[0002] The chute is the main channel for transporting ore during mining, and plays a vital role in improving production efficiency and saving mining costs. The difficulty of measuring the height of deep hole chutes in mines lies in: the measurement distance is long, and the height of deep hole chutes is generally around 200-300 meters. Commonly used industrial level meters such as radar, ultrasonic, and heavy hammers are difficult to meet their measurement conditions; the dust concentration is high when ore is placed at the bottom of the chute or when the ore is lowered from the wellhead, which affects the measurement accuracy; the diameter of the chute reaches 10-20m, and it is difficult to install and repair the measuring instrument, and it is difficult to ensure the personal safety of the measurement personnel; the working ground around the mine chute mouth is uneven and changes at any time with the mining surface of the mine. The measuring device needs to be moved at any time, and the fixed measuring device is difficult to meet its measurement requirements; the climate environment of the open-pit mining chute in the mine is relatively harsh, and the ambient temperature in winter even reaches below minus 20°. In some periods, the open-air wind speed reaches 5-6 levels. At the same time, rain and snow and other weather have high requirements on the long-term temperature resistance, protection level and other technical performance of the instrument and the firmness of the measurement value device.
