摘要
Abstract
Technical difficulties such as continuous crushing,unstable collapsing,and resource overlaying affect the roof surrounding rock of the large diameter deep hole stope in Jinchanghe polymetallic ore.To address the mentioned issues,an optimal design for an industrial test of a roof retention and protection system was developed for the 29# stope.On-site applications indicate that this retaining and protective structure can withstand changes in mining stress,effectively controlling roof deformation and providing improved anchoring performance.关键词
