Effects of Coal Mining Subsidence on the Changes of Soil Nutrient in Shenfu-Dongsheng Coal Field

Abstract:

Ground surface subsidence will cause enormous impact to ecological environment in Coal Gob. But the study concerning the effect of the surface subsidence on soil nutrients is little. Taking Bulianta (Sandstorm--subsidence Area) and Yujialiang (Loess-subsidence Area) coal mine in Shenfu-Dongsheng coal field as study object, The characteristics of soil nutients in non-collapse area and the effect of collapse on soil nutrients are sdudied systematicly by Field sampling and laboratory analysis.The results showed that: With the increasing of soil depth, total soil nutrient content gradually reduced in both stduy areas, While in Sandstorm-subsidence Area, Total nitrogen and total phosphorus increased with soil depth. The total nitrogen and total phosphorus in Sandstorm-subsidence Area is lower than those in Loess-subsidence Area, but the total K is higher than that in Loess-subsidence Area. In a word, the effect of coal mining subsidence on total soil nutrients in both Areas is on the small side.
