New developments in influential area of longwall excavation
The Angle of Draw (in Germany referred to as Limit Angle) plays a significant role in the field of mining subsidence engineering.This applies both for the assessment of the affected area by underground mining activities as well as applied methods for the prediction of ground movements.Recent observations using remote sensing show that ground movements outside the affected area defined by the angle of draw have been detected in German hard coal mining.Since the affected area by underground mining activities also plays an essential role regarding claims of landowners with damages on their houses and infrastructures possible solutions for limiting the size of the affected area will be presented in this paper.Ground movements which exceed the affected area of an underground coal mine defined by the angle of draw will be shown in an exemplary manner.According to present knowledge it is expected that ground movements outside the affected area will not cause damage of major significance.This paper outlines the consequences for all affected parties regarding the ground movements due to underground coal mining which extended the extent of the area defined by the currently assumed angle of draw.This will be visualized in a case study.
