井下采区大巷贯通测量方案的优化研究

Optimization Research on Measurement Scheme of Tunnel Threaded Together in Underground Mining Area

为了提升煤峪口矿主运输巷道贯通作业时的经济性和效率,本文根据煤峪口矿井下的地质情况及测量数据,提出了一种新的井下采区大巷贯通测量方案,对不同测量方案下的测量误差情况进行了研究。通过在煤峪口矿井下的应用表明:采用提高测角精度的贯通方案,其贯通误差约为0.186 m,满足井下大巷贯通测量要求。

In order to improve the economy and efficiency of the main transportation roadway threaded together,the paper proposes a new underground roadway penetration measurement scheme based on the underground geological conditions and measurement data of Meiyukou Mine,which satisfies the requirements of underground tunnel penetration measurement.
