The coconut shred nutrient blanket is extended outside the planting area because the soil of the refuse dump is improved, and the coconut shred blanket can be degraded along with time, so that the mine soil environment is changed. The BOP tension net is mainly used for strengthening the strength of the coconut fiber nutrition blanket, improving the integrity of the blanket-shaped structure of the coconut fiber nutrition blanket and facilitating transportation.
In a second embodiment, as shown in fig. 5, a method for reconstructing vegetation in a refuse dump of an open pit coal mine by using the buried ecological restoration module includes the following steps:
step 1, digging a strip-shaped ditch in a refuse dump platform area by using an excavator, and sequentially connecting a plurality of prefabricated buried ecological restoration modules along the length direction and placing the modules into the ditch to form a plurality of planting grooves;
step 2, placing the excavated soil in a non-planting groove area, and raising the excess soil above the non-planting groove area to form a slope of 3% -5%, so that water flow can conveniently flow into the planting grooves, and grass seeds are sowed in the non-planting groove area;
and 3, planting the plants with the soil balls in the planting groove area, and backfilling and planting the waste of the refuse dump with the particle size of 0.5-10 mm in the planting groove area.
As a further improvement, the coconut shred nutrition blanket can be arranged at the bottom of a vegetation planting block of the buried ecological restoration module.
In conclusion, the object of the present invention is achieved.
