Study On Hig-Productivity & Efficiency Coal Mine And Ecological Environment

Since 90s, many hig-productivity & efficiency coal mine have been established with the development of science and technology and with the improving of mechanization. Establishing of hig-productivity & efficiency coal mine do contribute to developing economy. However, developing of hig-productivity & efficiency coal mine inevitably bring negative effect, and ecological environment is affected badly . So, how to protect ecological environment become a important question for discussion about developing of hig-productivity & efficiency coal mine. The paper try to probe into questions about the developing of hig-productivity & efficiency coal mine and ecological environment using related results of study in or out my country for reference, the author wish sincerely the paper make some effects to the developing of hig-productivity & efficiency coal mine.The paper include six parts.Part one: summarize of hig_productivity & efficiency coalmine.introduce the conception, the characteristic and the developing of hig-productivity & efficiency coal mine.Part two: basic theory of ecological environment.The part analyse some theory of ecological environment: one is the meaning, function and characteristic of ecological environment, and another is the theory about value of ecological environment and estimating of value of ecological environment.Part three: hig_productivity & efficiency coal mine and ecological environment.Analyse the relation between hig-productivity & efficiency coal mine and ecological environment, discuss the effects of hig-productivity & efficiency coal mine on ecological environment and the reason for the effects.Part four:The techniques of protecting ecological environment in hig-productivity & efficiency coal mine.Probe into the techniques about exploiting and constructing of hig-productivity & efficiency coal mine and processing of coal, the techniques are mostly clean mining technique and clean coal technology ,The part is important one of the paper.Part five: The countermeasures of protecting ecological environment in hig-productivity & efficiency coal mine.introduce some countermeasures of ecological environment protecting in hig-productivity & efficiency coal mine.Part six: Economy evaluating of environment protecting.Introduce the method of input-output, and try to use the method of input-output toanalyse waste of hig-productivity & efficiency coal mine, at last, evaluate environment expenses of hig-productivity & efficiency coal mine.
