摘要
采空区域的稳定性评价受多种因素影响,缺乏统一的评价体系.本文以某煤矿开采工程为例,综合考虑地质条件、煤层结构、地表沉降等因素,构建了一个全面的评价指标体系,通过主成分层次聚类模型对采空区数据进行聚类分析,并与开采条件判别法进行比较验证.结果表明,主成分层次聚类模型评估结果能够有效反映采空区域的稳定性状况,并与开采条件判别法所得结论具有较高的一致性.本文为采空塌陷场地的管理和决策提供了一种科学、全面、可操作的评价体系,为煤矿安全和环境保护的可持续发展提供了技术支持.
Abstract
The stability evaluation of the goaf collapse area is affected by a variety of factors and lacks a unified evaluation system.In this paper,taking a coal mining project as an example,a comprehensive evaluation index system is constructed by comprehensively considers the factors such as geological conditions,coal seam structure,and surface subsidence,and the data of the goaf collapse area are clustered and analyzed through the principal component hierarchical clustering model,and then compared and verified with the mining condition discrimination method.The results show that the evaluation results of the principal component hierarchical clustering model can effectively reflect the stability of the goaf collapse area,and have a high consistency with the conclusion obtained from the mining conditions discrimination method.This paper provides a scientific,comprehensive and operable evaluation system for the management and decision-making of goaf collapse areas,and provides technical support for the sustainable development of coal mine safety and environmental protection.
