Description

Technical Field

[0001] The invention relates to the field of coal mining equipment, in particular to an automatic cleaning drilling peek device. Background Art

[0002] With the continuous development of coal mining technology, the proportion of deep-buried coal seams in my country's coal mining is increasing. After entering deep mining, the geological structure is complex and the stress state of the surrounding rock is complex and changeable, resulting in large deformation of the coal-rock roadway, which is prone to roof collapse, coal wall slabs and bottom bulging. This brings great difficulties to the stability control of the surrounding rock of deep well roadways, and also restricts the safe and efficient production of coal mines. In response to this problem, domestic and foreign scholars have done a lot of research on the stability support of coal-rock roadways under high stress conditions in deep wells. At present, they mainly use borehole imaging instruments to observe the surrounding rock failure structure of coal roadways under high stress in deep wells, analyze the failure mechanism and propose reasonable surrounding rock control measures. Combined with theoretical calculation methods, a roadway support parameter optimization scheme is proposed to provide a reference for surrounding rock control in similar coal mines.

[0003] When the commonly used borehole detection device detects the borehole, the camera on the probe rod is often affected by the rock debris in the borehole, which reduces the clarity of the observed and recorded image. Especially in coal holes, even if the borehole is flushed with water, the coal dust can still easily block the camera in the probe rod, thereby reducing the clarity of the observed and recorded image and affecting the detection results. Therefore, there is an urgent need for a borehole peep device that can automatically clean the coal dust impurities on the camera during the detection process. Summary of the invention
