Sommaire: Loading and transportation are important activities of the mining process. Automation of these activities in underground hard rock mining has been discussed for a long time. This paper deals with the performance evaluation of a prototype automatic Load-Haul-Dump (LHD) vehicle (a 7-ton GHH LF LHD model) operating in Zinkgruvan mine, Sweden. The purpose of the data analysis is to evaluate the operational and maintenance characteristics of the automatic LHD system in the mine. Graphical and...

Sommaire: At Dofasco's No. 4 furnace a variation of the basic oxygen steel-making process, Klockner Oxygen Bottom Maxhutte (K-OBM), is used to produce steel. Large amounts of hot gases and paniculate are evolved during the oxygen blowing phase. A quencher and a venturi scrubber are used to collect over 99.5 % of the paniculate. In 1990, the authors investigated the effect of foamy slag on the paniculate emissions from the furnace. The amount of lime added early in the oxygen blowing cycle was reduced,...

Sommaire: Many of the ore bodies presently being developed are in remote locations and are, or will be, served by electrical power supply systems of limited capacity.The largest single components of the electrical systems of an underground mine are usually the production hoist drives; the power demands of these drives vary continuously throughout each hoisting cycle.
Before 1970 mine hoists were driven by either wound rotor induction motors or DC motors in conjunction with motor-generator sets.Static...
