Abstract

The invention discloses a mining roadway rock displacement monitoring device for underground engineering, which comprises a mounting plate installed on the top wall of the roadway, a measuring mechanism is installed on the lower end of the mounting plate, and two symmetrically arranged on the side wall of the roadway. A balance mechanism is installed in each of the detection grooves and the bottom of the roadway, and the measurement mechanism includes a measurement box. The present invention increases the comprehensiveness of detection through two balance mechanisms, and connects the balance mechanism and the measurement mechanism through ropes for detection. The column realizes the balance of the measurement box, which is convenient for long-term use of the device. The balance mechanism, rope and double wheel groove mechanical structure are located outside the measurement box for transmission, and the feedback disc, light sensor and light emitter are located inside the measurement box to reduce external interference to the measurement and Increase the accuracy of measurements.

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...
