MECHANISED DECLINE DEVELOPMENT

MMS System for 4m wide 26º decline:

MMS System - Excavator

 

MMS System - Jumbo

MEDIUM TO HIGH SPEED HAULAGE DEVELOPMENT

The Hopper Loading System patented by Mario & Romano Pietromartire can be used in tunnels and haulages where medium to high rates of advance, are required. The principle of loading spans of hoppers with the system utilising a face ‘Hagg’ or similar loader achieves cost effective, high rates of mucking. The working prototype confirmed the designed tunnel face-loading rate of 50 to 60 t per hour

Working together with the Hopper Loading System an Equipping Service Utility Car has been designed to complement high development rates with efficient installation of rails and services.


MECHANISED STOPING

Developed and patented by Mario Pietromartire the Megamole is a stoping machine designed to be applied, in the typical narrow platinum reef in South Africa.

Bomar is in the process of negotiating a trial project for the prototype. The concept and design and detail design of the cutter head drives and circuitry is complete.

MINE TUNNEL BORING MACHINE

Bomar has commissioned the design of a TBM intended specifically for mine layout and physical conditions encountered on South African platinum mines.

The MTBM is unique in a variety of respects. For example, the 2.18 m diameter TBM will have double the power of a machine which has been tested successfully in the South African mining environment. In addition it will be remote controlled, less than 6 m long and will be capable of very small vertical turning radius which will permit the machine to follow the reef in its “rolls”.
