同煤集团塔山雁崖扩区巷道贯通技术研究

摘要

That paper Combined with engineering practices and regulatory requirements,study in depth the use of the instruments and methods in the work of tunnel connection about 8101 workface on 4#layer which is in Datong Coal Mine Group Tashan Yanya Expansion Area. Using scientific theory, with the integration estimate of the angle and length measurement error,offered the connection error estimate result. It turned out that the instruments and the connecting way can achieve the desired objection and complied with regulatory requirements.%该文结合工程实际及规范要求对同煤集团塔山雁崖扩区山4＃层8101工作面巷道贯通工作中采用的仪器及方法进行了深入研究。运用科学的理论方法，通过对测角和量边误差的综合预计，最后给出了贯通误差预计结果。结果证明，所用仪器及该贯通方式能够达到预期目标并符合规范要求。
