Description

A kind of method that the filling of goaf part is carried out according to earth's surface subsidence
Technical field
The present invention relates to a kind of method that the filling of goaf part is carried out according to earth's surface subsidence, belongs to filling mining neck Domain.
Background technology
For a long time, China is generally using the goaf of caving method processing underground mineral resources, the method mechanization degree It is higher with production efficiency, but overlying rock deformation on a large scale is also resulted in being caving, roof fracture is permeable is broken with lithic drainage for initiation Environment and the safety such as bad, subsidence and buildings or structures destroy, the accumulation of spoil ground, the irregular accumulation of goaf pernicious gas Problem.Meanwhile China, there is substantial amounts of " under three " resource, under the present situation of resource increasingly depleted, this part resource is urgently It is released utilizing.The method of subsidence is controlled mainly to have partial mining and filling mining in underground mineral resources exploitation, or Both combinations, traditional partial mining method includes room mining, Striping noise, pillar-and-panel work etc., be required for staying set it is big The ore pillar of amount, recovery ratio is low, causes a large amount of wastes of underground mineral resources, it is difficult to effectively solves the exploitation of resource " under three " and asks Topic.In recent years, under the theory of " lasting exploit " and the promotion of Mining Policy, filling mining is as control environmental disruption and solution The means of " under three " resource exploitation, develop rapidly in mining engineering, and in obturation arrangement, filler, fill Technique etc. is filled out to make some progress.
The best mode filled to goaf is to adopt to fill entirely entirely, i.e., as far as possible by filler full of whole mined out Area, the mineral products being produced out are replaced with filler, control the migration of overlying rock.Complete adopt fills the control that can reach good entirely Effect, but substantial amounts of filler is needed, filling cost is higher.Meanwhile as the improvement of production practice and filling mining are quick Development, it is available mining solid waste constantly reduce, cannot little by little meet to adopt the needs of filling entirely entirely.How to solve to dig up mine Balance between solid waste quantum of output and filler demand, becomes current and filling mining from now on main problem. Therefore, on the basis of Quan Caiquan fills, to reduce filler usage amount, reducing filling cost, part is carried out to goaf and is filled Fill out.Part, which fills common mode, strip-type filling and pier stud type filling etc., although these filling methods have saved filling material Material, but planning is filled due to lacking rational adopt, filling is in the form of a single, and filling effect is not ideal, and roof deformation amount is difficult to control System.For coal mine filling exploitation there are the problem of, goaf part fill thought on the basis of, it is proposed that according to roof caving The method that feature prediction carries out goaf part filling mining.
The content of the invention
The present invention is intended to provide a kind of method that the filling of goaf part is carried out according to earth's surface subsidence, according to exploitation ground Table subsidence, fills planning by predicting and adopting early period, obturation of different shapes is targetedly arranged in goaf, is controlled The deformation failure and subsidence of top plate, are allowed to form " obturation-top plate " structure control system, and control overlying rock deformation is broken Bad and subsidence.
It is including following interior the present invention provides a kind of method that the filling of goaf part is carried out according to earth's surface subsidence Hold:
Surface subsidence isopleth is drawn according to mining apparent mining damage method for predicting, is carried out in the range of central area complete Portion fills, control depression center;Some circle filling bands are arranged outside the scope all filled, control depression large area; Fill band disposed outside number and arrange filling monomer of different shapes, control depression fringe region;Special geological structure position into Row all fillings, proof stress centrostigma;Arrange narrow filling band gob side entry retaining, reduce subsequent work Mian Jue lanes workload, And close bashing.Fill band and fill the stabilization of monomer controlroof, form " obturation-top plate " structure control body System, controls the deformation failure and subsidence of overlying rock.
