河南矿山环境恢复治理遥感调查与分析

为了实时、快速地了解河南矿山环境恢复治理现状，利用遥感影像采用室内解译与野外实地验证结合的方法调查了河南省2019年矿山环境恢复治理情况。调查结果表明:露天采场是所有矿山开采占地最多的用地类型。与2018年相比，2019年全省矿山恢复治理面积大幅度增加，2019年矿山恢复治理12 175.57 km2，比2018年增加2 235 km2，其中露天采场恢复治理面积较大，恢复效果较好，而矸石山、排土场等矿山废弃用地需要加快恢复治理力度。根据解译成果统计，仍然有部分矿山未恢复治理，另外有个别矿山存在越界开采、无序开采、随意乱挖等现象，这些违法开采矿山对环境的影响较大。调查成果可为河南省矿山环境恢复治理监管等工作提供参考。 

Remote Sensing Investigation and Analysis of Mine Environmental Restoration in Henan

In order to understand the status quo of mine environmental restoration and governance in Henan Province in real time and quickly, the remote sensing images were used to investigate the status of mine environmental restoration and governance in Henan Province in 2019 by combining indoor interpretation with field verification.The results show that the open-pit stope occupies the most land in all the mines.Compared with 2018, in 2019, the area of mine restoration and treatment in the province increased significantly. In 2019, the area of mine restoration and treatment was 12, 175.57 hectares, an increase of 2, 235 hectare compared with 2018. Among them, the area of open-pit stope restoration and treatment was large and the recovery effect was good, while the abandoned land of mine, such as gangue hills and dumps, needed to accelerate the restoration and treatment.According to the statistics of interpretation results, there are still some mines that have not been restored, and there are some individual mines that have cross-border mining, disorderly mining, random digging and other phenomena. These illegal mining mines have a great impact on the environment.The results of the survey can provide reference for the environmental restoration and supervision of mines in Henan.
