Coalfield Tectonic Framework And Tectonic Coal-controlling Of Hebei Province

The paper mainly discusses the coalfield structures of Hebei province with fully application of the theory of geodynamic, coalfield geology and coal resources exploration. Making the tectonic coal-controlling as the core, the control effect of regional tectonic framework and evolution to the coalfield structures is deeply discussed and the division scheme of coalfield tectonic units of Hebei province is established on the basis of coalfield tectonic characteristics. Using the field geological and production mine investigation data and applying various of technical means and test analysis methods, the coalfield tectonic characteristics and genetic evolution mechanism of each coal-occurrence tectonic belt are discussed in detail and the genetic and characteristic differences of coal measures deformation under different dynamic backgrounds are ascertained, and the classification system of coal-controlling structural styles of Hebei province is preliminarily established. Then based on the comprehensive analysis, the basic coal-occurrence laws are discussed. In the end, in consideration of the geological and exploration achievements, the block prediction method is used to newly predict and evaluate the coal resources potential of each coal-occurrence tectonic belt, providing basis for the coal resource exploration.
