马脊梁煤矿井下巷道贯通测量方法分析

Analysis of Holing-through Survey Method in Underground Roadway of Majiliang Colliery

在煤矿测量工作中,贯通测量是其中重要工作之一,确保贯通点的误差在设定的范围内,决定了贯通测量的成败。本文将马脊梁煤矿副立井与王村回风立井的贯通作为研究对象,选择使用井下控制测量、竖井联系测量及陀螺定向技术等,设定了贯通测量的方案,开展了误差预计,通过对比预计结果和要求,保证了贯通测量设计的可行性。

The paper probes into the holing through survey between auxiliary shaft of Majiliang Colliery and air-return shaft of Wangcun Colliery,including technologies of underground control survey,shaft connection survey and gyro-positioning,and determines the holing-through survey scheme by comparison with the error prediction results and demand to guarantee the feasibility of holing-through survey design.
