Large scale mechanised mining methods we use include: long-wall mining, where a long wall of coal is mined in a single slice, usually by a large machine. sub-level-caving, where levels of the ore are blasted by explosives; and ; block caving, where large areas of the ore body are blasted and then extracted with the assistance of gravity. We use these three different types of underground mining ...
other specialist geotechnical operations shall be achieved by either of the following methods: a mechanised tool-handling system be fitted to the rig, for example a carousel, magazine; or a mechanised tool-handling device that can be attached to supporting equipment, such as an excavator's quick-hitch.” The Group will review and present the options currently available in the market to ...
Mining methods at Impala. The Merensky and the UG2 Reefs are mined concurrently though the conventional double-sided breast mining method. The central shaft position is cross-cut in the opposite direction by the haulages. The footwall drives are developed at approximately 18m to 30m below the reef horizon with a 180m and 250m separation between the on-reef connections. The panel face lengths ...
In South Africa, traditional methods of mining are well entrenched after more than a century of mining. To successfully change from these methods requires an integrated holistic approach that considers all aspects of a mining operation including setting of objectives, selection of personnel, recruitment, training and remuneration policies, organizational design, mine design, equipment ...

Mechanized mining technical process (MMTP) related to the control method of the shearer is a vital process in thin coal seam mining operations. An appropriate MMTP is closely related to safety, productivity, labour intensity, and efficiency. Hence, the evaluation of alternative MMTP is an important part of the mining design. Several parameters should be considered in MMTP evaluation, so the ...
The majority of his experience is related to Trackless Mechanised Mining methods, the selection and training of top quality operators as well as Mine Planning and Equipment selection. He has managed this companies Zambian operation for 6 years and has achieved outstanding results in weak ground mining. Otto has been involved in the development and establishment of 3 decline operations and ...

ALEC HOGG: Mechanised mining is a predominantly South African initiative in the mining industry worldwide. However, most overseas mining companies have moved towards mechanised mining methods, where as here, we still seem to be using the old pick and shovel. Joining us for more is Dr Jeanette McGill, Head of Novel Mining Methods at the CSIR. Jeanette, we had a fascinating
Mechanised drivage. April 1995. John Chadwick; Modern mines require ever faster development methods. This is especially true of today's long-wall coal operations which have an enormous appetite ...
This mining method is useful because it allows for huge volumes of material to be mined at relatively low costs, which makes lower grade deposits economical to turn into mines or new pits. Many large-scale open-pit operations have plans to progress into block caving operations over time, including Oyu Tolgoi and Grasberg. This mining method is typically used in situations where the orebody is ...
The project at Target has resulted in the design of a method of resue mining which can be entirely mechanised, hence made viable. A practical stoping layout has already been developed. Equipment ...

conventional stoping methods, and the second a fully mechanised bord-and-pillar mining method. Both methods are feasible mining options, but which method is the most profitable? Industry data will prove that if focussed on mining cost alone, typically the higher volume method will result in the lower unit cost per mined tonne. This could be used as a selection criterion, but an experienced ...
introduce a mechanised massive mining method at depth to destress and then extract the extensive orebody. The destressing method then had to allow a productive method for economic extraction of an essentially low-grade bulk volume orebody. Several variations of different mining methods have been used to date but all rely on a destressing method to reduce the in situ stresses. Originally the ...

The mechanised form of this mining method has potential for application in the metalliferous mining industry in Australia. In this study a comparison is made between mechanised updip (MUDS) and transverse retreat stoping (TRS) methods. A hypothetical nickel sulphide orebody located in Western Australia is used as case study. The net present value for mechanised updip stoping is seven per
