Mopani Copper Mines Plc. (MCM) is sinking a vertical rock and man shaft. The rock hoisting winder will handle 2.0 million tonnes of ore per annum. The project will significantly boost the current productivity of Mindola Mine, as it will enable the company to increase ore production from 800...

There has been a lot of outcry from the public that Zambia’s mineral tax reforms, with an aim to optimize revenue benefits from the mines, have not yielded the desired results. This has mainly been attributed to the weak design of its legislated mineral taxation systems. Due to this underlying...

The objective of this research was to characterise the rockmass to determine appropriate support system for the decline with the 4.5m height and 4m wide in highly aquifer strata, recharging the water flow of 18, 000 cubic meters per day. As a result production targets reduced due to excessive...

Attempts to develop Threshold Limit Values together with the correlation between results of various sampling instruments are described. The main objectives of the investigations were: to establish the relationship between dust exposure and the development of pneumoconiosis, to study the effect of...

Field and laboratory measurements of rock properties were conducted to investigate the behavior of rock masses at Chibuluma East deep levels. Intact rock strength was obtained by point load testing, Joint spacing, Joint condition, separation of Joints and the infilling materials were determined...

This dissertation describes an investigation carried out at Baluba Mine to assess the quality of rock mass and support requirements in haulage drives developed in the -footwall quartzite -Formations. The rock mass o-F the -Footwall Formation is geotechnicallv quantified using the Modi-Fied Basic...
