Abstract
AbstractUnder the background of the ecological civilization era, rapidly obtaining coal mining information, timely assessing the ecological environmental impacts, and drafting different management and protection measures in advance to enhance the capacity of green mine construction have become the urgent technical problems to be solved at present. Simulating and analyzing mining subsidence is the foundation for a land reclamation plan. The Cellular Automata (CA) model provides a new tool for simulating the evolution of mining subsidence. This paper takes a mine in East China as a research area, analyses the methods and measures for developing a model of mining subsidence based on the theories of CA and mining technology, then discusses the results of simulation from different aspects. Through comparative analysis, it can be found that the predicted result is well consonant with the observation data. The CA model can simulate complex systems. The system of mining subsidence evolution CA is developed with the support of ArcGIS and Python, which can help to realize data management, visualization, and spatial analysis. The dynamic evolution of subsidence provides a basis for constructing a reclamation program. The research results show that the research methods and techniques adopted in this paper are feasible for the dynamic mining subsidence, and the work will continue to do in the future to help the construction of ecological civilization in mining areas.

Summary
Abstract: Under the background of the ecological civilization era, rapidly obtaining coal mining information, timely assessing the ecological environmental impacts, and drafting different management and protection measures in advance to enhance the capacity of green mine construction have become the urgent technical problems to be solved at present. The main modes of mining reclamation are not performed until subsidence entirely ceased This could potentially take three or more years before reclamation processed, resulting in an extended period without the use of the land and extended damage to the surface. Mining subsidence dynamics prediction can show the evolution process of surface subsidence and fully reflect the damage of the ecological environment These aspects will dictate which methods need to be implemented during the reclamation process. Some studies have been conducted in on CA [8,9,10], dynamic simulation for mining subsidence is a complex system problem, the results are largely affected by the model choice and setting [11,12,13], and different conditions need different methods. The work can promote the ecological civilization in mining areas and has a wide application prospect in the field of coal mining and land reclamation
