5 由  the strongest,in general the thickness is more than 0．3m,the first area takes second place，tectonic coal development of the second area is relatively weak,tectonic coal development strength and fracture fractal dimension and the plane deformation coefficient presents positive correlation． Select fault density，fault strength and fracture fractal dimension,plane deformation coeffhcient and tectonic coal thickness five evaluation indexes，by using the grey fuzzy comprehensive evaluation method to quantitative evaluate Qian Ying Zi coal mine’S tectonic complexity，make mine tectonic complexity comprehensive zoning maps，elicit that the entire study take relatively simple structure and relatively complex structure as main,simple structure area and complex structure area take up a smaller proportion,show sporadic distribution trend，consistent with the production of exposed，provides geological basis for coal mining engineering design． Figures[57]Tables[21]References[-54] Key words：mine geological structure；tectonic development features；tectonic stress field；fuzzy comprehensive evaluation；tectonic coal；Qian Ying Zi coal mine ClassifiCation number：TD 1 63 III 安徽理T大学硕士学位论文 Content s Abstract????????????????????．????．??????????????．??．II 1 Introduction?????????????????????????????????????．．1 1．1 Basis and background oftitle???????．???????????????．??．．1 1．2 Present situation at home and abroad?????????????????????．1 1．3 Research content and technical route?????????????????????．4 1．4 General survey of works and worldand?．．?．?．．?．??．．．?．??．．??．?．．?．?．．．5 2 Survey ofmine geology．．．．．??．?．．．．?．．?．．．???．．．．．．．．．．?．．?．．．．??．．?．．??．．．．．．．．．?．．7 2．1 111e position and transportation ofmine field?????????????????7 2．2 Survey ofphysical geography．．???．．．?．?．．．．．．．．．??．．．．．?．??．?．???．．．．．?．．7 2．3 Mine geological conditions??????????????????????????．8 2．3．1 Regional geological conditions?????????????????????8 2．
