摘要: 针对现有矿井巷道表面位移测量采用的十字交叉测量方法存在测量不便、耗时长、工作强度大、误差不可控等问题，设计了一种矿井巷道表面位移激光测量装置。该装置基于激光测距原理，利用激光测距仪完成十字定心和变形测量，通过单个激光测距仪可分别测得巷道中每个测试站顶板、底板、左帮和右帮4个方向的表面位移量。井下试验结果表明，该装置实现了无绳测量，测量效率高，结果准确，精度达到了1 mm，满足矿井使用要求。Abstract: In view of problems of inconvenient measurement, time consuming, high labor intensity and uncontrollable errors of existing cross-measuring methods of surface displacements of mine roadway, a laser measuring device of surface displacements of mine roadway was designed. Based on the principle of laser ranging, the device uses laser range finder to complete measurement of cross centering and deformation, and can measure surface displacements of the roof, floor, left and right sidewalls of each testing station in roadway respectively by single laser range finder. The underground test results show that the device realizes cordless measurement with high measuring efficiency, accurate results, and accuracy up to 1 mm, which meets requirements of mine.
