摘要
国内金属矿山深部采矿,采用钻爆法工程工期很长,不确定的各项风险较大。TBM法施工速度快、安全、质量好,在水利、市政、公路等运用已很广泛。“四新技术”的不断应用,设备的不断改进,国产TBM性能和质量不断提升,施工成本也大幅降低。但是TBM法开拓深部采矿巷道还没有应用,主要原因是矿山深部地质情况复杂,巷道断面不一,TBM适应性差。本文分析了TBM法用于金属矿山深部巷道开拓可能遇到的涌水、岩爆、高地温等风险,并对这些风险应对措施作了阐述。认为采取措施后可以消除这些风险,TBM机可以在金属矿山深部巷道中试验应用。
In domestic metal mines,the drilling and blasting method is used for deep mining,and it has a long construction period with high risks.The TBM method has been widely used in water conservancy,municipal engineering and highway construction because of its fast construction speed,safety and good quality.With the continuous application of“four new technologies”,the continuous improvement of equipment,and the continuous improvement of domestic TBM performance and quality,construction costs are significantly reduced.However,the TBM method has not been applied to develop deep mining roadways.The main reasons are:the deep geological conditions of the mine are complex;the roadway cross‑sections change,and the adaptability of TBM is poor.This paper analyzes the possible risks of water inrush,rock burst,high ground temperature and so on when the TBM method is used in deep roadway development in metal mines,and expounds the solutions for these risks.It is concluded that these risks can be eliminated with the solutions,and TBM can be applied in deep roadway boring in metal mines.
