Annual monitoring and analysis of newly damaged land in mine development in Shanxi province

Timely and accurate monitoring of the change of mine development land occupation is the main task of mine geological environment monitoring.This paper uses high spatial resolution remote sensing data as the main data source, using human-computer interaction interpretation methods extract the annual mine development newly damaged land status in Shanxi province from 2018 to 2019, and the scale, spatial differentiation and expansion mode of newly damaged land in mine development are analyzed.The results show that solid waste and mine stopes are mainly the types of newly land damaged by mine development in Shanxi province from 2018 to 2019.The mine development process involves 51 kinds of minerals in Shanxi province from 2018 to 2019, and the mining activities of coal mines are the main reason for the expansion of newly damaged land; the scale and quantity of newly damaged land in many cities show high-value clusters in the hot spot analysis chart, including Xinzhou city, Yangquan city, and Lyuliang city.The south and north of Shanxi province belong to the expansion cold spot area.The sprawl mode of newly damaged land in Shanxi province from 2018 to 2019 is mainly edge sprawl, followed by exclave sprawl, and the number and scale of infill sprawl are the least.
