Farmland Damage and Treatment Status in Coal Mining Subsidence Area with High Phreatic Water Level

Abstract:

It is a typical and representative problem which coal mining has been causing serious damage in the Eastern Plains of China with high phreatic water level. Based on GIS technology, we analyzed the characters of cropland and coal resources, the results showed that the area of the overlapped areas of cropland and coal resources was 1.28 × 10⁵km², which accounted for 38.22% of the total arable land of the study area. Based on investigation and statistics, we investigated and forecast the farmland damage and analyzed the comprehensive treatment status in the typical region, the results showed that coal mining led to farmland subsided depth and perennial water, the recovery rate of cultivated land was between 50% and 70% in the treated area and more lower in the untreated area, the trend of arable land area continued to reduce would be hard to contain, the local governments faced unprecedented pressure on cultivated land protection.
