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.

In the process of mining 6# coal seam, the fractal dimension change law of overburden fissures is similar to that of 5# coal mining, but the inflection point of fractal dimension broken line is different from 5# coal mining. The mining of the 5# coal seam has caused most of the overlying rock layers to be destroyed and the formation of fissures.
