首先根据我国矿区土地复垦工作中存在的不足,通过研究提出“动态土地复垦”的概念,并确定了动态土地复垦方案制定的数据基础——动态矿区数字高程模型。动态矿区数字高程模型应该包含煤矿生产对地表的累积影响结果数据和地表的原始地形信息,开采沉陷预计结果可以提供前者,地面测量可以提供后者,经过数据处理可以按时间间隔生成描述塌陷区的一系列数字高程模型(DEM)(准动态),然后运用DEM的空间分析技术提取塌陷区在不同时间段的土地破坏类型、范围和位置数据,并根据这些数据进行动态土地复垦方案决策数据的提取,经实例验证该方法可行。
First of all, according to the existing problems in land reclamation work in our mining area, we put forward the concept of “dynamic land reclamation” and established the data foundation of dynamic land reclamation plan - the digital model of dynamic mining area. Dynamic mine digital elevation model should include the cumulative impact of coal mine production on the surface of the data and the surface of the original terrain information, mining subsidence prediction results can provide the former, the ground can provide the latter measurement, data processing can be generated by time interval to describe the collapse of the area A series of digital elevation model (DEM) (quasi-dynamic) is then used to extract the type, range and location data of land subsidence in different time periods by using the spatial analysis technology of DEM. According to these data, the dynamic land reclamation plan decision data Extraction, verified by examples that the method is feasible.
