摘要
矿井受到外界环境和内部因素影响,很有可能出现塌方。塌方程度不同,造成的影响也不同。目前研究的矿井塌方风险评估模型整理采集数据能力较差,无法完整性地研究数据,难以实现动态评估,得到的决策方案不够科学。针对上述问题,在传统矿井塌方风险评估模型的基础上,设计了一种新的模型,确定矿井塌方风险指标体系因素查找原理,并对指标进行规范化处理,根据认定的矿井塌方风险指标比重,选取等级函数,通过博弈后,选择适当的效用参数因子分析博弈数据,确定矿井塌方风险内部因素影响效用与外部因素影响效用存在的矛盾性,以动态化的标准进行风险评估。实验结果表明,改进的矿井塌方风险评估模型得到的评估图像清晰可靠,评估结果准确率大幅度提高。
The mine is often affected by external environment and internal factor,but the impact is different.At present,the mine collapse risk assessment model has poor ability to collect data.It is impossible to study the data completely.It is difficult to achieve dynamic assessment,and the decision-making scheme is not scientific enough.Based on the traditional mine collapse risk assessment model,this paper designed a new model to determine the factor finding principle of mine collapse risk index system,and the indicators were standardized.According to the proportion of mine collapse risk indicators,the grading functions were selected.After the game,the appropriate utility parameters were selected to analyze the game data and determine the contradiction between the internal factors of mine collapse risk and the external factors,and thus to conduct the risk assessment based on dynamic criteria.Simulation results show that the improved model is clear and reliable,and the accuracy of assessment is greatly improved.
