Research on surface subsidence prediction model of coal mining with solid compacted backfilling
In order to achieve predicting the surface subsidence caused by solid compacted backfilling mining scientifically
it is necessary to establish the completed prediction model and its parameter system according to the evolvement rule of the structure form and movement characteristics of overburden rock. By means of similar material simulation and borehole peep
it is shown that overburden rock of mining with solid compacted backfilling is given priority to sagging zone
which appears complete layer structure
only develops some height of the fault zone near the roof strata
but not caving. The strata movement characteristic is similar to bending deformation of the laminated plates under the longitudinal loading
after a simplified mechanics. Based on the theory of laminated plates
surface subsidence prediction model of mining with solid compacted backfilling is established. It is shown that surface subsidence form of mining with solid compacted backfilling is still suitably described with probability integral model; and further discuss on parameters system of the surface subsidence prediction mode based on “equivalent mining thick” theory is carried out. Finally
the surface subsidence prediction model is applied to a real project
