Blasting in Coal Mines •Modern mechanised coal mines use machines and longwall mining methods to cut solid coal and convey the broken coal out of underground workings. •Continuous mining equipment has escalated coal production and introduced effective and efficient coal handling facilities.
Founded in 1943, Usibelli Coal Mine (UCM) has grown to become the largest coal mining operation in Alaska utilizing the most modern mining equipment and state-of-the-art engineering to supply coal to six Alaska power plants and export coal to Chile, South Korea and several other Pacific Rim destinations. UCM sponsors many community events and activities, and through The Usibelli Foundation.
The conventional mining techniques described above, made up of the cyclic operations of cutting, drilling, blasting, and loading, developed in association with room-and-pillar mining.The oldest of the basic underground methods, room-and-pillar mining grew naturally out of the need to recover coal as mining operations became deeper and expensive.
The Solntsevsky coal mine is an open-pit coal mining operation by East Mining Company (EMCO) in the Sakhalin region of Russia. Although experimental mining in the Uglegorsk region was started in 1983, the Solntevsky coal mine became the first open-cast mine to commence commercial operations in the Sakhalin mining region in 1987 In 2011, EMCO acquired the licenses to work at the Yuzhnuy-2.
Mining(breakage and loading) shearer(normally a double drum version),plow. Haulage ar d chain-and-flight face conveyor, normal belt conveyor utilized in the head gate entry set. The success of the operations of longwall mining as one the the conventional underground coal mining methods is highly dependent upon the mine design and layout.
The Mining Machinery Division of Ostroj a.s. is an established manufacturer of mining machinery and specialized equipment for coal mining. We manufacture high quality shields, AFCs, BSLs, Boot Endsand associated equipment for the most demanding coalface operations, as well as specialist equipment for steep seam extraction at angles of over 40 degrees, including shearers and shields.
A coal mine was experiencing heavy spillage and system damage along the length of a main conveyor due to inadequate loading zone equipment. Impact idlers allowed excessive belt sag, causing high volumes of spillage.

Devices related to the transportation of coal from the mine to processing facilities to rail loading and finally to the consumer conveyors, underground and overland barge ship railroad trucks Also includes devices related to the processing of coal including coal sampling and testing laboratories coal preparation equipment.
It is also the first coal mine in the world to transport one billion tons of coal and has shipped than three billion tons of coal during its mine life. Construction at Black Thunder began in 1976 with the installation of crushing, conveying, sampling and high-speed train-loading systems. All plant processes are computer-controlled.
The Mines Today. From the days of the salt industry until the 1940s, most coal was loaded using hand tools like picks and shovels. Machines were introduced gradually during the early 1900s, allowing miners to load coal in less time. Mechanization began with undercutting machines around 1900 and advanced to loading machines in the 1920s.
Operate mining machines that rip coal, metal and nonmetal ores, rock, stone, or sand from the mine face and load it onto conveyors or into shuttle cars. There are roughly around 3,500 of these workers found in Coal Mining. You will find these workers assisting in construction activities, checking the roof stability and cleaning equipment.
Many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers’ pneumoconiosis (CWP). CWP is a lung disease that can be disabling and fatal in its most severe form. In addition, miners can be exposed to high levels of respirable silica dust, which can cause silicosis, another disabling and or fatal lung.

Chaiwei - Model CW-500GF-WKI - Coal Mine Gas Generator Set. Coal mine gas is a kind of burnable gas without any color,taste and smell . It will explode if the concentration ranges at 5~6 ,and if oxygen large than 12 ,it will also explode when meets the naked light or temperature between 650℃ to 750℃. Explosive power will be biggest if.
Our technicians do repairs, redesigns, upgrades, and full rebuilds for a variety of underground mining equipment. This includes continuous miners, shuttle cars, loading machines, bolters, coal haulers, scoops, feeder breakers, tunneling machines, and rail equipment. Scopes of work can range from component repairs to ground-up rebuilds.
Fleet management systems help coal miners answer these questions quickly and efficiently. They enable the scheduling and assignment of all types of equipment—haul trucks, loaders, drills, draglines, light vehicles, fuel trucks, support machines and —from a central office location. That helps minimize unproductive machine wait time.
Dec 04, 2012 Having sat unused since 1995, Mr. Tom, one of the biggest coal mine draglines in the country, had turned into a rusting hulk, seen only occasionally by a handful of dirt bike and motorcycle.

The export quality product is conveyed to silos and then to a load-out silo at the rapid load-out terminal for transportation to the Richards Bay Coal Terminal. Khwezela Colliery The Khwezela Colliery is an open cast thermal coal mine located about 120 km east of Johannesburg and approximately 22 km south west of eMalahleni in the Mpumalanga.
On reaching the conveyor, the unloading jib section is raised to enable coal to be discharged into the breaker feeder or directly onto the conveyor (depending on the mine's relevant equipment and practices) and the scraper conveyor is run until the car is empty. This car will then return to the mining machine or to the passing shunt to await.
