[0002] At present, there is unmined coal in the rock layer below the slope of open-pit coal mines in my country, which has a certain tendency to spontaneously combust. It spontaneously combusts under long-term oxidation, causing the surface soil temperature in local areas of the slope to rise, and harmful gases will be released during combustion. According to investigations, after ecological restoration of some open-pit mines, the areas where residual coal spontaneously combust underground cause the surface soil temperature to rise, leading to plant death, and also increasing the difficulty of subsequent ecological restoration in this area, causing serious impact on the overall ecological restoration plan. Therefore, there is an urgent need for a device that simulates on-site environmental conditions, accurately and realistically simulates the on-site environment, and proposes a method for screening pioneer plants in the spontaneous combustion zone of the coal body, and screens out pioneer plants that can grow at different high temperatures under the operating conditions of this device.

[0005] A base and support plates on both sides are arranged in the dust cleaning area. A plurality of rollers arranged in parallel are arranged on the base. The rollers jointly support the dust box, and the dust box is pulled out from one side or the opposite side of the shell.

[0006] The top of the support plate extends into the transition cleaning area and supports the wire filter through a weight sensor, and the wire filter is located on the lower surface of the raw coal area; a support frame is fixedly connected in the middle of the support plate, and a vibration motor is symmetrically arranged on the support frame. The top of the vibration motor is connected to the bottom end of the vibration sensor rod, and the vibration sensor rods on the left and right sides pass through the wire filter and the top ends are connected to each other.

[0007] The automatic coal replenishment device includes a coal storage hopper, a cylindrical cavity, a rotating shaft, a motor and a sliding bucket; the cylindrical cavity is located between the coal storage hopper and the sliding bucket, a rotating shaft is provided in the cylindrical cavity, a plurality of rotating blades are provided on the outer circumference of the rotating shaft, the outer edges of the rotating blades are close to the inner surface of the cylindrical cavity, and the end of the sliding bucket is connected to the feeding port; the outer end of the rotating shaft extends out of the cylindrical cavity and is connected to the blade motor.

[0008] The automatic blowing control device includes a compressed air pipeline, an electric control valve, an air source and an air source controller. One end of the compressed air pipeline is connected to the air source, and the other end is connected to the inlet end of the electric control valve. The control end of the electric control valve is connected to the air source controller, and the outlet end of the electric control valve is connected to the feeding port through a high-pressure air duct.

[0009] A partition is arranged between the raw coal area and the covered soil area, and the partition is composed of a mixture of thin mud and straw with a certain length.

[0010] The spray device includes a water pump, a water pipe, a water reservoir, a solenoid valve, a nozzle and a water source controller; the nozzle is arranged on the top of the shell, the nozzle is connected to the water reservoir through the solenoid valve on the pipeline, and the control end of the solenoid valve is connected to the data processing system in the intelligent environment monitoring and visualization area through the water source controller, and the top of the water reservoir is connected to the water pump through the water pipe.

[0012] The test plants used were Zoysia japonica, Zoysia japonica and Zoysia tenuifolia.

[0013] The plant screening method of the pioneer plant screening device in the spontaneous combustion zone of the coal body on the slope of the open-pit coal mine comprises the following steps: 1) Before the device starts working, the maximum and minimum critical values ​​of the gravity sensor are set through the discharge controller, and the maximum and minimum critical values ​​of humidity and temperature are set through the data processing system; 2) Ignite the coal through the feeding port, turn on the power, and the intelligent environmental monitoring and visualization device and the gravity sensor start working. As the coal in the coal seam burns, when the weight of the coal seam sensed by the weight sensor decreases to the minimum critical value, the discharge controller controls the vibration motor to start vibrating, and the coal ash in the coal seam falls into the ash box due to the vibration. The ash box can be pulled out from both sides along the shaft wheel to clean the coal ash in the ash box. At the same time, when the weight of the coal seam sensed by the weight sensor decreases to the minimum critical value, the discharge controller turns on the blade motor in the automatic coal replenishment device, and the blade motor drives the rotating shaft in the storage hopper to rotate, and the coal falls from the storage hopper into the original coal seam to achieve automatic replenishment of the coal. As the coal is replenished, the weight of the coal seam sensed by the weight sensor will increase. When it reaches the maximum critical value, the discharge controller turns off the vibration motor and the blade motor, and the ash shaking device and the automatic coal replenishment device stop working; 3) Due to the combustion of coal, the temperature of the monitoring point in the planting area of ​​the covered soil area shows a trend of first rising and then falling, and the trend is repeated. When the temperature displayed by the thermal imager in the intelligent environment monitoring and visualization area is lower than the critical value, the wind source controller controls the electric control valve in the automatic blowing device to open. At this time, the compressed air pipeline is connected, so that the compressed gas can be ejected from the high-pressure air duct, further igniting the coal, so that the temperature of the monitoring point in the planting area increases; 4) When the detected temperature is higher than the critical temperature, the air source controller controls the solenoid valve to close and the compressed air pipeline to close. When the humidity sensor in the intelligent environment monitoring and visualization area detects that the humidity in the overall device is lower than the set humidity required for the experiment, the water source controller opens the solenoid valve and the spray device starts working. When the humidity detected by the humidity sensor is higher than the set maximum value, the controller controls the solenoid valve to close and the spray device stops working; 5) The high-definition camera transmits the growth status of plants in the planting area in real time through the display screen; 6) The automation device set in this system operates through repeated cycles of coal combustion. The pioneer plant screening device for spontaneous combustion zone of coal body on the slope of an open-pit coal mine of the present application adopts the above structure, which has the following beneficial effects: High soil temperature has always been an important factor restricting the ecological restoration of mines. So far, there are few studies in China on laboratory simulation of high soil temperature caused by coal bodies on slopes, and the simulation equipment is not perfect. This device brings laboratory conditions infinitely close to field conditions, improves the conversion rate of scientific and technological achievements, and is one step closer to the research on ecological restoration of high ground temperature soil on slopes. Due to the diffusion of heat, the soil temperature in each area is different. The present invention can screen out plants that grow well under different temperature gradients, expand the research scope, and provide ideas for ecological restoration in high-temperature areas in the future. The present invention can control the laying thickness of the supplementary raw coal area to control the temperature of the monitoring center and the surrounding area, and can more completely simulate the ignition area with different residual coal contents, thereby improving the integrity and convenience of the research; 4. The screening method of the present invention is the first to apply warm-season Zoysia japonica to the high geothermal ecological restoration area on the mine slope, which is of great significance and has significant effects.
