The invention belongs to the technical field of coal mining and particularly relates to a measuring system for ultrasonic detection of coal mine roadway surrounding rock. The measuring system is composed of a plurality of measuring modules; each measuring module comprises two measuring units; the measuring units comprise data lines wound on paying off wheels on paying off frames and pipeline robots connected with one ends of the data lines; the other ends of the data lines are connected with first wireless signal transceivers; and the first wireless signal transceivers are in wireless signal connection with second wireless signal transceivers of a control terminal. The measuring system is ingenious in design and enters the coal mine roadway surrounding rock from a hole channel punched in sampling, and data of the coal mine roadway surrounding rock can be efficiently and accurately detected and transmitted.
Description
technical field [0001] The invention belongs to the technical field of coal mine mining, and in particular relates to a measurement system for ultrasonic detection of surrounding rocks in coal mine roadways. Background technique [0002] Coal, as the main energy source in our country, has contributed a lot to the economic and social development of our country. In the primary energy consumption structure in the world, fossil energy still occupies a dominant position and will continue for a long time. With the rapid development of my country's economy, the extensive development model of exchanging energy for benefits cannot be fundamentally changed in the short term, which has led to a large demand for coal resources in the industrial market. So far, with the increase of coal mining intensity, surface shallow resources are almost exhausted, mineral resources have shifted from shallow mining to deep mining, and the thickness of high-quality coal seams that can be mined graduall...
