The present disclosure relates to a soil cover and irrigation method for an open-pit mine
dump, and specifically to an open-pit mine dump for near-surface soil sequence reconstruction
and a deep water replenishing method thereof
Reclamation of open-pit mine dumps is very important for the environmental governance of
the mining area. For a long time, due to the serious development of soil fissures and rapid water
infiltration after subsoil layer reconstruction in the dump, it is difficult to preserve water
resources in shallow soils. On the other hand, the water capillary action in deep soils is limited,
making it difficult to replenish water to the surface and difficult for surface plants to absorb
water from soil. Especially in the case of less precipitation in northern China, the reclamation
effect is poor, which needs to be solved urgently.
Drip irrigation is one of the most water-saving irrigation technologies for farmland
irrigation so far. It can effectively reduce the ineffective evaporation of soil water, avoid water
runoff, and can easily control the precise watering depth. However, conventional drip irrigation
systems are arranged near the surface and are easily affected by field operation equipment and
cold weather in winter, so the effective service time of such systems is short. In addition, in order
to avoid the damage to the plastic dripping pipeline caused by the severe cold in winter, it is
necessary to carry out the pipeline laying and collection and storage work once a year, which is
not only labor-intensive, but also accelerates the damage of equipment.
To solve the problems in the above-mentioned prior art, the present disclosure provides an
open-pit mine dump for near-surface soil sequence reconstruction and a deep water replenishing method thereof, where the soil sequence is reconstructed and drip irrigation pipelines are arranged inside the open-pit mine dump, to replenish water for the reclaimed soil of the dump, thereby improving the utilization of irrigation water while avoiding system damage.
To achieve the above objective, the present disclosure adopts the following technical
solutions. A method for near-surface soil sequence reconstruction in an open-pit mine dump
includes: laying a water blocking layer on a dump bottom layer, constructing a water storage and
replenishing layer on the water blocking layer, arranging peak-shaped infiltration zones at
intervals of 100-200 m on an upper surface of the water storage and replenishing layer, so that
peaks of the infiltration zones are exposed out of a surface of the open-pit mine dump, laying a
stripped material such as less and sand on the water storage and replenishing layer as a subsoil
layer, and laying stripped topsoil on the subsoil layer as a planting layer;
arranging water replenishing pipes crossed in an # shape at a position 1 m above a bottom
of the water storage and replenishing layer, symmetrically forming through holes having a
diameter of 1 mm at intervals of 30 cm on a surface of each of the water replenishing pipes,
where the water replenishing pipes are intermittently arranged at a position in the water storage
and replenishing layer corresponding to the infiltration zones, the water replenishing pipes within
a range of every 200-400 m 2 are connected to a water delivery pipe, and the water delivery pipe
is connected to a high-pressure water pump (pipe) and a high-pressure air pump (pipe) after the
water delivery pipe is arranged vertically with a top end thereof exposed out of the surface of the
open-pit mine dump;
using a range of 200-400 m 2 corresponding to each water delivery pipe as a monitoring unit,
and within each monitoring unit, arranging a sixth sensor, a fourth sensor, a second sensor, a
third sensor, and a fifth sensor respectively at a junction between the water blocking layer and
the water storage and replenishing layer, a junction between the water storage and replenishing
layer and the subsoil layer, a junction between the subsoil layer and the planting layer, a middle
portion of the subsoil layer, and a middle portion of the water storage and replenishing layer;
installing a vertical infiltration channel in the water blocking layer in each monitoring unit,
where a top portion of the infiltration channel is 1-2 m above the upper surface of the water
storage and replenishing layer, an on-off valve is installed inside the infiltration channel, and the on-off valve, the high-pressure water pump, the high-pressure air pump, the second sensor, the third sensor, the fourth sensor, the fifth sensor, and the sixth sensor are connected to a controller; and laying an evaporation retardation layer on the planting layer and the infiltration zones, where a height of a top surface of the evaporation retardation layer is level with heights of the peaks of the infiltration zones; each of the infiltration zones is formed by stacking stones with a particle size of 1 cm or more, a top width of each of the infiltration zones is 1-3 m, and a thickness of the subsoil layer is adjusted, so that the evaporation retardation layer is raised from each of the infiltration zones toward two sides thereof, with a slope gradient rate of 5%o; the water blocking layer is constructed by wetting and pressurized solidification of a stripped material such as clay and mudstone of an open-pit mine, and has a thickness of not less than 2.0 m; and the water storage and replenishing layer is constructed of sand particles with a particle size of 1-2 mm, and has a thickness of 0.3-0.5 m.
Further, when a thickness of the planting layer is greater than 0.3 m, a first sensor is
arranged in a middle portion of the planting layer, and the first sensor is connected to the
controller.
Further, the planting layer has a thickness of 0.5-1 m when grass is planted in the planting
layer; the planting layer has a thickness of 1-3 m when shrubs or small trees are planted in the
planting layer; and the planting layer has a thickness of 3-5 m when large trees are planted in the
planting layer.
A deep water replenishing method of the open-pit mine dump for near-surface soil sequence
reconstruction includes the following steps:
when data of the first sensor and the second sensor shows that water is sufficient, the
controller operating in a standby state;
when the data of the first sensor and the second sensor shows a mild water shortage and the
other sensors show that water is sufficient, controlling, by the controller, the high-pressure air
pump to operate to drive the water to move upward with air, so as to replenish water to the planting layer; when the data of the first sensor and the second sensor shows a moderate water shortage, data of the third sensor and the fourth sensor shows a mild water shortage, and data of the fifth sensor and the sixth sensor shows that water is sufficient, controlling, by the controller, the high-pressure water pump to inject water into the water storage and replenishing layer, and after the water injection is completed, controlling, by the controller, the high-pressure air pump to operate to drive the water to move upward with air, so as to replenish water to the planting layer; when data of all the sensors shows different degrees of water shortage, controlling, by the controller, the high-pressure water pump to operate to inject water into the water storage and replenishing layer, and after the water injection is completed, controlling, by the controller, the high-pressure air pump to operate to drive the water to move upward with air, so as to replenish water to the planting layer; meanwhile, artificially watering plants on ground; and if the data of the fifth sensor and the sixth sensor still shows different degrees of water shortage after the planting layer is replenished with water, determining that the water blocking layer in the monitoring unit is damaged and needs to be repaired; and when the data of the first sensor, the second sensor, and the third sensor shows that water is sufficient, and the data of the fourth sensor, the fifth sensor, and the sixth sensor shows that water is excessive, which indicates that excessive water is accumulated in the water storage and replenishing layer, controlling, by the controller, the on-off valve to open, to quickly drain the excessive water accumulated in the water storage and replenishing layer down through the infiltration channel.
Compared with the prior art, according to the present disclosure, the soil sequence of the
dump is reconstructed, to provide a foundation for long-time retention of water in the soil, so as
to provide water support for vegetation growth. Water is directly and accurately replenished into
the soil in a mode similar to drip irrigation, thereby improving the utilization of water resources,
improving the water replenishing effect, and conserving water resources. The water body is
driven by high-pressure air to rise, to reduce the use of water resources. Water replenishing or air
supply is dynamically controlled through analysis of the sensors, to improve the system
utilization rate and accuracy and achieve remote unmanned operation.

The present disclosure is further described below with reference to the accompanying
drawings.
The technical solutions in the embodiments of the present disclosure will be described
clearly and fully with reference to the accompanying drawings in the embodiments of the present
disclosure. Apparently, the embodiments described are merely some embodiments, rather than all
of the embodiments of the present disclosure. All other embodiments obtained by those of
ordinary skill in the art without creative efforts based on the embodiments of the present
disclosure shall fall within the protection scope of the present disclosure.
The present disclosure provides a technical solution. As shown in FIG. 1, a water blocking
layer 2 is laid on a dump bottom layer 1. The water blocking layer 2 is constructed by wetting
and pressurized solidification of a stripped material such as clay and mudstone of an open-pit
mine. The water blocking layer 2 has a thickness of not less than 2 m. The water blocking layer 2
partially blocks the upward or downward infiltration channels of water and hinders the upward
or downward infiltration of water to a certain extent, which can slow down the upward or
downward infiltration of water through the water blocking layer. Therefore, on the one hand, the
residence time of water above the water blocking layer in the soil can be increased, thereby increasing the moisture content in the near-surface soil. On the other hand, when the upper layers are dry, water in the lower layers can infiltrate into the upper layer soil through the water blocking layer 2 under the capillary action, so as to provide necessary water for the growth of vegetation.
A water storage and replenishing layer 3 having a thickness of 0.3-0.5 m is constructed on
the water blocking layer 2 using sand particles with a particle size of 1-2 mm. Peak-shaped
infiltration zones 4 are arranged at intervals of 100-200 m on an upper surface of the water
storage and replenishing layer 3. Each of the infiltration zones 4 is formed by stacking stones
with a particle size of 1 cm or more, and has a top width of 1-3 m and a bottom width of 50 m.
Peaks of the infiltration zones 4 are exposed out of a surface of the dump. The width by which
each of the infiltration zones 4 is exposed out of the surface of the dump does not exceed 10 m.
In this way, when the atmospheric precipitation is large, the surface runoff can directly infiltrate
into the water storage and replenishing layer 3 through the infiltration zones 4. Due to the high
porosity and good water stability, the water storage and replenishing layer 3 allows water to be
quickly and evenly distributed in the entire layer, so as to achieve uniform water replenishment
to the soil. In addition, the infiltration of water from the bottom to the top can improve the soil
wetting effect and reduce evaporation.
A 3-5 m thick layer of stripped material from the open-pit mine is laid on the water storage
and replenishing layer 3 as a subsoil layer 5. The material selected is not easy to disintegrate
when exposed to water, has a certain porosity to realize the slow infiltration of water, and has a
strong capillary function. Soil is laid on the subsoil layer 5 as a planting layer 6 according to the
supply conditions, the requirements of the vegetation to be planted, the freezing depth in winter,
etc. The planting layer 6 has a thickness of 0.5-1 m when grass is planted in the planting layer;
the planting layer 6 has a thickness of 1-3 m when shrubs or small trees are planted in the
planting layer; and the planting layer 6 has a thickness of 3-5 m when large trees are planted in
the planting layer.
For arid and semi-arid regions, in order to reduce near-surface soil moisture evaporation, as
shown in FIG. 3, a 1-2 cm thick layer of gravels is laid on the planting layer 6 and the infiltration
zones 4 as an evaporation retardation layer 7, the gravels have a diameter of about 1 cm, and a height of a top surface of the evaporation retardation layer 7 is level with heights of the peaks of the infiltration zones 4. A thickness of the subsoil layer 5 is adjusted, so that the evaporation retardation layer 7 is raised from each of the infiltration zones 4 toward two sides thereof, with a slope gradient rate of 5%o. This layer also has a function of blocking soil heat conduction to maintain soil temperature in winter and block deep soil heating in summer, thereby protecting plant roots. For wet areas with heavy rainfall, this layer may be omitted.
Corrosion and pressure resistant pipes crossed in an # shape are arranged at a position 1 m
above a bottom of the water storage and replenishing layer 3 as water replenishing pipes 8, and
through holes are formed at intervals of 30 cm on a surface of each of the water replenishing
pipes 8. The water replenishing pipes 8 are arranged throughout the water storage and
replenishing layer 3, and are intermittently arranged at a position in the water storage and
replenishing layer 3 corresponding to the infiltration zones 4. As shown in FIG. 2, the water
replenishing pipes 8 within a range of every 200-400 m 2 are connected to a water delivery pipe 9.
The water delivery pipe 9 is connected to a high-pressure water pump 10 and a high-pressure air
pump 11 after the water delivery pipe 9 is arranged vertically with a top end thereof exposed out
of the surface of the dump. The high-pressure water pump 10 and the high-pressure air pump 11
can inject water and supply air to the water delivery pipe 9.
A range of 200-400 m 2 corresponding to each water delivery pipe 9 is used as a monitoring
unit. Within each monitoring unit, a sixth sensor 17, a fourth sensor 15, a second sensor 13, a
third sensor 14, and a fifth sensor 16 are respectively arranged at a junction between the water
blocking layer 2 and the water storage and replenishing layer 3, a junction between the water
storage and replenishing layer 3 and the subsoil layer 5, a junction between the subsoil layer 5
and the planting layer 6, a middle portion of the subsoil layer 5, and a middle portion of the
water storage and replenishing layer 3. A vertical stainless steel pipe is installed in the water
blocking layer 2 in each monitoring unit as an infiltration channel 18. Through holes are
provided on a wall of the infiltration channel 18. A top portion of the infiltration channel 18 is
1-2 m above the upper surface of the water storage and replenishing layer 3. An on-off valve is
installed inside the infiltration channel 18. The on-off valve, the high-pressure water pump 10,
the high-pressure air pump 11, the second sensor 13, the third sensor 14, the fourth sensor 15, the fifth sensor 16, and the sixth sensor 17 are connected to a controller. When a thickness of the planting layer 6 is greater than 0.3 m, a first sensor 12 is arranged in a middle portion of the planting layer 6, and the first sensor 12 is connected to the controller.
Data displayed on each sensor can represent one of four states: excessive water, sufficient
water, mild water shortage, and moderate water shortage. The controller receives data of the
sensors and controls operational states of an on-off valve, the high-pressure water pump 10, and
the high-pressure air pump 11 according to the data of the different sensors, to achieve deep
water replenishment. Each monitoring unit operates independently of each other.
When data of the first sensor 12 and the second sensor 13 shows that water is sufficient,
which indicates that current conditions are suitable for vegetation growth, the controller operates
in a standby state. When the data of the first sensor 12 and the second sensor 13 shows a mild
water shortage and the other sensors show that water is sufficient, the controller controls the
high-pressure air pump 11 to operate, and the high-pressure air pump 11 blows high-pressure air
into the water storage and replenishing layer 3 through the water delivery pipe 9 and the water
replenishing pipes 8, to drive the water to move upward with air, so as to replenish water to the
planting layer 6.
When the data of the first sensor 12 and the second sensor 13 shows a moderate water
shortage, data of the third sensor 14 and the fourth sensor 15 shows a mild water shortage, and
data of the fifth sensor 16 and the sixth sensor 17 shows that water is sufficient, the controller
controls the high-pressure water pump 10 to operate, and the high-pressure water pump 10
injects water into the water storage and replenishing layer 3 through the water delivery pipe 9
and the water replenishing pipes 8. After the water injection is completed, the controller controls
the high-pressure air pump 11 to operate, and the high-pressure air pump 11 blows high-pressure
air into the water storage and replenishing layer 3 through the water delivery pipe 9 and the
water replenishing pipes 8, to drive the water to move upward with air, so as to replenish water
to the planting layer 6.
When data of all the sensors shows different degrees of water shortage, the controller
controls the high-pressure water pump 10 to operate to inject water into the water storage and
replenishing layer 3, and after the water injection is completed, the controller controls the high-pressure air pump 11 to blow high-pressure air into the water storage and replenishing layer
3 through the water delivery pipe 9 and the water replenishing pipes 8, to drive the water to
move upward with air, so as to replenish water to the planting layer 6. Meanwhile, plants on
ground are artificially watered. If the data of the fifth sensor 16 and the sixth sensor 17 still
shows different degrees of water shortage after the planting layer 6 is replenished with water, it is
determined that the water blocking layer 2 in the monitoring unit is damaged and needs to be
repaired.
When the data of the first sensor 12, the second sensor 13, and the third sensor 14 shows
that water is sufficient, and the data of the fourth sensor 15, the fifth sensor 16, and the sixth
sensor 17 shows that water is excessive, which indicates that excessive water is accumulated in
the water storage and replenishing layer 3, the controller controls the on-off valve to open, to
quickly drain the excessive water accumulated in the water storage and replenishing layer 3
down through the infiltration channel 18, thereby reducing the amount of water in the water
storage and replenishing layer 3.
It will be apparent to those skilled in the art that the present disclosure is not limited to the
details of the above-described exemplary embodiments, and the present disclosure may be
embodied in other specific forms without departing from the spirit or essential characteristics of
the present disclosure. Therefore, the embodiments are to be regarded in all respects as
