For underground coal mine wire measurement, due to the impact of the construction environment, wire measurement labor intensity, poor measurement efficiency, low accuracy and other technical problems, Lu'an Group Sima Coal Industry analyzed traditional underground coal mine wire measurement methods and the main problems, and according to the actual situation of the wire measurement methods to a reasonable optimization of the "long-angle short-edge wire measurement method", through the 1208 transport roadway and cut roadway through construction of the application of the results, the optimized wire measurement method was adopted to reduce the number of instrument leveling in the alignment, improve the accuracy of wire measurement, with significant results.
