roadway deformation

基本解释

The deep roadway deformation problem is becoming increasingly serious, much maintenance increases support costs and security is difficult to guarantee.
大采深巷道变形问题日益严重，巷道需要多次维修增加支护成本、安全难以保证。
Because the natural stress field is changed due to tunneling roadway, a stress concentration area appears in rock of surrounding roadway that cause roadway deformation or destruction.
由于巷道掘进破坏了原岩地应力场，使围岩应力重新分布，应力集中区的高应力造成巷道变形破坏。
The results provide a basis for controlling additional roadway deformation efficiently and ensure the regular production of the mine.
为有效控制跨采巷道附加变形，保证矿井正常生产提供了依据。

巷道变形
The deep roadway deformation problem is becoming increasingly serious, much maintenance increases support costs and security is difficult to guarantee.
大采深巷道变形问题日益严重,巷道需要多次维修增加支护成本、安全难以保证。本文根据范各庄深井开采条件,深入分析巷道变形影响因素,提出可行的支护对策,保证深井巷道服务期间内稳定。
