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, technical field of environmental management, be specifically related to a kind of surface mine refuse dump slope treatment method.
Background technology
Mining mainly contains the surface mining mining mode different with underground mining two kinds, the outdoor stripping during comprising mine capital construction and excavation developing; Dumping thing generally has corruption to plant table soil, weathered rock and soil, solid rock and mixing ground, and sometimes also comprising can recoverable unbalanced-ore, lean ore etc.When ore body bury more shallow or earth's surface have appear time, application strip mining transformation (surface mining) is the most superior.Compared with underground mining, strip mining transformation advantage is that the utilization of resources is abundant, high stoping rate, the rate of dilution are low, and be suitable for big machinery construction, build ore deposit fast, output is large, and labor productivity is high, and cost is low, and condition of labor is good, production safety.But need to dump a large amount of rocks, especially darker opencut, often take more farmland.
Refuse dump (dump), also known as waste-rock yard, refers to that mining dumps the place that thing concentrates discharge.Refuse dump is a kind of huge artificial loose heap pad, there is serious potential safety hazard.Refuse dump unstability will cause mine soil field disaster and Important Project accident, not only have influence on the normal production in mine, also will mine be made to suffer huge economic loss.Meanwhile, the soil erosion of refuse dump and barren hill make again ecological environment become bad.
Summary of the invention
The present invention is directed to the deficiencies in the prior art and provide 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, being arranged by grade of side slope is 1: 1.5-1: 3, and cohesive soil gets 1: 1.5, and grit stone gets 1: 3, and other great soil group gets median; Build platform (2): vertical height often rising 6-12m builds levelling bench, and width is 5m; Build horizontal drainage ditch (3): in the middle part of platform, build horizontal drainage ditch, discharge section is trapezoidal, bottom width 1m, top width 2m, height 1m, with concrete precast block lining cutting or build; Build drain way (4): horizontal direction builds one perpendicular to the drain way of horizontal drainage ditch, in order to drain the current in horizontal ditch every 30m on domatic; Top, refuse dump is trimmed to certain slope, is convenient to rain drainage, the gradient depending on location precipitation size, northern α=2-3 °, southern α=3-5 °; If top, the refuse dump gradient does not reach aforementioned claim, build net of canals and ditches (6) at top, so that the excretion of rainfall runoff quick collecting, directly excavate and form, not lining cutting, and be connected to drain way; Vegetation slope pavement: be prevention soil and water loss, stable side slope, side slope is planted shrub (7), utilizes its root system soil and slope protection; Top, refuse dump plantation arbor.
Advantage of the present invention is: transformed by limited engineering and biological control measure on original refuse dump, can effect a radical cure the potential safety hazard of surface mining refuse dump, soil erosion greatly be alleviated, improves the ecological environment, beautify mining area and surrounding enviroment.Have small investment, the feature that the duration is short, because structure is simple, later maintenance expense is low simultaneously.
Accompanying drawing explanation
Fig. 1 is the inventive method schematic diagram.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.
By with reference to figure 1, renovate side slope 1: being arranged by grade of side slope (tangent value of slope angle) is 1: 1.5-1: 3, and cohesive soil gets 1: 1.5, and grit stone gets 1: 3, and other great soil group gets median.
Build platform 2: the vertical height 6-12m (cohesive soil gets 12m, and grit stone gets 6m, and other great soil group gets median) that often rises builds levelling bench, and width is 5m.
Build horizontal drainage ditch 3: in the middle part of platform, build horizontal drainage ditch, discharge section is trapezoidal, bottom width 1m, top width 2m, height 1m, with concrete precast block lining cutting or build.
Build drain way 4: horizontal direction builds one perpendicular to the drain way of horizontal drainage ditch, in order to drain the current in horizontal ditch every 30m on domatic.Section configuration, size and lining cutting mode are the same.
Top, refuse dump is trimmed to certain slope, is convenient to rain drainage, the gradient depending on location precipitation size, northern α=2-3 °, southern α=3-5 °.If top, the refuse dump gradient does not reach aforementioned claim, build net of canals and ditches 6 at top, so that the excretion of rainfall runoff quick collecting, directly excavate and form, not lining cutting, and be connected to drain way.
Vegetation slope pavement: be prevention soil and water loss, stable side slope, side slope is planted shrub 7, utilizes its root system soil and slope protection; Top, refuse dump plantation arbor, density, depending on tree characteristics, under its normal growing conditions, adopts dense planting.Seeds select local autochthonal seeds, can ensure survival rate.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
