QUANTITATIVE FORECAST FOR COMPLICATED DEGREE OF SMALL STRUCTURE IN COAL SEAM IN TONGER MINE FIELD

The unit forecast method is applied to forecast quantitatively the complicated degree of small structure in main coal seam.First,the class texture of the complicated degree of small structure is built by cluster analysis,it is divided into three types and four subtypes.Second,the relational model between the complicated degree of small structure and geological influence factors is built by regression analysis.Finally,the model may be applied to forecast the complicated degree of small structure in unmined units.
