The invention relates to the technical field of mines, and provides a mining fully-mechanized excavation face excavation progress measuring system and method. The mining fully-mechanized excavation face excavation progress measuring system comprises a measuring device and a wireless distance measuring base station, the measuring device is used for being arranged on the side of a tunneling machine, and the measuring device comprises: a laser sensor which is arranged perpendicular to the roadway side coal wall and used for detecting the distance between the measuring device and the roadway side coal wall; a wireless ranging sensor which is configured to interact with the wireless ranging base station to detect the distance between the wireless ranging sensor and the wireless ranging base station; and a control processing module which is connected with the laser sensor and the wireless ranging sensor. The wireless ranging base station is connected with the control processing module, is arranged at the initial tunneling position on the side coal wall of the roadway irradiated by the laser sensor, and is used for processing the measured distance data to obtain the tunneling progress. The system can effectively avoid the influence of dust on measured data, improves the accuracy of the measured data, and has the characteristics of convenience in installation and easiness in field use.
Description
Technical field [0001] The present invention relates to the field of mine, and in particular, to a mine coverage system and method. Background technique [0002] With the continuous development of mine technology, comprehensive mining technology has the characteristics of efficient, high-yield and safety, has become the main technique of thick coal seam mining. [0003] Currently exploiting the commonly used drive measurement method to mount the infrared laser ranging device on the driving front end of the excavator, and install the target, and measure the measurement of the progress by measuring the laser return time. However, when the coal mine supporting surface, the front-end spironolastic surface dust is very large, which seriously affects the normal work of the laser, causing the measurement results to be lost, and a lot of homework is caused. Inventive content [0004] The present invention provides a mine coverage-making feature system and method, and the measuring devic...
