Underground mining hard rock and Underground mining soft rock Mantrip used for transporting miners within an underground mine Sub-surface mining consists of digging tunnels or shafts into the earth to reach buried ore deposits. Ore, for processing, and waste rock, for disposal, are brought to the surface through the tunnels and shafts. Sub-surface mining can be classified by the type of access shafts used, the extraction method or the technique used to reach the mineral deposit. Drift mining utilizes horizontal access tunnels, slope mining uses diagonally sloping access shafts, and shaft mining utilizes vertical access shafts. Mining in hard and soft rock formations require different techniques. Other methods include shrinkage stope mining , which is mining upward, creating a sloping underground room, long wall mining , which is grinding a long ore surface underground, and room and pillar mining, which is removing ore from rooms while leaving pillars in place to support the roof of the room. Room and pillar mining often leads to retreat mining , in which supporting pillars are removed as miners retreat, allowing the room to cave in, thereby loosening more ore.

The bi-modal positioning system automatically determines when the system utilizes each technology. Equipment Control Location Reason Code The optional Location Reason Code module enables operators and dispatchers to set the status and reason code for work locations. Location Reason Code integrates with Task Management to enable process execution whereby the configured mining cycle can be automated. For example, when an LHD operator has completed a task for cleaning a working face, the status and reason code of the face will automatically change to: Delay — Drilling, development.
This signifies that the location is now in a delay state until the development drill arrives. In parallel, this status and reason code change will generate a task for the development drill to work at this face. Allowing the operators to advance a mining process provides an efficient means to task automation. Task lists are not updated while working in offline mode. Benefits of the Location Reason Code module include: Use the Draw Cards module to: Generate exceptions for specific failed items, and review the Prestart history for each unity on a shift-by-shift basis.
Operators verify Equipment Prestart items on their mobile devices as part of the logon sequence. Location Checklist The optional Location Checklist module ensures operator accountability for assessing workplace conditions before commencing work at a specific location.

These areas provided fuel for heating and cooking, and later steam locomotion in the young colony of New South Wales. The first metal mined in Australia was lead at Glen Osmond near Adelaide in South Australia in followed soon after by copper at Burra and Kapunda. The value of these mines was soon overshadowed by the discovery of copper at Moonta and Kadina leading to the emigration of skilled Cornish miners and their mining technology.

Clermont Region general manager operations Dawid Pretorius said the mine has been progressively scaling back production in a transition towards closure since At its peak, Blair Athol Mine was Australia’s largest exporter of thermal coal, blessed with uniquely thick coal seams. However, as coal prices rose in recent times we looked to extend the life of the mine by mining a poorer quality coal and harder to reach seam for a few more years. Unfortunately, the recent significant drop in thermal coal prices, and other factors such as rising costs and the foreign exchange rate mean this is no longer a feasible option and we will keep to the original plan to finish production in There are currently around employees and contractors working at the operation.
There will be around 30 roles after production finishes at the site. These will include work in the coal handling and preparation plant and rail load-out facilities, which will continue to be used for coal from the nearby Clermont Mine, as well as care and maintenance work in the lead up to a rehabilitation programme.

These kids just walked into the church, dressed in suits and skirts, just like everyone else attending the wedding that day in Niagara Falls, Canada.
They had everything planned and knew who was there on the bride’s side, and who was there on the groom’s side to make sure they were seated in their proper places. They took their seats and calmly waited for their cue! When the bride Shannon decided she wanted to do something very special for her husband at their wedding, she contacted a local music school to see if they would be interested in singing “Chapel of Love” in the middle of the ceremony.
Not only did the music school agree, but they put together a whole flash mob including ten singers and five guitar players.
