The fracture development of the overlying strata after coal mining is an important guarantee of efficient gas drainage. In order to explore the fracture evolution characteristics close to a mined coal seam group, the −24130 working face in the Pingdingshan No. 10 coal mine was taken as the research background. The FLAC3D numerical simulation software was used to study the migration and ...

Surface/open cast mining and deep underground mining are considered two basic methods for coal extraction globally. The rising trend of coal mining activities has resulted in the accumulation of mining and processing wastes with low carbon levels over the past few decades [6]. Fig. 1 presents different life cycle stages of coal with details of wastes generated at each stage.
