Abstract

The invention discloses a mining roadway rock stratum displacement monitoring device for underground engineering. The device comprises a mounting plate mounted on the top wall of a roadway; a measuring mechanism is mounted at the lower end of the mounting plate; two detection grooves are symmetrically formed in the side wall of the roadway; a balance mechanism is jointly mounted in each detectiongroove and at the bottom of the roadway; and the measuring mechanism comprises a measuring box. According to the device of the invention, the comprehensiveness of detection is improved through the twobalance mechanisms; the balance mechanisms and the measuring mechanism are connected through a rope so as to perform detection; high-precision equipment is more suitable for a roadway environment andcarrying out real-time monitoring; the horizontal placement of the measuring box is realized through adjusting screws; the balance of the measuring box is achieved through weight balancing columns; the long-term use of the device is facilitated; the balance mechanisms, the rope and a double-wheel-groove mechanical structure perform transmission outside the measuring box, and a feedback disc, a light sensor and light emitters are located in the measuring box, and therefore, the interference of the outside on measurement is reduced, and measurement accuracy is improved.

Description

technical field [0001] The invention relates to the field of underground engineering safety, in particular to a displacement monitoring device for mining tunnel rock formations used in underground engineering. Background technique [0002] In my country, coal mine resources are abundant, and the mining and use of coal mines provide most of the power supply. In the process of coal mining, it is necessary to drill wells and dig coal mine roadways first. The firmness of the roadways is related to the life safety of mining personnel. Therefore, measurement The rock displacement measurement device monitors the dynamics of the rock strata in real time to ensure the safety of mining personnel. However, during road construction, the tunnels and underground tunnels need to detect the strata to avoid personnel losses caused by stratum displacement and subsidence without warning. [0003] The existing displacement monitoring device is usually an optical device installed on one side of t...
