Abstract：In order to improve the accuracy of the evaluation on the mine pressure bump danger of the heading face,a semi-quantitative and semi measurement evaluation method was provided based on the multi factor coupling.With the consideration on the influence factors of the mine pressure bump danger from the mine gateway driving face and the influence degree and scope in the mine by the influence factors,an evaluation conclusion was obtained on the mine pressure bump danger of the heading face.According to the different mine pressure bump type and degree danger areas,the pertinence mine pressure bump control method was set up and was successfully applied to several mines.Based on No.3208 heading face in the strong mine pressure bump seam in the 1 000 m depth Gucheng Mine of Linyi Mining Group as a case,the paper stated the application state of the evaluation model and method.The results showed that the location of mine pressure bump danger area of driving face was obtained from evaluation and danger degree was more accuracy and rational than the conventional macroscopic evaluation method.The control plan to the pertinence danger area provided could effectively eliminate the mine pressure bump danger of No.3208 heading face,could reduce the blindness of the mine pressure releasing and could improve the efficient rate of the danger released.Based on the multi factor coupling,the semi-quantitative and semi measurement evaluation method could provide the technical references to the mine pressure bump prevention and control work of the mine heading face with similar conditions.
