英文摘要Long-term field monitoring finds that serious surface subsidence can still occur even if the high strength cemented fill method is adopted. Combining the results of numerical simulations with global position system (GPS) monitoring, we took a typical filling mining mine with a steeply inclined ore body as an example, and explored its ground subsidence mechanism. The results show that the ground subsidence caused by the mining of steep ore body is characterized by two settlement centers and a significantly uneven spatial distribution, which is visibly different from ground subsidence characteristic of the coal mine. The subsidence on the hanging wall is much larger than that on the footwall, and the settlement center tends to move to the hanging wall with the increase of mining depth. The backfill improves the strength and surrounding rock bearing capacity, which leads to a lag of about 3 years of the subsidence. However, under the actions of continuous and repeated mining disturbances, the supporting effect of the backfill can only reduce the amplitude of the deformation, but it cannot prevent the occurrence of settlement.
