中文摘要:冲击地压作为煤矿生产现场的典型动力灾害,给煤矿的安全生产带来极大威胁。本文提出一种新的权重融合方案,将层次分析法与CRITIC赋权法相结合,实现主观赋权和客观赋权的结合,减小融合后的权重值与评价指标实际权重值的偏差。根据调研煤矿现场实际及相关文献,建立包括煤岩物理力学因素、地质因素等4个一级指标,单轴抗压强度、自重应力等23个二级指标的融合权重-云模型煤矿冲击地压危险性评价模型。通过兖矿集团某煤矿的现场实践,该模型评价结果与煤矿现场冲击地压防治实践得出的结果相适应,融合权重-云模型煤矿冲击地压危险性评价模型具有较好的适用性。

Study on Risk Assessment of Rockburst in Coal Mine Based on Fusion Weighting-Cloud Model
Abstract:As a typical dynamic disaster in coal mine production site, rock burst poses a great threat to the safety of coal mine production. This paper proposes a new weight fusion scheme, which combines analytic hierarchy process with RITIC weighting method, realizes the combination of subjective weighting and objective weighting, reduces the deviation between the weighting value after fusion and the actual weighting value of evaluation index. According to the investigation of the actual situation of the coal mine site and the related literature, the risk assessment model of coal mine rockburst is established, which includes four first-class indexes such as physical and mechanical factors of coal rock and geological factors, and 23 second-class indexes such as uniaxial compressive strength and gravity stress. Through the field practice of a coal mine in Yankuang Group, the evaluation results of the model are consistent with the results of the practice of prevention and control of rock burst in the field of coal mine, and the fusion weight cloud model coal mine rock burst risk evaluation model has?the?advantages?of?adaptability.
