<跨度样式=“Font-Family:Arial,Helvetica,Sans-Serif”> <跨度样式=“字体大小:14px”> Opencast煤矿对变化的土地使用和陆地覆盖模式产生了巨大的影响任何煤矿带。这是本研究的主要推动力。已经确定了土地使用实践,如建筑区域,农田,植被,水体,裸陆,矿区等。分析了曼加尔普利私人露天矿业换土土地利用和陆地覆盖的模式。与此同时,借助辅助数据研究了整个Raniganj块。SOI地形图73 m / 2 已被用来显示1967年Raniganj块的地下和Opencast的情况。土地使用和陆地覆盖raniganj的变化block have been analysed for 12 years i.e., from the year 2007 to 2019 using remote sensing techniques. The changes have been detected at 6 year time gap. For that purpose Landsat-5 TM, Landsat-8 OLI/ TIRS satellite images are used. Apart from that, the quantification of spatio-temporal dynamics of land use and land cover patterns are also examined by supervised image classification. The study exposed that extend of the mining area and the bare land area has increased in 2019 compared to 2007. On the contrary, cropland and vegetation cover have decreased significantly during the period under study. To achieve sustainable use of land in the study area, some management procedures have been discussed at the end
