英文摘要
Ore and waste handling in most underground mines is based on a network of vertical or steeply inclined ore and waste passes. An ore pass is comprised by a number of sections of different length. A section is defined as a segment of an ore pass that links two levels and excavated in one run. Although it is typical to observe changes in orientation from a section to another, this is not necessary. Material transfer is an integral part of the mining process; with rock pass related problems resulting in operational and economic significance. Operational concerns include hang-ups due to arching of material, blockage and degradation of the rock pass. Ore passes that require rehabilitation or intervention to liberate blockages (hang-up) may pose safety concerns for the work force.
