摘要
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 safety of steep coal-goal, this paper analyzed geological characteristics of steep coal diggings and stability influence factors, according to temporal and spatial thinking, and established a stability evaluation index system, which covers three second rank indexes and seven third rank indexes. The information fusion model of stability evaluation was built in steep coal-goaf combining D-S evidence theory with constructing probability distribution function based on information distribution and diffusion principle. Taking a mine as a practical example, the result shows that informationfusion model is adapted to the safety evaluation model of steep coal-goaf and also holds considerable reference to the mine evaluation with similar geological environment.
