Abstract
The invention discloses a method for treating a dump slope of a surface mine. The method comprises the following steps of: treating to ensure that the side slope grade is (1:1.5)-(1:3), wherein if the slope is cohesive soil, the side slope grade is 1:1.5; if the slope is gravel, the side slope grade is 1:3; if the slope is other soil, the side slope grade is (1:1.5)-(1:3); building platforms (2), namely building a horizontal platform every 6 to 12 meters in the vertical height, wherein the width of the platform is 5 meters; building horizontal a drainage ditches (3), namely building the horizontal drainage ditches in the middles of the platforms; building discharging ditches (4), namely building the discharging ditch perpendicular to the horizontal drainage ditch every 30 meters on the slope surface in the horizontal direction, wherein the slope grade is determined according to the rainfall of the place where the slope is, the slope grade a in the north is 2 to 3 degrees, and the slope grade b in the south is 3 to 5 degrees; if the slope grade on the top of a dump cannot meet the requirement, building a canal and ditch net (6) on the top; and growing plant to protect the slope. The conventional dump is transformed by limited engineering and biological control measures, the potential safety hazard of strip mining dumps can be avoided completely, the water losses and soil erosion can be reduced greatly, ecological environment is improved, and mining areas and the environment around the same can be beautified. Meanwhile, the method has the characteristics of low investment and short construction period; and the structure is simple, so that later-stage maintenance cost is low.
Description
Technical field
The invention belongs to mine construction, environmental improvement technical field, be specifically related to a kind of surface mine refuse dump slope treatment method.
Background technology
Mining mainly contains two kinds of different mining modes of surface mining and underground mining, comprises peeling off with excavation during the mine capital construction in the open and opens up; Dumping thing generally has corruption to plant table soil, weathered rock and soil, solid rock and mixing ground, and also comprising sometimes can recoverable unbalanced-ore, lean ore etc.When ore body buries more shallow or there is when appearing on the face of land, it is the most superior to use strip mining transformation (surface mining).Compare with underground mining, the strip mining transformation advantage is that the utilization of resources is abundant, the rate of extraction is high, the rate of dilution is low, is suitable for the big machinery construction, and it is fast to build the ore deposit, and output is big, and labor productivity is high, and cost is low, and condition of labor is good, production safety.But need dump a large amount of rocks, especially darker opencut often takies more farmland.
The refuse dump (dump) claim waste-rock yard again, is meant that mining dumps the place that thing is concentrated discharging.The refuse dump is the loose heap pad of a kind of huge manual work, has serious potential safety hazard.The refuse dump unstability will cause a mine soil disaster and Important Project accident, not only have influence on the ordinary production in mine, also will make the mine suffer enormous economic loss.Simultaneously, the soil erosion of refuse dump and barren hill make ecological environment become bad again.
Summary of the invention
The deficiency that the present invention is directed to prior art provides a kind of surface mine refuse dump slope treatment method.
The present invention adopts following technical scheme:
A kind of surface mine refuse dump slope treatment method is 1 with the grade of side slope arrangement: 1.5-1: 3, and cohesive soil was got 1: 1.5, and grit stone was got 1: 3, and other great soil group is got median; Build platform (2): the every rising 6-12m of vertical height builds levelling bench, and width is 5m; Build horizontal rows ditch (3): build the horizontal rows ditch at the platform middle part, discharge section is trapezoidal, bottom width 1m, and top width 2m, height 1m is with the concrete precast block lining cutting or build; Build drain way (4): horizontal direction is every on domatic builds a drain way perpendicular to the horizontal rows ditch at a distance from 30m, in order to drain the current in the horizontal ditch; The top, refuse dump is trimmed to certain slope, is convenient to rain drainage, and the gradient is looked location precipitation size and decided, and northern α=2-3 °, southern α=3-5 °; If top, the refuse dump gradient does not reach aforementioned requirement, build net of canals and ditches (6) at the top, so that rainfall runoff compiles drainage fast, directly excavation forms, not lining cutting, and be connected to drain way; Vegetation slope pavement: be prevention soil and water loss, stable side slope is planted shrub (7) on side slope, utilize its root system soil and slope protection; The plantation arbor at the top, refuse dump.
Advantage of the present invention is: on original refuse dump through limited engineering and biological control measure transformation, can effect a radical cure the potential safety hazard of surface mining refuse dump, soil erosion is greatly alleviated, improve the ecological environment, beautify mining area and surrounding enviroment.Have small investment simultaneously, the characteristics that the duration is short, because simple in structure, the later maintenance expense is low.
Description of drawings
Fig. 1 is the inventive method sketch map.
The specific embodiment
Below in conjunction with specific embodiment, the present invention is elaborated.
Press with reference to figure 1 regulation side slope 1: with grade of side slope (tangent value of slope angle) arrangement is 1: 1.5-1: 3, and cohesive soil was got 1: 1.5, and grit stone was got 1: 3, and other great soil group is got median.
Build platform 2: the every rising 6-12m of vertical height (cohesive soil is got 12m, and grit stone is got 6m, and other great soil group is got median) and build levelling bench, width is 5m.
Build horizontal rows ditch 3: build the horizontal rows ditch at the platform middle part, discharge section is trapezoidal, bottom width 1m, and top width 2m, height 1m is with the concrete precast block lining cutting or build.
Build drain way 4: horizontal direction is every on domatic builds a drain way perpendicular to the horizontal rows ditch at a distance from 30m, in order to drain the current in the horizontal ditch.Section configuration, size and lining cutting mode are the same.
The top, refuse dump is trimmed to certain slope, is convenient to rain drainage, and the gradient is looked location precipitation size and decided, and northern α=2-3 °, southern α=3-5 °.If top, the refuse dump gradient does not reach aforementioned requirement, build net of canals and ditches 6 at the top, so that rainfall runoff compiles drainage fast, directly excavation forms, not lining cutting, and be connected to drain way.
Vegetation slope pavement: be prevention soil and water loss, stable side slope, plantation shrub 7 utilizes its root system soil and slope protection on side slope; The plantation arbor at the top, refuse dump, density is looked tree characteristics and is decided, and under its normal growth condition, adopts dense planting.Seeds are selected local autochthonal seeds for use, can guarantee survival rate.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
