Exploration of Improvement Measures for Construction Technology of Auxiliary Shaft Inset in Non-coal Mines
Shaft inset is an important node in mining engineering,but there are also several construction difficulties due to its complex structure,large-section excavation,and large supporting area.To solve the problem that the delayed construction progress of the shaft inset negatively affects the overall investment and construction of the mine,to ensure that the shaft inset is completed within the planned time,to save the labor cost,equipment cost and other related costs,and to improve the construction efficiency,the auxiliary shaft inset of Hualinggou Iron Mine of Bensteel Mining is taken as the research object to be explored and improved.Based on the existing engineering and technical conditions,scientific discussions are conducted in terms of construction technology and organizational arrangements.Rectification measures are mainly proposed from the aspects of excavation and support.On-site practice has proven that it can improve work efficiency by 50%and achieve the construction goal of safety and efficiency enhancement.
