Rapid development of remote sensing technology has become an important means of geological hazards monitoring. Domestic high- resolution satellite data such as TH-1, ZY-3, GF1/2 and BJ-2, because of its high quality and low price, are more and more widely used in the field of geology. However, there are still some problems in data processing and the research on domestic satellite data in coal mining geological hazards monitoring is not much. So it needs further research and application. This paper aims to establish a set of technology scheme for dynamic monitoring and analysis of geological hazards in coal mining collapse area based on domestic high-resolution satellite. We selected the Xinjiang Uygur Autonomous Region Midong District of Urumqi where geological disasters are more serious as the study area, compared and analyzed the domestic high-resolution satellite images based on the TH-1 (2014), GF-1 (2015), BJ-2 (2016). This paper identified dynamic change of geologic hazard, set up the symbol of interpretation, evaluated and explored the practicability of land disaster investigation and dynamic monitoring with domestic high-resolution satellite. Based on the dynamic monitoring with domestic high-resolution satellite data from 2014 to 2016, we found that the geological disasters such as ground collapse and ground cracks are increasing. We suggest that it should be planned first, and exploitation should be scientific. It is necessary to strengthen the restoration of governance.
