Description

Technical Field

[0001] This invention relates to the field of mine ventilation, and in particular to a mobile dust blocking system for long-distance single-heading roadways. Background Technology

[0002] Blasting is a common method for developing roadways in mines. This method often generates a lot of dust. Mine safety regulations stipulate that after blasting at the working face, forced ventilation must be carried out for a certain period of time to eliminate the dust generated by the blasting and purify the working environment near the working face.

[0003] However, due to the spread of dust, the prescribed forced ventilation time often cannot completely remove the dust, leaving residues. This can lead to a risk of dust-related occupational health diseases for workers who enter the vicinity of the working face after the dust is extracted. This can harm the physical and mental health of workers and increase additional economic costs for enterprises. Therefore, we provide a mobile long-distance single-heading roadway working face.

[0051] The distance from the first ventilation duct to the working face 1 is the safe distance for blasting operations, ensuring that the first ventilation duct is not damaged by the blast shock wave after blasting. The mine exhaust fan is positioned on the left side of the roadway wall of the first ventilation duct, horizontally in front of the mine exhaust fan, at the same safe distance from the working face 1, to ensure that the mine exhaust fan is not damaged by the blast shock wave after blasting. The mine exhaust fan begins operation after the blast at the working face, drawing the toxic and harmful gases produced by the blast into the second ventilation duct, from which they are then discharged to a dedicated return air roadway.

[0052] The airflow baffle 403 blocks the gaps outside the barrier to prevent dust generated after blasting from spreading into the tunnel through the gaps. The airflow baffle 403 can extend and retract. When the mobile dust blocking device 4 reaches the designated position, the outer airflow baffle 40, along with the inner airflow baffle 40, extends according to the width of the tunnel cross section until both ends of the outer airflow baffle 40 contact the tunnel wall. After that, the inner airflow baffle 40 detaches from the outer airflow baffle 40 and extends downward to contact the ground, blocking the gaps outside the barrier.

[0053] The first infrared ranging sensor 404 and the second infrared ranging sensor 405 detect the distance between the airflow baffle 403 and the two sides of the roadway, thereby controlling the airflow baffle 403 to automatically extend to a suitable position after the mobile dust blocking device 4 reaches the designated location; the first dust detector 406 detects the dust concentration in the roadway after the mobile dust blocking device 4 reaches the designated position. If dust is detected, it automatically controls the barrier generator 418 to start, and then controls the strength of the barrier generated by the barrier generator 418 according to the detected dust concentration; the second dust detector 407 detects the screen The dust concentration behind the barrier is fed back to the control center 417, which automatically increases or decreases the barrier's strength to block dust diffusion and save energy. The vision sensor 408 captures visual information, including environmental images and wayfinding markers. The environmental images are transmitted via the control center 417 to the information display screen 53 on the barrier controller 5, allowing personnel to understand the environment in which the mobile dust barrier 4 is located. Wayfinding markers are placed on the roadway floor; the vision sensor 408 identifies these markers and adjusts the barrier strength accordingly. The device controller 5 is set at a location where it automatically travels to the working face to be blasted. The first ultrasonic sensor 409, second ultrasonic sensor 410, third ultrasonic sensor 411, fourth ultrasonic sensor 412, fifth ultrasonic sensor 413, sixth ultrasonic sensor 414, seventh ultrasonic sensor 415, and eighth ultrasonic sensor 416 are arranged on the side of the platform 402. Their function is to detect obstacles appearing on the guide marks around the mobile dust blocker 4, thereby replanning the automatic travel path. The first ultrasonic sensor 409 and the seventh ultrasonic sensor 415 work together to detect obstacles to the left front of the mobile fourth dust detector; the fifth ultrasonic sensor 413 and the eighth ultrasonic sensor 416 work together to detect obstacles to the left rear of the mobile fourth dust detector; the second ultrasonic sensor 410 and the third ultrasonic sensor 411 work together to detect obstacles to the right front of the mobile fourth dust detector; and the fourth ultrasonic sensor 412 and the sixth ultrasonic sensor 414 work together to detect obstacles to the right rear of the mobile fourth dust detector.
