The impact of deep underground coal mining on earth fissure occurrence

Abstract

Deep underground mining commonly causes land subsidence and mining tremors. The occurrence of Earth fissures induced by deep underground mining operations is a rare phenomenon. The development of Earth fissures is a rapid and unexpected process causing a particular hazard to the developed areas. The presented research focuses on the investigation of Earth fissure propagation in the light of geotechnical and geological condition. The presented approach can be used for establishing most significant risk factors influencing Earth fissure development in the areas induced by deep mining.
