The plurality of blocking rods 22 are connected end to end through the connecting flanges 23. By increasing and decreasing the number of blocking rods 22, the overall length of the lateral blocking column 21 can be adjusted. The connection flanges 23 between the multiple lateral blocking columns 21 are staggered to avoid the connection flanges 23 being concentrated in one place, which would cause the reliability of the local structure to be too low, thereby improving the reliability of the overall structure.

The first arc rod 36 and the second arc rod 37 cross each other, so that the first arc rod 36 and the second arc rod 37 can support each other, which plays a role in improving the reliability of the structure. The cross-arranged first arc rod 36 and the second arc rod 37 can provide support force to the mine in different directions, thereby improving the stability of the mine. A plurality of cross top nets are provided, and the plurality of cross top nets are evenly arranged along the length direction of the connecting plate 31, and the two ends of the first arc rod 36 are respectively fixed to the adjacent second arc rod 37. The two ends of the first arc rod 36 are respectively fixed to the second arc rod 37 in the adjacent cross top nets at the two ends, and the two ends of the second arc rod 37 are fixed to the first arc rod 36 in the adjacent cross top nets at the two ends, thereby improving the structural stability between the adjacent cross top nets, so that the cross top net can stably support the top of the mine.

[0043] The top frame also includes a top stop column 38, which extends along the length direction of the connecting plate 31, and is provided through a plurality of first arc rods 36 and second arc rods 37. The top stop column 38 is fixedly connected to the plurality of first arc rods 36 and second arc rods 37 respectively. The first arc rods 36 and second arc rods 37 are connected by the top stop column 38, and the first arc rods 36 and second arc rods 37 are supported by the top stop column 38, so as to improve the structural stability of the top frame. The top stop can also provide support force for the top of the mine, further improving the stability of the mine.

The top mesh cover 39 blocks the gravel on the top of the mine, thereby reducing the gravel that falls into the working space 42.

[0044] The partition 34 is provided with a through slot 35, which is arranged at the connection seat 12. The column 11 is fixedly connected with a ladder 17. The arrangement of the ladder 17 facilitates entering the positive pressure space 41 through the through slot 35.

[0045] The column 11 is fixedly installed with an oxygen sensor 52, a liquid level sensor 53 and an alarm. When the oxygen sensor 52 detects that the oxygen concentration is low or the liquid level sensor 53 detects that the liquid level is high, an alarm is sounded through the alarm to realize the alarm function. The control module 51 is electrically connected to the oxygen sensor 52, the liquid level sensor 53 and the alarm respectively. In this embodiment, the control module 51 is an MCU. The alarm includes an oxygen alarm light 54, a liquid level alarm light 55 and an alarm horn 56. The oxygen alarm light 54 and the liquid level alarm light 55 emit light, and the alarm horn 56 emits sound, realizing the function of sending an alarm through the alarm. The oxygen sensor 52 is used to detect the oxygen concentration in the working space 42. When the oxygen concentration in the working space 42 is low, the oxygen sensor 52 sends an oxygen detection signal to the control module 51. The control module 51 controls the oxygen alarm light 54 to emit light and controls the alarm horn 56 to emit sound according to a preset program. The liquid level sensor 53 is used to detect the liquid level. When the water level in the working space 42 reaches the liquid level sensor 53, the liquid level sensor 53 sends a liquid level detection signal to the control module 51. The control module 51 controls the liquid level alarm light 55 to light up and controls the alarm speaker 56 to sound according to a preset program, thereby realizing the function of automatically sending an alarm.

[0046] The two side baffle frames and the top frame support the side wall and the top of the mine respectively, which can support the mine and improve the reliability of the mine. The fan blows air into the positive pressure space 41, and a certain positive pressure is generated in the positive pressure space 41. The air in the positive pressure space 41 enters the working space 42 through the through groove 35, and then is discharged to the outside of the mine through the working space 42, which promotes the air circulation in the mine and ensures that there is sufficient oxygen in the mine.

[0047] This embodiment has the following advantages:

[0048] Ore transportation and excavation operations can be carried out in the working space 42. If water flows into the mine during the operation, personnel can enter the higher positive pressure space 41 through the through groove 35, and the water will flow downward into the working space 42. Personnel can move to a safe area through the positive pressure space 41, avoiding the obstruction of water flow to the escape of personnel, preventing personnel from choking on water, improving safety, and achieving the advantage of making it easier for personnel to evacuate from danger.

[0049] If a fire occurs in the working space 42 during the operation, personnel can enter the positive pressure space 41 through the through slot 35. The partition 34 is made of heat-insulating material, and the high-temperature gas in the working space 42 is blocked by the partition 34 to prevent personnel from being burned when evacuating through the positive pressure space 41. At the same time, the air in the positive pressure space 41 has a certain positive pressure, thereby preventing the smoke in the working space 42 from entering the positive pressure space 41 through the through slot 35. Even if smoke accidentally enters the positive pressure space 41, the air in the positive pressure space 41 can drive the smoke to be quickly discharged into the working space 42 during the flow of air to the working space 42, thereby improving safety and achieving the advantage of making it easier for personnel to evacuate from danger.

[0050] The connecting seat 12 and the column 11 are fixed by inserting the pile rod 13 into the side wall of the mine, so that the connecting seat 12 can stably support the top frame, ensure the structural stability of the top frame, and enable the top frame to stably support the top of the mine. The pile rod 13 inserted into the side wall of the mine can support the mine and prevent the side wall of the mine from collapsing.

[0051] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the invention should also fall within the scope of protection of the claims of the present invention.
