地下煤矿资源开采引起的地面沉陷越来越严重,已成为制约矿区环境、社会经济可持续发展的主要地质灾害之一。本文构建了基于3S(RS+GPS+GIS)集成技术的矿区沉陷精确调查技术,重点利用多时相高分辨率光学遥感影像,通过数据处理及信息提取,获取了山东省济宁某煤矿的2003—2011年的地面沉陷位置、分布,统计了沉陷区面积,基于GIS技术分析了煤矿沉陷区的时空演变。试验证明,3S集成技术是进行矿山沉陷调查的最佳技术方法之一,可实现矿山沉陷的大面积、低成本、准确调查。
Ground subsidence caused by the exploitation of underground coal resources has become more and more serious, and it has become one of the major geological disasters that restrict the sustainable development of mine environment and social economy. In this paper, an accurate survey technology of mine subsidence based on 3S (RS + GPS + GIS) integrated technology is established. The multi-temporal high-resolution optical remote sensing images are mainly utilized. Through data processing and information extraction, a coal mine in Jining of Shandong Province was obtained from 2003-2011 The location and distribution of ground subsidence in year and the area of subsidence area were analyzed. Based on the GIS technology, the temporal and spatial evolution of the coal mine subsidence area was analyzed. The test proves that 3S integrated technology is one of the best technical methods for mine subsidence investigation, which can realize large area, low cost and accurate investigation of mine subsidence.
