Description

A kind of method carrying out goaf part filling according to earth's surface subsidence
Technical field
The present invention relates to a kind of method carrying out goaf part filling according to earth's surface subsidence, belong to filling mining neck Territory.
Background technology
For a long time, the commonly used caving method of China processes the goaf of underground mineral resources, the method mechanization degree Higher with production efficiency, but also result in overlying rock and deform on a large scale and be caving, cause roof fracture permeable broken with lithic drainage Environment and the safety such as bad, subsidence and buildings or structures destruction, the accumulation of spoil ground, the irregularly accumulation of goaf harmful gas Problem.Meanwhile, China also exists substantial amounts of " three times " resource, and under the present situation that resource is day by day exhausted, this part resource is urgently It is released utilizing.The method controlling subsidence in underground mineral resources exploitation mainly has partial mining and filling mining, or Being both combinations, traditional partial mining method includes room mining, Striping noise, pillar-and-panel work etc., be required for staying set big The ore pillar of amount, recovery ratio is low, causes a large amount of wastes of underground mineral resources, it is difficult to the exploitation effectively solving " three times " resource is asked Topic.In recent years, under the theory of " lasting exploit " and the promotion of Mining Policy, filling mining is as controlling environmental disruption and solution The means of " three times " resource exploitation, develop rapidly in mining engineering, and at obturator arrangement, filler, fill Fill out the aspects such as technique to make some progress.
The best mode that goaf carries out filling is entirely to adopt entirely to fill, and is full of by filler whole mined out the most as far as possible District, replaces the mineral products being produced out with filler, controls the migration of overlying rock.Entirely adopt and entirely fill the control that can reach good Effect, but need substantial amounts of filler, filling cost is higher.Meanwhile, quick along with improvement and the filling mining of production practice Development, available mining solid waste constantly reduces, and little by little can not meet and entirely adopt the demand entirely filled.How to solve mining Balance between solid waste quantum of output and filler demand, becomes current and filling mining from now on subject matter. Therefore, on the basis of Quan Caiquan fills, for reducing filler usage amount, reducing filling cost, goaf is carried out part and fills Fill out.The mode that part filling is commonly used has strip-type filling and pier stud type filling etc., although these filling methods have saved filling material Material, but fill planning owing to lacking reasonably to adopt, and filling form is single, and filling effect is not ideal, and roof deformation amount is difficult to control System.The problem existed for coal mine filling exploitation, on the basis of the part filling thought of goaf, it is proposed that according to roof caving Feature predicts the method carrying out goaf part filling mining.
Summary of the invention
It is desirable to provide a kind of method carrying out goaf part filling according to earth's surface subsidence, according to exploitation ground Table subsidence, is predicted by early stage and adopts and fill planning, arranges difform obturator targetedly in goaf, controls The deformation failure of top board and subsidence, be allowed to be formed " obturator-top board " structure control system, controls overlying rock deformation broken Go bad and subsidence.
