Research on the Impact of Ground Crack on Soil Nitrogen in Sandy Area Pit Mining

Abstract:

The ground cracks caused by mine activities lead to soil destruction in sandy area. Most of the previous literatures focus on the soil properties change before and after the large area subsidence, and the research of the ground crack impact on soil are inadequate. This paper takes the soil around the static cracks as the research object, analyzes the impact law of the soil total nitrogen by using the comparative analysis method. The impact law and impact range of the soil total nitrogen by ground crack, and the impact mechanism of the soil porosity and soil particle size, are analyzed. The result show that: within 200cm away from static cracks, the soil total nitrogen content is decreases in the close distance, increases in the middle, and keeps gentle change in the long distance; The effect boundary of the total nitrogen by static cracks is about 100cm, providing information for further study on the soil quality influenced by coal mining in the sandy area.
