Abstract
The invention discloses a backfilling hardening method for open pit ore face sludge. The backfilling hardening method for the open pit ore face sludge comprises the following steps that firstly, damming is conducted on the periphery to block the sludge; secondly, a sand material applied to casting is discharged into a sludge pit defined by a dam to be mixed with the sludge. By the adoption of the backfilling hardening method, the characteristic that the sand material can neutralizes the sludge is utilized, the sand material applied to casting is mixed with the sludge according to a proportion, in this way, the water content of the sludge is reduced, the property of material is greatly improved, the sludge can be compacted and buried, and the compacted and buried sludge can be used as a foundation.
Description
Technical field
The present invention relates to opencast mining field, particularly a kind of backfill method for curing of outdoor ore faces mud.
Background technology
At present, each opencut is in time needing to lay various facility on mud, and the method extensively taked is, utilizes casting to build a dam body in mud surrounding, is prohibited within the specific limits by mud circle, then utilize the refuse dump discrepancy in elevation, presses the mode of burying to solve.
But the darker mud of on-the-spot mud foundation ditch is more sometimes, and casting cannot be pressed and be buried, on the contrary by more crowded for mud higher, finally overflow out of control.And this conventional method is directly pressed and is buried, and often can not meet the pressure-bearing needs as substrate.
The information being disclosed in this background technology part is only intended to increase the understanding to general background of the present invention, and should not be regarded as admitting or imply in any form that this information structure has been prior art that persons skilled in the art are known.
Summary of the invention
The object of the present invention is to provide a kind of backfill method for curing of outdoor ore faces mud of simple and reasonable steps, the backfill method for curing of this outdoor ore faces mud utilize sand material can in and the ins and outs of mud, material sand used for casting is mixed in proportion with mud, thus reduce mud water content, its material property is significantly promoted, can not only press and bury mud, and the position after pressure can be made to bury meet as the needs of substrate.
For achieving the above object, the invention provides the backfill method for curing of outdoor ore faces mud, comprise the following steps: first, surrounding is built a dam shutoff mud; Then, material sand used for casting is entered in the mud hole that dam body surrounds and mix with mud.
Preferably, in technique scheme, the mixed proportion of casting material sand used and mud is 4:1.
Compared with prior art, the present invention has following beneficial effect: the backfill method for curing of this outdoor ore faces mud utilize sand material can in and the ins and outs of mud, material sand used for casting is mixed in proportion with mud, thus reduce mud water content, its material property is significantly promoted, can not only press and bury mud, and the position after pressure can be made to bury meet as the needs of substrate.
Accompanying drawing explanation
Fig. 1 is that the surrounding of the backfill method for curing of outdoor ore faces mud of the present invention is built a dam schematic diagram;
Fig. 2 be material sand and the mud of the backfill method for curing of outdoor ore faces mud of the present invention mix schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of detailed description of the invention.
Clearly represent unless otherwise other, otherwise in whole manual and claims, term " comprise " or its conversion as " comprising " or " including " etc. by be understood to include the element of stating or ingredient, and do not get rid of other element or other ingredient.
According to the backfill method for curing of the outdoor ore faces mud of the specific embodiment of the invention by changing casting material, utilize sand material ins and outs, its can in and mud, reduce mud water content.Refer and synthesize in proportion.Mud water content reduces the most at last, its material property is significantly promoted, meets substrate needs.This backfill method for curing comprises the following steps:
First, surrounding is built a dam shutoff mud.
As shown in Figure 1, adopt surrounding to build a dam the mode of shutoff, namely to build a dam body 2 in the surrounding of mud 1, when extruding to prevent casting, mud is extruded.
Then, material sand used for casting is entered in the mud hole that dam body surrounds and mix with mud.
As shown in Figure 2, material sand 3 used for casting is entered in the mud hole 4 that dam body 2 surrounds, make material sand 3 be 4:1 with the mixed proportion of mud 1.Constantly be discharged into mud hole by sand, sand absorbs moisture and gets more and more, and mud water content is fewer and feweri, and material property is more and more stronger.Final satisfied with substrate needs.
To sum up, the backfill method for curing of this outdoor ore faces mud utilize sand material can in and the ins and outs of mud, material sand used for casting is mixed in proportion with mud, thus reduce mud water content, its material property is significantly promoted, can not only press and bury mud, and the position after pressure can be made to bury meet as the needs of substrate.
The aforementioned description to concrete exemplary of the present invention is to illustrate and the object of illustration.These descriptions not want the present invention to be defined as disclosed precise forms, and obviously, according to above-mentioned instruction, can much change and change.The object selected exemplary embodiment and describe is to explain certain principles of the present invention and practical application thereof, thus those skilled in the art can be realized and utilize various different exemplary of the present invention and various different selection and change.Scope of the present invention is intended to limited by claims and equivalents thereof.
