神东矿区超大断面明槽开挖段井筒支护参数研究
|
摘要
结合神东矿区表土段典型地层情况,对超大断面斜井明槽开挖段井筒的支护参数进行计算分析,得出了不同井筒净宽、不同覆土厚度下井筒结构的计算模型,并形成相应的设计标准。研究成果应用于神东矿区上湾矿井新副斜井明槽开挖段井筒支护,其支护效果良好,井筒结构稳定,为后续参考标准的推广提供了有力依据。
Based on the typical strata situation of the topsoil section of Shendong area,the supporting parameters of the shaft of the excavation section of the oversize inclined shaft are calculated and analyzed. The calculation model of wellbore structure in different wellbore width and thickness is obtained,and the corresponding design standard is formed. Research results applied to the east of mine bay on the new auxiliary slope excavation section of shaft support, the supporting effect is good, the stability of wellbore structure,for subsequent reference standard promotion provides strong basis.
