| 摘 要： | 利用CASS从煤矿已有数字地形图上提取矿区地表塌陷前的高程数据,并在CASS中进行插值加密,利用开采沉陷预计程序对插值加密后的高程数据进行下沉修正计算,生成了塌陷后的矿区地表高程数据,利用该数据在CASS中通过简单的数据处理实现了煤矿塌陷区数字地形图的预计更新。该方法对煤矿生产单位的测绘工作以及开采沉陷防灾减灾工程的设计具有实际意义。

| Abstract: | The elevation data can be extracted from the mine digital topographic map based on CASS before the mine surface begins to subside,and the elevation data can also be interpolated based on CASS.Using the subsidence forecasting procedure to modify the interpolated elevation data of mine area can produce the mining subsidence elevation data file.Updating digital topographic map in mine subsidence area can be realized through the simply data processing based on CASS.It has the significance to the surveying and m... |
