摘要
解决开采沉陷动态预计的规律性问题,必须把地质实测经验资料和采场覆岩移动变形力学机制有机地结合起来。用流变力学原理推导地表动态移动下沉值与时间的函数关系式,结合现场实测资料对相关系数进行估算,可以有效地对开采地表变形进行预计,有助于确定地表受采动的影响程度。
Solving the regularity problem of the mining settlement dynamic estimation must make organic combination of the geological actual empirical data with the mining field overlaying rock's moving deformation mechanical mechanisms. Deducing the relational expression of the dynamic subsidence value and the time by using the rheo-mechanics principle and making estimation of the correlation coefficient connecting with the field-measured data can estimate the mining subsidence effectively, which is helpful to determine the extent of the influence of the mining on the ground surface.
