【摘要】：利用2013年第4季度—2015年第4季度高分辨率遥感影像数据,对山东省采煤沉陷灾害进行了连续3 a的动态监测,发现全省采煤塌陷地(坑)面积逐年减少。在对比分析山东省煤矿分布特点、煤炭开采方式及开发历史等工作基础上,建立了采煤沉陷遥感动态监测技术流程。根据所提取的塌陷地(坑)、搬迁的村庄、地质灾害恢复治理等信息,圈定全省特大型沉陷区12个、大型沉陷区8个、中型沉陷区50个、小型沉陷区12个;通过上述信息的近3 a变化情况的分析,确定全省沉陷程度变好区30个、稳定区31个、变重区21个,掌握了沉陷变化趋势。同时,分析了煤矿沉陷灾害发生的影响因素,探讨了治理时机,提出了对策建议。
[Abstract]:Based on the high resolution remote sensing image data from in the fourth quarter of 2013 to in the fourth quarter of 2015, dynamic monitoring of coal mining subsidence in Shandong Province for 3 consecutive years was carried out. It is found that the area of coal mining subsidence (pit) in Shandong province is decreasing year by year. On the basis of comparative analysis of coal mine distribution characteristics, coal mining methods and development history in Shandong Province, The technical process of remote sensing dynamic monitoring of coal mining subsidence is established. According to the extracted information of subsidence land (pit, moving village, geological disaster recovery and management), 12 large subsidence areas, 8 large subsidence areas and 50 medium subsidence areas are delineated in the province. Through the analysis of the variation of the above information in the past 3 years, it is determined that the subsidence degree of the whole province has become better in 30 areas, 31 in the stable areas and 21 in the heavier areas, which have grasped the trend of subsidence change. This paper analyzes on the influencing factors of coal mine subsidence disaster, probes into the control opportunity, and puts forward some countermeasures and suggestions.
