Research on tunnel drilling technology in Xitieshan mining area,Qinghai Province
摘要
Abstract
In recent years,the main ore belt of Xitieshan has gradually entered deep exploration,mainly relying on tunnel drilling to determine the distribution and reserves of deep mineral deposits in the mine.During the implementation of tunnel drilling,challenges such as airport chamber support,drilling of fractured strata,core extraction of water sensitive strata wall protection,and treatment of water inrush strata are faced.If not handled properly,it can cause airport chambers to fall and collapse,and drilling accidents such as jamming,burying,and collapse may occur.In severe cases,drilling may be scrapped,which restricts the exploration process.In response to the technical difficulties in drilling complex formations mentioned above,research has been carried out on strengthening tunnel support,selecting reasonable drilling parameters,optimizing drilling structures,formulating complex formation flushing fluid formulas,and using rapid setting cement for sealing.This has ensured the construction safety of the tunnel airport,effectively solved the drilling difficulties in various complex formations in the area,reduced the incidence of accidents and drilling scrap rates,improved drilling efficiency and quality,and provided reference for subsequent drilling construction in similar formations.关键词
