工程物探在新桥金硫铁矿矿山建设中的应用

Application of Geophysical Prospecting to Mining Construction in the Xinqiao Au-bearing Pyrite Mine, Anhui

新桥金硫铁矿在矿井建设中,井下硐室未找到所设计的充填钻孔位置.我队用磁法测到了磁力高或磁场急剧变异处,经现场分析,指出了硐室掘进方向,准确地查明了3个井下充填钻孔所在位置.

In the Xinqiao Au-bearing pyrite mine under construction, Tongling, Anhui, some of the designed filling boreholes were missed in underground chambers. For the purpose of finding these missed holes magnetic method was used. By an analysis of the measured magnetic highs or anomalies of large gradient on the spot, the driving direction for the underground chamber was shown immediately. The locations of three missed filling holes were found in such a way and proved through driving.
