Surface subsidence due to underground mining

2015-6-1  Indonesia produced 400 Mt of saleable coal in 2013 with rapid increase in production by almost 99% of surface mining year by year as shown in Fig. 1 (BP, 2013, Indonesia Coal Mining Association, 2014).On the other hand, the rapid increase in production has brought strong concerns on sustainable supply of coal with current quality level in future, due to deepening mining location with

A rapid method for quantifying landscape-scale

Quantifying landscape-scale vegetation disturbances by surface coal mining () is crucial for assessing and mitigating its negative impacts on the environment. Methods for detecting such disturbances in woody ecosystems exist, but these methods do not work well for deserts and grasslands in arid and semiarid regions because of their sensitive responses to precipitation variations.
