Abstract

The invention discloses a large area penetrating goaf bag-type filling treating method by areas and by steps. The filling treating method comprises the following steps that a, according to the occurrence situations of a goaf and ore pillars, the goaf is divided into partitions to be filled and blank leaving partitions; b, strip-shaped bag-type filling blocking walls are constructed on the outer periphery of the partitions to be filled; c, the partitions to be filled are filled by steps according to treating orders; and d, filling treating by areas and by steps of the goaf is completed. The technical problems that the blocking and filling treating process of the large area penetrating goaf cannot be controlled, the filling quality is poor and the treating effect is poor are solved. The potential safety hazard of the large area goaf can be eliminated by steps; the influence of the goaf on the earth surface and regional geologic environment can be controlled, and safety accidents caused by the goaf are avoided. The filling treating method is suitable for treating of large area penetrating goafs, especially for gently-inclined ore bodies, and treating of goafs exploited through a room-and-pillar method and a comprehensive method.

Description

technical field [0001] The invention relates to the technical field of goaf treatment in mines, in particular to a step-by-step filling treatment method for large-area through-goaf pockets. Background technique [0002] According to the current goaf treatment methods adopted by mines at home and abroad, they can be comprehensively classified into: filling goaf treatment, caving surrounding rock treatment goaf, leaving permanent ore pillars to support goaf, isolation and dredging goaf The first four types are the most basic goaf processing methods, and the combined method uses the above-mentioned methods to jointly process goafs. [0003] The room-and-pillar mining method generally uses permanent pillars to support the goaf. However, in recent years, large-scale goafs have collapsed, and caving accidents have occurred frequently. For example, in 2016, the "12.25" gypsum mine in Pingyi County, Linyi City, Shandong Province Collapse accidents, etc. These accidents have caused ...
