TECHNICAL FIELD
[0001] The utility model relates to the field of mine exploration, and concretely relates to a depth measuring device for mine goaf exploration. BACKGROUND
[0002] With the rapid development of China's economy, the demand for mineral resources increases year by year, and the mining scale is expanding. In the process of mining, the formation of goaf is inevitable. Goaf refers to the space left after underground mineral resources are mined out. Its existence seriously threatens the safety of mine production and the ecological environment of the ground. In order to ensure the safety of mine production and the safety of ground buildings, it is of great significance to explore, monitor and manage goaf.
[0003] For example, the Chinese utility model patent with the patent publication number CN222895714U can effectively explore goaf of different depths by setting a turntable and a connecting assembly, and the stability is improved. The problem of inconvenient storage of the existing goaf depth measuring device is solved by adjusting the installation angle of the mounting seat. However, in actual use, the connecting assembly can only restrict one side from rotating, and the cable itself has a certain extensibility. When the cable is descending, the tension is insufficient, and the bending amplitude is not obvious when measuring shallow depth. When the depth gradually increases, the restraining force will decrease accordingly, which has certain disadvantages. In view of this, we propose a depth measuring device for mine goaf exploration.
