In view of the geologic factors for that impacted on the coal mine production,for example,the rift tectonic,the magnetic intrusive rock and so on grew energetically,it very serious affected on coal mine production,research on the character of rift tectonic structure and the rule of intrusive mass growing was urgently needing solution subject of Daxing filed.Based on combined analysis of Daxin field’s geological record and well survy,the author make a lot of research about development of rift tectonics,range’s regularity and intrusive mass’s special spread regularity,summarize the characteristic of rift tectonics and control action to intrusive mass,provide reference to Daxin field’s excavate production.
