Continuous miners operate a room and pillar mining system. A series of 18 to 20 foot wide rooms are driven in the coalbed with pillars or columns of coal left standing to help support the roof. Roof bolts, typically four to six feet long steel bolts, are inserted into holes bored into the roof to bind the strata together support the roof ...

We did a survey to ask other Continuous Mining Machine Operators what degree they had when they became a Continuous Mining Machine Operator. Here are the results. High School Diploma. 81.27%. a Post-Secondary Certificate. 9.64%. College Certificate. 5.13%. One of the most common questions that we always get is what major …

Truly continuous mining will require innovative fragmentation and material-handling systems. In addition, sensing, analyzing, and communicating data and information will become increasingly important. …

MC470 is a continuous miner designed for operations that require the highest cutting force, including room and pillar coal mines, salt and potash mines. The miner …

The number of heads in a sequence of coin tosses. The result of rolling a die. The number of patients in a hospital. The population of a country. While discrete data have no decimal places, the average of these values can be fractional. For example, families can have only a discrete number of children: 1, 2, 3, etc.

Through continuous surface mining methods, today's miners are actively taking steps to make mines safer, more sustainable and better neighbors to nearby …

Continuous surface mining methods can help you optimize productivity and precision on the jobsite, especially when you use a Vermeer terrain leveler. Read more.

The benefits. Continuous hard rock mining systems offer the potential for easier scheduling, much safer and faster advance rates and greater productivity than conventional drill and blast, which averages about five metres per day. "We are seeing our technology can achieve 10 metres a day," said Ramström.

The optional ergonomic graphics display provides easy access to visualization, parameters, logs and help. Screens can be accessed via the transmitter and parameter changes can be made. The unit allows three modes of control: wireless for normal operation, umbilical and a mode for troubleshooting. Graphics display.

MC470. MC470 is a continuous miner designed for operations that require the highest cutting force, including room and pillar coal mines, salt and potash mines. The miner integrates proven technologies to offer high advance rates under tough mining conditions and in restricted spaces.

The line of Continuous Miners includes products for both soft and hard cutting applications, in any seam thickness — for seams as low as 810 mm (32 in) up to 4.7 m (15.4 ft). All continuous miners offer: Wide conveyor for maximum loading rates. Wide crawlers for maximum penetration and low ground pressure.

However, coal mining men, who have the longest and broadest experience with them, agree that continuous miners do not truly mine continuously. In fact, their estimates, and actual studies, show that the real mining time of these machines ranges, on the average, from 20% or less to about 30% of the available shift time.
