Abstract: Underground mining phase pioneering design in mine production occupies a very important position,especially the layout of the stage to open up to wear pulse spacing and mining areas in the chute,a great influence on project investment and operating costs of mining enterprises.In this paper,according to stope wearing veins transport engineering,mining district the minimum chute engineering investment and mining field DSO cost of and the minimum principle and mining field transport function principle the establishment of a stage to develop transport wear pulse spacing,stope slipped well spacing mathematical model the Xingshan iron ore-330m stage pioneering design and used to calculate the wear pulse spacing 100m,chute pitch 67.5m wear veins,chute spacing parameters to provide a reference for future similar mines reasonably determine.
