摘要
贯通巷道的横向偏差对巷道质量及用途的影响严重。针对影响煤矿贯通巷道横向精度的贯通测量因素,探讨了提高测量精度、减小贯通巷横向偏差的措施。
Roadway quality and application are severely affected by horizontal deviation of perforation airways. For influential factors on the horizontal precision in breakthrough survey, the paper discusses some measures to increase the measurement accuracy and reduce the horizontal deviation in the perforation airway.
