基于盲数理论改进未确知测度的冲击地压评价模型应用研究

Application of Blind Number Theory to Improve Unascertained Measure Rock Burst Evaluation Model

冲击地压的影响因素较多,冲击地压评价过程中含有很多不确定信息,常规的冲击地压评价方法未能将这些不确定信息统筹考虑,造成评价结果失真;基于盲数理论,统筹考虑冲击倾向性、地质因素、开采技术因素、安全管理因素构建未确知测度冲击地压评价模型,并应用于隰东煤业有限公司冲击地压危险评价。工程实践结果表明,基于盲数理论的未确知测度冲击地压评价模型精度较高,较好地适用于现场实践。

There are many factors affecting rock burst,and there is a lot of uncertain information in the process of rock burst evaluation.Conventional rock burst evaluation methods fail to consider the uncertain information as a whole,resulting in the distortion of evaluation results.Based on the blind number theory,this paper considers the impact tendency,geological factors and mining technology in an innovative way.The factors and safety management factors construct the unascertained measure rock burst evaluation model which is applied to the risk assessment of rock burst in Xidong Coal Industry.The engineering practice results show that the unascertained measure rock burst evaluation model based on blind number theory has high accuracy and is better suitable for field practice.
