Surface Ground Subsidence Law of Fully Mechanized Top Coal Caving Mining in Yanzhou Mining Area

为了研究综放开采地沉陷规律,根据兖州矿区建立的综放开采地表移动变形观测站和上覆岩层内部移动变形实测数据,在综合分析研究的基础上,获取了综放开采地表移动盆地特征及角值参数、地表动态移动规律及参数,揭示了综放开采地表动态变形规律和冲积层内部移动变形规律,建立了各种沉陷参数与地质采矿条件之间的变化关系式和开采沉陷概率积分预测参数体系。

In order to analyze the surface ground subsidence law of the fully mechanized top coal caving mining, according to the surface ground movement and deformation survey station of fully mechanized top coal caving mining established in Yanzhou Mining Area and the site measured data of the movement and deformation from the rock and soil, based on the comprehensive analysis study, the surface move- ment basin features and angle value parameters, the surface ground dynamic movement law and parameters of the fully mechanized top coal caving mining in the mining area were obtained. The surface ground dynamic deformation law of the fully mechanized top coal caving min- ing in the mining area and the inner movement and deformation law of the alluvium were also obtained. The variation relational expression between the different subsidence parameters and geological mining conditions, and the integral prediction parameter system of the mining subsidence probability were established.
