Study on Soil Moisture Surrounding Coal Mining Subsidence Crack in Semi-Arid Region

Abstract:

To provide theoretical basis for vegetation construction surrounding coal mining subsidence crack in semi-arid region, the focus of studying is on the soil moisture surroundings, the coal mining crack in different widths and soil moisture on different directions of a single crack. The result shows that the greater crack width is, the greater influence on soil moisture, the greater influence on deep soil moisture are. The standard deviations of soil moisture at each distance are crack width 0-20cm< width 20-40cm < width 40-60cm < width>60cm. Soil moisture along the crack direction has no obvious distribution regularity, on the vertical crack strike, and within a certain distance, with the increase of distance between crack, the tendency of soil moisture content is increased.
