深厚冲积层超深冻结井筒井壁结构设计

Ultra Deep Alluvium Deep Freezing Shaft Wall Structure Design

针对杨村煤矿主、副、风3个井筒冻结段较深、科学合理的选取外荷载进行井壁结构设计的问题,从设计过程中参数的选取、影响井壁结构设计的各种因素入手,分析阐述深厚冲积层超深冻结井筒井壁结构设计过程,为井筒安全顺利通过深厚冲积地层打下基础,也为东部地区相似情况提供了设计参考。

Based on Yangcun Mine main shaft, deputy shaft, wind shaft deep freezing section, how to select the loading for scientific and reasonable about the design of the shaft wall structure, from the selection of the design process, the various factors influencing the shaft wall structure design deep alluvium deep freezing shaft wall structure design process was analyzed, which laid the foundation for wellbore safety smoothly through the deep alluvium formation and provided design reference for similar situation in the east.
