Abstract
The invention discloses a kind of processing method of open-pit mine blast greening bench face, comprise the following steps：Step 1, the shoulder height h of step to be afforested and original domatic angle [alpha] are obtained；Step 2, when original domatic angle [alpha] >=30 °, slope surface treatment operation is proceeded by；Step 3, the domatic angle beta after slope surface treatment operation is determined, the extended distance d of face toe needs is calculated according to domatic angle [alpha], β and shoulder height h；Step 4, according to the extended distance d in step 3, select suitable equipment to treat greening step and carry out slope surface treatment operation；Step 5, the domatic of new formation after slope surface treatment operates is afforested.The processing method can improve greening work efficiency, and largely reduce souring of the rainwater to slope greening, so as to contribute to the long-term preservation of opencut greening work achievement.
Description
Technical field
A kind of processing method the present invention relates to opencut to boundary refuse dump greening bench face.
Background technology
Opencut greening work in China's is highly valued in recent years, and greening technique is quickly grown.Due to opencut to boundary
Refuse dump is acted on by wind and rain all the year round, easily produces airborne dust and bench face is subject to heavy damage, thus to ring around mining area
Border produces ill effect, while have impact on the normal life of mining area surrounding resident, therefore opencut is controlled to boundary refuse dump
Manage particularly significant.
Being in progress to the greening work of boundary's casting step for current domestic opencut is rapid, but due to the original slope of casting step
Face angle degree is big, thus very big difficulty is brought to greening work personnel and its equipment, the effect of rain drop erosion in addition, and leads
Causing the greening soil of greening bench face Surface mulch can not deposit for a long time, so as to have a strong impact on the long-term preservation of Result of afforestation.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
A kind of processing method it is an object of the invention to provide opencut to boundary refuse dump greening bench face, so that gram
Take the problem of being difficult to protect opencut Result of afforestation in existing method.
To achieve the above object, the invention provides the processing method of open-pit mine blast greening bench face, including such as
Lower step：
Step 1, the shoulder height h of step to be afforested and original domatic angle [alpha] are obtained；
Step 2, when original domatic angle [alpha] >=30 °, slope surface treatment operation is proceeded by；
Step 3, the domatic angle beta after determining slope surface treatment operation is calculated by analyzing, according to domatic angle [alpha], β and step
Height h calculates the extended distance d of face toe needs；
Step 4, according to the extended distance d in step 3, select suitable equipment to treat greening step and carry out the domatic place
Reason operation；With
Step 5, the domatic of new formation after slope surface treatment operation is afforested.
Preferably, in above-mentioned technical proposal, step, equipment is crawler dozer in 3.
Preferably, in above-mentioned technical proposal, the slope surface treatment operation of step 4 is from face toe extended distance d end
Bulldozed towards domatic direction, be compacted process, it is new domatic so as to be formed.
Compared with prior art, the present invention has the advantages that：Greening work efficiency, and very great Cheng can be improved
Degree reduces souring of the rainwater to slope greening, so as to contribute to the long-term preservation of opencut greening work achievement.

Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
The processing method of the open-pit mine blast greening bench face of the present invention, comprises the following steps：
Step 1, step shoulder height h to be afforested and original domatic angle [alpha] are obtained；
Step 2, when original domatic angle [alpha] >=30 °, slope surface treatment operation is proceeded by；
Step 3, the domatic angle beta after slope surface treatment operation is determined, is calculated according to domatic angle [alpha], β and shoulder height h
The extended distance d that face toe needs；
Step 4, according to the extended distance d in step 3, select suitable equipment to treat greening step and carry out the domatic place
Reason operation；With
Step 5, the domatic of new formation after slope surface treatment operation is afforested.
Wherein, equipment is crawler dozer in step 3.
Wherein, the slope surface treatment operation of step 4 is carried out from face toe extended distance d end towards domatic direction
Bulldoze, compacting process, it is new domatic so as to be formed.
It according to the original domatic angle of the present invention is 30 ° that Fig. 1, which is, and shoulder height is 20 meters of step to be afforested through step slope
The contrast schematic diagram of face before and after the processing.
The shoulder height h for measuring greening step first is 20 meters, and domatic angle [alpha] is 30 °, it is therefore desirable to carries out slope surface treatment
Operation；
It is 15 ° by analyzing the domatic angle beta calculated after determining slope surface treatment operation, is gone out by α, β and h numerical computations
The extended distance d that face toe needs is 40 meters.
Bulldozed, be compacted towards domatic direction from face toe extended distance d end using crawler dozer
Operational sequence, it is new domatic so as to be formed.
Finally, newly formed it is domatic on afforested, can select non-rock high gradient slope non-woven bag greening technique,
Planting groove slope protection greening technology, reinforced concrete frame banket in bulkhead tech and side slope anchor pole thick photoresist spray seeding technique one
Kind.
Greening work efficiency can be improved using the processing method of the open-pit mine blast greening bench face of the present invention, and
And souring of the rainwater to slope greening is largely reduced, so as to contribute to the long-term guarantor of opencut greening work achievement
Deposit.
The description of the foregoing specific illustrative embodiment to the present invention is to illustrate and the purpose of illustration.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can be much changed
