Design Innovation and Reflection on Promoting TBM Application at the Source of Super Large Scale Hard Rock Mines
The Xi'anshan Iron Mine is a super large scale mine,and the use of TBM to construct belt slope and ramps is the first application of this technology in domestic underground iron mines.There are significant differences between TBM construction and drilling and blasting construction in terms of exploration,design,and construction.Based on the TBM construction of iron mine shaft engineering,combined with equipment performance and development system process requirements,this article innovates the application of inclined shaft route planning,curve radius selection,starting site design,starting and receiving section support,normal section support selection,roadway floor treatment,and opening design form.At the same time,combined with the problems encountered in project design and construction,an analysis and discussion were conducted on the technical requirements for TBM construction survey applicable to mining engineering,the selection of construction plans,and the improvement of TBM construction section utilization rate.
