Coal mine underground gas outburst elimination drill hole coal pit peeping device and method based on laser

The invention discloses a laser-based coal mine underground gas outburst elimination drill hole coal pit peeping device and method. The laser-based coal mine underground gas outburst elimination drill hole coal pit peeping device comprises a data receiving and processing unit, a pushing rod and a measuring probe, the measuring probe comprises a mounting cylinder, a first laser distance measuring sensor, a second laser distance measuring sensor, a first motor, a second motor, a camera and an attitude sensor; and the lower part of the mounting cylinder is coaxially connected with the upper end of the pushing rod through a transition connecting piece. The device is high in automation degree, reduces manual operation, and effectively reduces measurement errors. The measurement data is processed to obtain the position, attitude, form, volume and other parameters of the coal pit space, and the three-dimensional model of the coal pit is obtained at the same time. Reliable technical support is provided for evaluation
