采动区建筑物移动变形规律实测研究

Study on the Movement and Deformation Law of Buildings in Mining Area by Observation

为了研究开采影响下的建筑物移动变形规律、指导矿井安全生产,兴隆庄煤矿专门在4326综放工作面上方设立建筑物移动观测站。通过对观测资料的分析研究,获得该区条件下建筑物的移动变形规律,给出建筑物移动变形与地表移动变形之间的单因素系列关系式,并总结了不同长高比条件下建筑物变形与地表变形之间的综合关系式,获得的一些有益成果为矿区建筑物下安全采煤及采动区建筑物保护设计提供了科学依据。

In order to study the law of buildings＇ movement and deformation caused by mining and guide safety production of the mine, Xinlongzhuang Coal Mine specially set up building movement observation station over coal mining face 4326. By analyzing and studying the observed data, the movement and deformation law of buildings in this area was obtained; a series of monofactorial expressions between building deformation and ground deformation were achieved. Furthermore, comprehensive relation expressions be- tween building deformation and ground deformation were concluded and summarized under the condition of different length-height ratio. This study will provide solid basis for the safety of mining under buildings and the protection designing of building in mining area.
