Mar 26, 2014 · Ore passes need to be designed to cut across ground levels and sub levels, in order to provide easy access to underground minerals. The intervals between ore passes should not exceed 500ft, or 150m. Ore pass inclination should be maintained between 45° and 90°, while ore pass length should be in the range of 10m to 300m

waste & ore pass design @ underground transfer points

Apr 02, 2017 · Thus, it is common practice to drive an ore-pass raise at 50° to 60° for 50, 75, or 100 feet and then “knuckle back” on a slope in the opposite direction. This often assists materially in reducing wear on ore-pass linings and preventing breakage of chutes and gates

designing reliable transfer chutes with bulk material

Apr 02, 2018 · When the final design 3D model is adequate, we will run a DEM simulation of the chute which we then use to optimize the final chute design. Here is a real-case example of a project we worked on for a client. A vertical Ore Pass section of approximately 105 meters is filled with Kimberlite. The material can drop 105 meters and impact onto a

Spillminator Chute criteria. We offer SideWall Chutes, HangingWall Chutes, and Belt Feeders. In accordance with SANS specification 0208, the Chute is designed for a nominal design pressure of 840 kPa in platinum mines and 600kPa in gold mines. 840 kPa is equivalent to a 30m ore pass filled with UG2 slurry (hydrostatic head)

general 5 — last ditch mining

The Cariboo Hudson Mine. The Cariboo Hudson Mine is located at the headwaters of Pearce Creek, a feeder of the legendary Cunningham Creek. Gold quartz ore bodies were known on Yanks Peak and Round Top Mountain as early as the 1860s, but were not heavily exploited until the 1920s when local prospector Fred Wells explored the surface veins at Pearce Creek and began sinking shafts and adits

analysis of ore pass hang-ups in long vertical ore passes

Sep 01, 2020 · A problem is that ore pass hang-ups in vertical ore passes can cause extensive damage during mining operations [2-8]. As is well known, there are two types of hang-up. One is the interlocking hang-up, which is governed by the ratio of ore size to the ore pass diameter [5]

ore and waste passes - queensminedesignwiki

Ore and waste passes. An ore pass refers to an inclined passage used for the transfer of material in underground mine workings. Ore passes are designed to utilize the gravitation potential between levels in order to minimize haulage distances and facilitate a more convenient material handling system. The term ore pass is a misnomer since all

The goal of this research was to improve monitoring, inspection, and operating procedures to increase awareness of the proper functioning of mine hoists, ore passes, and chutes; develop means of warning of potentially dangerous situations; and to improve the design of mine shaft and ore pass

comparison of ore pass computer simulations for designs

A PFC2D simulation showed that dynamic loads at the chute gate were reduced significantly when a dogleg transition was used, and simulations in which the ore pass was inclined showed significant reductions in chute impact loads compared to simulations of a vertical ore pass. A released hang-up was simulated using PFC2D

Feb 05, 2020 · The ore then collapses – or “caves” – gradually under its own weight. The resulting rubble funnels through a series of vertical ore passes at various levels in the mine. A chute system is located at the bottom of each ore pass. “The chute is a device that allows ore to be transferred safely to the haulage vehicles,” Meloche explained

ore-pass dimensions in scraper winning | springerlink

1. Present-day ore-pass dimensions are impeding an increase in productivity of men and faces and in the rate of the mining-out process. 2. Optimum ore-pass chute dimensions are as follows: width 2.0 m and height of passage orifice 1.2–1.3 m. For such chutes there should not be more than two cases of ore sticking per shif. To attain these chute dimensions, the height of the haulage working
