Based on studies in Lu’an, Pingdingshan , Yanzhou mining areas and so on, such quantitative assessment methods for coal exploitation environment cumulative effects are summarized as Geographic Information System, Earth Observation and Remote Sensing andEnergy Exploration & Exploitation Numerical simulation of,,As a kind of fossil energy resources, coal plays an important role in the development of the world economy. However, the coal exploitation process is often accompanied by the occur-rence of mine gas disasters, such as coal and gas outburst and gas explosion, resulting in a large number of casualties and property losses (Xu et al., 2006, 2017b).Regional Gas Drainage Techniques and Applications in,,depths, particularly in the economically developed eastern regions, where coal exploitation has a long history, the shallow coal resources are nearly exhausted, and many coal mines have to start mining at depths of 800~1500 m. In China the coal resources within 800~2 000 m of overburden is about 3.25 tt, accounting for 63% of the total reserves.
