Abstract: The protection and integrated management of mine environments can be carried out effectively, and sustainable development in mining can be promoted if the area of the influence of mine environmentss can be accurately delimited.Based on the theory related to geology and through depened study in the site of Yiyuan coal mine, mining area stratum lithology, geological structure and other geological environments conditions are reviewed, current situation and existing mining environmentsal problems are analysed in detail..Based on the safe depth of mining, displacement angle, boundary and the theory of groundwater balance in the process of mining activities, several different types of area of influence of mine environments that were induced by mining activities have been analyzed systematically, geological hazard area was determined by displacement angle.The area of influence by mining was determined by boundary, area of influence by drainage was determined by big well method of cone of exhaustion.According to the types of geological environmental problems and the coupled degree of influence, the coupled area of influence of mine environments was divided into three areas: serious, more serious and less serious, and the quantitative indicators were given.
