establishment of the ecological risk assessment model of land destruction ecological risk value (ERV) mainly includes two aspects: the effect of Antaibao opencast coal mining exploitation and ecological sensitivity of mining area. The larger environment influence of mining area by mining exploitation, the higher risk the ecological system would have. On the other hand, if the ecological system is more sensitive and fragile, the resistance and the ability to recover are lower. In this paper, we divided the study area into 30 m by 30 m grid unit and evaluated each unit to realize the mapping and classification of eco-risk in mining area. First, mining area ecological risks were identified from two aspects, production process of the mining and land destruction type in mine area. A typical open-pit mine ecological risk causal chain in Loess Plateau Region was constructed. Second, ecological index based on remote sensing and land-use type was developed specially for assessing mining area ecological sensitivity. The index was combined with six indicators which were adjusted by the important ecological indicators frequently used in assessing regional ecology and special ecological situation in mining area. Third, the data of the cumulative effect evaluation of land destruction and GIS-based ecological sensitivity evaluation were applied to quantify the comprehensive value of ecological risk. The results showed that un-reclaimed dump was the highest risk area (32.91% of the total area). Due to the reclamation measures and management for many years, reclaimed dump and industrial site were stable (9.66% of the total area). However, the unmanaged dump process and weak supervision caused soil and vegetation degradation. Therefore, some part of reclaimed dump showed a higher risk (26.46% of the total area). The open pit was the lowest risk area (30.97% of the total area). It was helpful to take the corresponding management level and constructing the preventive measures according to the risk value of different area. The occurrence of the mining area ecological risk was a dynamic process. The potential risk of disclosure may delay. This meant that we should take preventive in the process of production. If the risk occurred, it would take great harm in the mining area fragile ecosystems. Ecological risk assessment in mining area needed to be from the original single risk evaluation to the multi-level risk assessment so that we can fully embody the application value of the risk assessment as an important means mining area compound ecosystem management. This study made ecological risk assessment on the land destruction of mining area in order to realize ecological quantification and spatial visualization of the open mining and put forward the risk prevention measures for the subsequent production management.
