Embodiment 1

[0027] First pour the covering soil from the top layer to the next step one by one, the thickness of the covering soil is 100cm, then clean up the stones on each layer of slope and steps in turn, level the slope and the covering soil on the steps, and finally carry out layered rolling on the stones of the bottom step 3 Second, level the soil.

[0028] Using the method of the present invention to cover the soil, after 7 days of scouring and settlement, the thickness of the slope's covering soil is 90 cm, the thickness of the step's covering soil is 98 cm, and the thickness of the bottom layer of covering soil is 93 cm.

Embodiment 2

[0030] First pour the covering soil from the top layer to the next step, the thickness of the covering soil is 100cm, then clean up the stones on each layer of slope and steps in turn, level the slope and the covering soil on the steps, and finally carry out layered rolling on the stones of the bottom step5 Second, level the soil.

[0031] Using the method of the present invention to cover the soil, after 7 days of scouring and settlement, the thickness of the slope's covering soil is 93 cm, the thickness of the step's covering soil is 96 cm, and the thickness of the bottom layer of covering soil is 95 cm.

Embodiment 3

[0033] First pour the covering soil from the top layer to the next step, the thickness of the covering soil is 100cm, then clean up the stones on each layer of slope and steps in turn, level the slope and the covering soil on the steps, and finally roll the stones on the bottom step 8 Second, level the soil.

[0034] Using the method of the present invention to cover the soil, after 7 days of scouring and settlement, the thickness of the slope's covering soil is 92 cm, the thickness of the step's covering soil is 98 cm, and the thickness of the bottom layer of covering soil is 98 cm.

Abstract

The invention belongs to the technical field of mine restoration, discloses a mine restoration stair step soil covering method, and aims to solve the problem of difficulty in stair step soil covering in existing mine restoration. The method comprises the following steps that: (1) covering soil is poured to stair steps of a mine in sequence from a top layer; (2) stones on each layer of slope surface and steps are sequentially cleaned from the top layer, and the covering soil on the slope surfaces and the steps is leveled; and (3) the stones on the bottom-most step are subjected to layered rolling, and the covering soil is leveled. According to the invention, the stair steps of a mine can be safely and effectively covered with soil, the slope surfaces and the steps after soil covering are stable, and plants grow well.

Description

technical field [0001] The invention belongs to the technical field of mine restoration, and in particular relates to a soil covering method for steps of mine restoration. Background technique [0002] Mineral resources, as one of the very important energy sources, are closely related to the development of social economy and the use of mineral energy. In 2018, among the 40 kinds of mineral resources in the global statistics, my country ranked first in the consumption of 30 kinds of mineral resources in the world, and it is worthy of the name of the world's largest producer and trader of mineral resources. The vigorous development of mineral resources has accelerated the economic development of our country, but at the same time it has also affected the ecological environment. As of 2018, there are about 99,000 abandoned mines of various types in my country. According to mining methods, there are 80,600 abandoned mines for open-pit mining, 16,400 abandoned mines for undergrou...
