鄂尔多斯采煤损毁土地预测与复垦模式分析

鄂尔多斯地区作为我国的主要储煤区,由于煤炭开采导致的土地损毁问题日趋严峻,探索适宜该区自然条件特点的采煤沉陷损毁规律与土地复垦模式,对于该区土地资源可持续发展具有重要的现实意义。在对生产工艺、土地利用现状分析的基础上,采用MSPS软件对项目区采煤沉陷土地进行损毁范围及程度分析,进而结合损毁预测结果制定复垦措施:对耕地区因地制宜进行梯田整地、灌溉、排水设施建设,林、草地区在尽量减少地表扰动的前提下适时补植,并加强管护。

Study on the Land Destruction Forecast and Reclamation Modes in Ordos Region

The coal resources are abundant in Ordos region.The land destruction is becoming more and more serious as the coal mining.The landsubsidence law and reclamation modes adapted to the natural characteristics of Ordosregion were explored in the paper,which had great significance for sustainable development of land resources.Based on analysis of production process and land use condition,the land destruction scope and degree of the coal-mining region was analyzed by software of MSPS to confirm reclamation measures with the forecast results.The measures included that construct terrace site,irrigation and drainage facilities properly,replant timely onthe premise ofminimize the surfacedisturbance at forest andgrass areaand reinforce management.
