摘　　要：为了保证王家塔矿井3107主运巷在经济合理的条件下实现顺利贯通,结合3107主运巷相关的测量资料,编制了3107主运巷的贯通测量方案,并分别对加测陀螺定向边、不加测陀螺定向边以及提高测角精度这三种测量方案进行误差预计分析,结果表明:不加测陀螺边时K点在X'轴的预计误差为0.496m,加测陀螺边时K点在X'轴的预计误差为0.170m,提高测角精度时K点在X'轴的预计误差为0.178m,加测陀螺边和增加测角精度均能满足工程要求。最后,结合经济因素,确定以提高测角精度作为贯通测量施测方案并实现巷道顺利贯通,最终贯通点在X'轴上的贯通误差仅0.118m。To ensure the economic and smooth holing-through of 3107 belt conveyor roadway in Wangjiata coal mine,a holing-through survey scheme is made combining with the relevant measurement data.The error of three schemes is predicted and analyzed,including the scheme with additional measurement of two gyroscopic directed edges,without survey gyroscopic directed edge,and that with enhanced angular accuracy,and the results show that： prediction error of K point in X＇ axis of the second scheme is 0.496 m,that of the first scheme is 0.170 m,and that of the third scheme is0.178 m,the first and third schemes can satisfy engineering demand.At last,the third scheme is applied considering the economic factors and implemented successfully,and the error of final K point in X＇ axis is only 0.118 m.
