SUPPORTING PROCEDURE AND FIELD MEASUREMENT IN THE SHAFT THROUGH GLIDING TECTONIC GROUND

         

摘要

The paper describes mechacal properties and deformation features of shaft adjoining rocks in gliding tectonic ground and presents the shaft-supporting procedure of smooth-wall cushion blasting,preliminary bolting and shotcreting and pouring reioforced coocrete liner in one-time-whole-section on the basis of adjoining rock deformations measured dynamically site. Field measurements of the pressur exerted on shaft wall show that this supponing procedare has enough safety reserve to meet the safety requirements in mining production.
