摘要
通过对表土层及基岩结构的分析,提出了对地表沉陷主要影响因素的判别方法,给出了判别公式,并以山西天地王坡煤业有限公司综放工作面为研究对象,分析了工作面上覆基岩关键层结构、位置及表土层结构。同时通过地表监测,给出了地表移动变形特征参数,验证了判别方法的正确性。
Through analyzing structure of surface soil layer and bedrock, this paper was proposed a discrimination method of main influence factors of surface subsidence, and discrimination formula was put forward. Taking fully mechanized caving faces of Shanxi Tiandi Wangpo Coal Industry Co., Ltd. as research object, this paper was analyzed structure and location of key stratum and the structure of surface soil layer. Besides, through surface monitoring, the parameters of ground movement and deformation was given, which verified correctness of discrimination method.
