Application of geo-information technology in mining area subsidence analysis

摘要

The exploitation of coal may cause surface subsidence. It can reduce the influence and damage for environment if we predict the shape of subsidence. It is also an important link of sustained development strategy. Combining routine subsidence monitoring technology with geo-information technology and analyzing it, we put forward science evidences for control and administer the ecological environment of mining area. Taking Feicheng mining area as research area authors statistic different time subsidence area using geo-information technology and analyze the dynamic change of it. It provides a rapid and economic method for mining area subsidence monitoring.
