提升煤矿井下巷道贯通测量精度的实践分析

Practical Analysis of Improving the Accuracy of Coal Mine Underground Roadway Through Survey

煤矿井下巷道贯通测量的质量对整个矿井生产的影响较大,全面提升煤矿井下巷道贯通测量精度较为关键。本文将郭庄煤矿井下贯通测量作为实际分析案例,对比选择了贯通测量方案,分析了本次矿山测量的精度要求,设计了地面、井下的平面控制、高层控制方案,计算得到贯通误差预计均小于设计精度,为现场贯通施工提供了依据。

The quality of tunnel through surveying in coal mine has great influence on the whole mine production,and it is the key to comprehensively improve the accuracy of tunnel penetration measurement in coal mine.In this paper,the hole through measurement of Guozhuang Coal Mine is taken as an actual analysis case,the penetration measurement scheme is selected,the precision requirement of the mine measurement is analyzed,the plane control and the high rise control scheme are designed for the ground,underground,and the calculation is less than the design precision,which provides the basis for the field through construction.
