Description
Technical field
The present invention relates to mining technique fields, and in particular to a kind of packed filling mining method.
Background technique
Mining methods occupy highly important status in mining production, are to directly affect mine production rate, ore damage
The key for the problems such as losing dilution, labor productivity, production cost, economic benefit and operation safety.In medium-and-large-sized underground mine,
Cut-and-fill Mining Technology is often used, this technical method filling cost is high, and complex process and mechanization degree height need in supporting
A large amount of timber supportings, cause a large amount of waste to timber, it is therefore necessary to a kind of packed filling mining method is provided, so that not
It is only capable of save the cost, and safety coefficient and recovery rate in ore-dressing can also be greatly improved.
Summary of the invention
The purpose of the present invention is to provide a kind of packed filling mining methods, after the filling of packed filling material protective edge, no
But enhance the adaptability changed to ore body, it is also larger to improve worker in the safety coefficient of working face, meanwhile, utilize the method
Recovery rate in ore-dressing can be effectively improved.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of packed filling mining method, including following technique:
(1) early-stage preparations: in one return air raise of stope center arrangement, this well rises from upper layer-by-layer disappearance, lower section with layering, by
Layer welding installation steel chute respectively arranges a filling well in stope both wings as mine chute；
(2) first layer process for stoping: arranging a phase route and the second stage of route by the thickness of ore body, first pick by lower wall route with
Well connection is filled, then digs filling connecting taxiway, then adopts a phase route, a phase route adopts the second stage of route after having adopted Tight filling again,
The second stage of route fills 1.5m after having adopted, and after having set up steel chute, the second stage of route and connecting taxiway is even uniformly chooses high 1.5m, complete quarrel is sub out
It has set up steel chute again afterwards, has then refilled 1.5m, first layer back production terminates；
(3) second slicing techniques: second is layered the high 1.5m that rises again on the basis of the second stage of route of first layer, is formed
For a phase route, wall rib is built into the packed filling material pile of cement of filling dress cement when a phase admission passage filling；
(4) fill process: it is clean by ore manual cleaning is remained in route after drift stoping is complete, in route inlet cement
Packed filling material buttress is thorough can be filled at wall, and the material of filling selects the useless quarrel of dense media, thick tailings and silicon after desliming
Acid salt cement.
Further, in first layer filling process, the proportion of fill material are as follows: portland cement: thick tailings: useless quarrel
=1:2:8, first layer are protrusive filling.
Further, in the second layering filling process, the proportion of fill material are as follows: portland cement: thick tailings: useless quarrel
=1:3.2:15, the second layer are retrusive filling.
Further, the steel chute is rolled with the steel plate of 5mm.
Further, the size of the return air raise is 1.8m × 1.8m, and the size for filling well is 2.2m × 2m.
Compared with prior art, the present invention be at least able to achieve it is following the utility model has the advantages that
1, after the present invention is using the filling of packed filling material protective edge, not only enhances the adaptability to ore body variation, also improve work
The safety coefficient for making face ensure that the connection of filling well and returnairshaft, also ensured and filled due to doing wall with the packed filling material of cement
Fill out the exit passageway of working face；
2, replace the supporting of part timber with filling and support, save the use of timber, while using useless quarrel as filler, avoid
The accumulation of useless quarrel, has saved tailings glass expense；
3, stablized with the wall that the packed filling material branch of cement is built, be not easy to be caving, reduce the rate of dilution, be conducive to improve ore dressing recycling
Rate.
