Optimization Design and Application of Mine Development Technology
In mine development,support operation plays a crucial role in the process of excavation.For the traditional technology using metal mesh and technology bolt layout can not fit the rock wall,resulting in low bolt force,can not play a firm role in the surrounding rock.This paper puts forward the method of using shotcrete to develop roadway,specifically describes the technology of multi-shotcrete support,and carries out practical application in a mine.The results show that:Using the new support technology,the support quality is significantly improved,the deformation degree of roadway surrounding rock is reduced by 58%,effectively prevents the shotcrete layer from being subjected to pressure deformation or cracking over a long period of time,and reduces the support cost.
