基于遥感技术对兖州煤田采煤塌陷地现状调查
|
摘要
为了解兖州煤田采煤塌陷地、积水区范围及面积、煤矸石山位置及占压土地面积等,采用遥感技术以CBERS遥感数据,遵循《1∶5万区域环境地质勘查遥感技术规程》(DZ/T0190-1997),地面分辨率20m,图像成图比例尺1∶5万,经计算机合成的假彩色片和增强处理,根据片种和工作需要,采用直判法、对比法、邻比延伸法、证据汇聚法、逻辑推理法、水系分析法、影纹分类法和综合景观分析法等多种方法配合使用,采用计算机数字图像处理、遥感资料综合处理、室内解译与野外验证互相结合。提高了野外调查的质量和针对性,缩短调查周期。
In order to know collapse areas, the scope and square water-logged areas, location of coal gangue, and the square of occupied land in Yanzhou coal mine, by using CBERS remote sensing data, abiding by "regional environment geology exploration remote sensing technology procedures with the scale of 1:50000"(DZ/T0190-1997),with the requirement of ground resolution 20m and final image with the scale of 1:50000, depending on the working requirements, by using direct discrimination, comparison, extension, evidence gathering, logical deduction, drainage analysis, shadow lines classification and landscape comprehensive analysis, using computer digital image processing, remote sensing data processing, and the combination of indoor interpretation and field validation, the quality of field investigation has been improved, and the cycle of investigation has been shortened as well.
