基于TRT系统的金属矿山巷道施工超前地质预报:以安徽徐楼铁矿为例
|
摘要
在矿山巷道施工过程中,超前地质预报是减轻地质灾害的重要手段。本文介绍了TRT超前地质预报系统探测原理和方法,并讨论了TRT系统在金属矿山巷道施工中的应用前景。以徐楼铁矿巷道为例,结合掌子面素描法和矿区地质资料,分别对-205m和-217m水平出矿巷道进行了TRT超前探测和解译。通过对两个巷道的探测结果进行检验,预报准确率分别为70.0%和68.2%。TRT预报系统对于金属矿山巷道节理裂隙、软弱蚀变带、溶洞、矿体等具有良好的预报效果,可为巷道施工方案和安全措施的制定提供重要依据,并显著提高巷道施工进度。
In the course of mine tunnel construction,the advance geological prediction is an important means to reduce geological disasters.The detection principle and method of TRT system are introduced,and the application prospect of TRT advanced geological forecast system in metal mine laneway is discussed.Taking the construction of the tunnel in Xulou iron mine as an example,combining with the drawing method of the palm surface and the geological data of the mining area,TRT advance detection and interpretation were carried out for the two mine levels of-205 mand-217 mrespectively.Through the inspection of the detection results of the two roadways,the accuracy of the forecast was 70.0%and 68.2%respectively.The forecasting system of TRT has a good forecast effect on the joint fractures,soft alteration zones,karst caves and ore bodies in the roadway of metal mines,which can provide important basis for the development of roadway construction plans and safety measures,and significantly improve the progress of roadway construction.
