摘　　要：为了提高掘进工作面冲击地压危险性评价的准确性,提出了基于多因素耦合的半定量半实测评价方法,通过考虑掘进工作面冲击危险性的影响因素,以及影响因素在矿井的影响程度、范围,得到掘进工作面冲击危险性评价结论。针对不同冲击类型和程度的危险区,制定了针对性的冲击地压治理方法,并在多个矿井得到成功应用。以临矿集团古城煤矿千米深井强冲击煤层3208掘进工作面为例,阐述评价模型与方法的应用情况,结果表明:评价得到掘进工作面冲击危险区的位置、危险程度,相比传统宏观评价方法更准确合理;提出的有针对性的危险区处理方案有效解除了3208掘进工作面的冲击危险,并且减少卸压的盲目性,提高了解危的效率;基于多因素耦合的半定量半实测评价方法可为具有相似条件的矿井掘进工作面冲击地压防治工作提供技术参考。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.
