Title: Study on Influence of Gangue on Reclaimed Soil Properties
Abstract: In order to achieve sustainable development of mining area,the soil in reclamation area of Panyi Coal Mine was taken as research object,selecting soil moisture content,bulk density,pH value,organic carbon,available potassium,available phosphorus and total nitrogen as the seven indicators to evaluate properties of soil reclaimed with gangue backfilling and its fertility levels. The results showed that comparing with the control soil, in the soil in reclamation area of Panyi Coal Mine soil moisture,organic matter,available potassium,available phosphorus,total nitrogen content is lower. But the soil bulk density is bigger,and pH value presents slightly noticeable alkaline. In the soil profile,the contents of the seven indicators have little difference in different layers. In the nutrients in the reclamation soil of Panyi Coal Mine,the organic matter and available phosphorus are relatively lacking,especially organic matter content sorely lacking. After weathering,gangue has some effect of increasing fertility for soil. However,since the gangue is alkaline and has high salt content,easy to cause soil salinization in the contacting layer,which should be paid attention.
