摘　　要：为系统掌握综放开采条件下地表移动变形规律和机理,某煤矿于2018年初建立了E2307综放工作面地表岩移观测站,结合工作面具体概况,在对现场进行实地观测和资料分析的基础上,结合理论分析、数值模拟计算,求取了某煤矿特定地质采矿条件下的岩移参数和岩移角值,揭示了该矿厚松散层综采放顶煤条件下地表沉陷变形规律,为某煤矿今后开展村庄下、水体下、铁路下、公路下采煤以及合理留设保护煤柱提供了科学依据,同时丰富了我国“三下”采煤关于综放开采沉陷领域研究成果。In order to systematically grasp the dynamic law and mechanism of surface movement and deformation under the conditions of fully mechanized top-coal caving mining,a coal mine established the E2307 surface rock movement observation station at the beginning of 2018.Based on the specific situation of the working face,based on the field observation and data analysis,combined with theoretical analysis and numerical simulation calculation,the rock movement parameters and rock movement angle values under the specific geological mining conditions of a coal mine were obtained,it has revealed the law of surface subsidence and deformation under the condition of fully mechanized top-coal caving in the thick loose layer of the mine,provided scientific basis for a coal mine to carry out coal mining under villages,water bodies,railways and highways in the future and to reasonably reserve protective coal pillars,and enriched the research results of the"three lower"coal mining in the field of fully mechanized top-coal caving subsidence.
