摘　　要：针对条带采空区在大埋深条件下的稳定性问题,以开采条件、稳定性地表变形、煤柱稳定性等判别因素,对岱庄煤矿采空区进行了稳定性评价。为保障场地安全及以后的建设使用,以场地稳定性及工程重要程度判别、工程类比法、采空区特征及活化影响因素分析法、地表剩余移动变形判别法等方法进行采空区场地对工程建设的影响评价,来评价场地建设利用的适宜性;适应建设规划的采空区治理标准和处理方法,有利于整体的沉陷治理和建设再利用过程。Aiming at the stability problem of strip mined-out area under the condition of large buried depth, the stability evaluation of mined-out area in Daizhuang coal mine was carried out by using mining conditions, stable surface deformation and coal pillar stability. In order to ensure the safety of the site and the subsequent construction and utilization, the site stability and the importance of the project, the engineering analogy method, the analysis method of the characteristics of the goaf and the influencing factors of the activation, and the discrimination method of the surface residual movement deformation are used to evaluate the influence of the goaf site on the engineering construction, so as to evaluate the suitability of the site construction and utilization. The goaf treatment standards and treatment methods adapted to the construction planning are conducive to the overall subsidence control and construction reuse process.
