Coal is an important resource that has supported China’s economic development. This situation is expected to continue in the immediate future. However, coal mining has also led to serious environmental disasters in some mining areas. Henan Province is one of the 14 largescale coal bases that are planned by the Chinese state. It Distribution and environmental impact of coalmining ,mining district and in the central part of the USCB (Fig. 2). There are 380 coalmining waste dumps, including 76 active dumps covering 2166 ha in the Katowice district (State Inspectorate of the Environment Protection 1995). Up to the late seventies, the selfignition of coalmining waste dumps was a primary concern, and potential polluReview of the recent advances in the prevention, ,Under the longterm interaction between coalbearing strata and groundwater, particularly in highsulfur coal mining areas with large amounts of hematite and pyrite exposed, acid mine drainage (AMD) is easily formed, as shown in Fig. 1 [3], [4].Acid mine water contains sulfuric acid, Fe 2+, Fe 3+, Mn 2+, etc., may also be enriched with some traces of toxic
Rehabilitation of Mine Wastes INTRODUCTION Humanity faces many environmental challenges in the 21st century. The issues of land degradation, resource deple wastes and especially barren waste rocks from coal and metal mining are as building and construction materials. These wastes are used as fill for subsided land or as aggregates The Challenges of Reusing Mining and MineralProcessing ,The origin of mining and mineralprocessing wastes is closely related to the formation of the target resource or minerals. For example, many coal deposits exist in subsided regions resulting from mountain formation; hence, the overlays of coal resources are generally not very thick and consist of relatively inactive sedimentary rocks.Technical Paper,coal washery wastes in Australia.

Effective Methane Drainage and Use in Coal Mines . Largescale coal production will continue for many years to come. Coal production, transportation, storage and use account for approximately 40% of global greenhouse gas emissions.

The alkaline industrial wastes are usually applied on mine wastes as top covers designed to limit acid generation by restricting water and oxygen infiltration into the mine waste piles, neutralize acid, and immobilize metal (loid)s by precipitation (Duchesne and Doye, 2005; Germain et al., 2003; Jia et al., 2014; Mäkitalo et al., ; PeppasImpact of the Coal Mining on the Spatial Distribution of ,Coal mining areas are prone to hazardous element contamination because of mining activities and the resulting wastes, mainly including Cr, Ni, Cu, Zn, Cd and Pb.
