摘要:
煤矿开采引起的地面塌陷、地裂缝等地质灾害日益严重,查清矿区地质灾害规模、分布和影响范围,掌握变化趋势,对建设绿色矿山至关重要.应用资源一号02C(ZY1-02C),高分一号(GF-1)和高分二号(GF-2)卫星高空间分辨率影像数据,基于已知塌陷区的基本特点,建立遥感影像地物解译标志体系,通过人机交互目视解译,圈定了新疆铁厂沟煤矿区地面塌陷的边界、展布方向和影响面积.研究表明,国产卫星ZY1-02C,GF-1和GF-2数据能够有效保障矿区大、中型地面塌陷遥感精准识别;国产卫星ZY1-02C和GF-1能满足1:5万比例尺制图要求,GF-2卫星遥感数据可以满足1:2.5万比例尺制图要求.作为我国自主发射的国产高分辨率卫星,数据资源丰富,为今后开展矿山地质灾害遥感监测提供重要数据保障.
Abstract:
The problem which has become serious over time is coal mine zone ' s surface collapse and ground crevice. Therefore, making a thorough investigation of the type, size and distribution of geological disasters in the mining area and analyzing the causes, damage degree and development trend of the geological disasters are very important for the green mine construction. With the ZY1-02C and GF-1/2 data as the basis, on the basis of the characteristics of known subsidence area and the establishment of remote sensing imagery interpretation system, and by using the methods of human -computer interactive interpretation, the authors delineated the boundary, the direction and the influence area of the ground collapse area of the Tiechanggou mine in Xinjiang. The analysis shows that the data obtained by domestic high-resolution satellites of ZY1 -02C HR, GF-1 and GF-2 can effectively guarantee the remote sensing precise identification of large and medium-sized ground subsidence in the mining area. The domestic high-resolution satellite ZY1-02C and GF-1 can meet the 1:50000 scale, and the GF-2 satellite remote sensing data can meet the 1:25000 scale. With the home-made satellites of China, the data resources are abundant, which provide important data guarantee for remote sensing monitoring of mine geological disasters in the future.
