摘　　要：为保证贯通测量的顺利完成,对胡家河煤矿二号进风立井、回风立井及副立井、二号风井的大型贯通测量问题进行了探讨。通过对贯通线路长、立井井筒深、观测条件复杂等技术难点和不利因素进行分析,在地面控制测量、立井联系测量、井下导线测量、陀螺定向测量等方面提出了有效措施,设计了贯通测量方案并进行了贯通误差预计。实施了副立井联系测量、已掘进巷道的导线测量及陀螺定向测量工作,对贯通方案中各项参数设计的合理性进行验证。结果表明,贯通测量方案技术冗余度较大、整体可靠。In order to ensure the successful completion of the through survey,the large-scale through measurement of the No.2 intake shaft with return air shaft,and the auxiliary shaft with No.2 air shaft in Hujiahe coal mine is discussed.Through the analysis of technical difficulties and unfavorable factors such as long through line,large depth of vertical shaft and complex observation conditions,the effective measures are put forward in the aspects of ground control survey,vertical shaft connection survey,underground traverse survey and gyro orientation survey,the through survey scheme is designed and the breakthrough error is predicted.Through the implementation of auxiliary shaft connection survey,traverse survey and gyro orientation survey of driving roadway,the rationality of various parameters in the through survey scheme is verified.The results show that the through survey scheme is reliable and the technical redundancy is relatively large.
