为评价陡煤采空区稳定性,分析了陡煤矿区地质特点和稳定性影响因素,根据时空观思想建立了由3个二级指标和7个三级指标构成的稳定性评价指标体系;利用信息分配和信息扩散原理构造概率分配函数,结合D-S证据推理理论,建立了陡煤采空区稳定性评价的信息融合模型.验证了信息融合模型对陡煤矿山采空区稳定性评价是适应的.该方法对类似地质条件的矿山采空区稳定性评价具有借鉴作用.
In order to evaluate the stability of steep coal mined-out area, the paper analyzes the geological characteristics and the influencing factors of steep coal mining area, and establishes the stability evaluation index system composed of three second-level indexes and seven third- Information Assignment and Information Diffusion Theory, the information fusion model for the stability assessment of steep coal goaf is established based on DS evidence reasoning theory, and the information fusion model is validated to evaluate the stability of steep coal mine goaf. This method can be used as a reference for the stability evaluation of goafs with similar geological conditions.
