Trepanning is a technique used for drilling larger hole diameters where machine power is limited as it is not as powerconsuming as conventional drilling, where the entire hole is converted into chips. The trepanning tool does not machine the whole diameter, only a ring at the periphery. Instead of removing all the material in the form of chips ...

Longwall Miner. Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the seam. The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area.
The coal mining machine is one of the main equipment of comprehensive coal mining equipment. Coal is broken from the coal body through the mining drill bits on the cutting head and loaded into the conveyor. The coal mining machine travels at the adjusted traction speed to synchronize the coal breaking and coal loading process. coal mining machine including continuous miners and longwall ...
The surface mines generate noise from blasting, excavation and transport while the major noise sources from underground mines are the ventilation fan, haulage, conveyor, drilling and blasting and coal cutting machines. The noise is measured on a logarithmic scale and expressed in decibels dB.
Cutters equipped with the CC tips are used to separate coal from the coal seam. Although literature on wear assessment of coal cutting equipment is less in number, the work of Dewangan et al ...

Construction of intelligent coal mine knowledge map. Through the establishment of information entities, the mapping from the physical space to the digital space is realized. This mapping includes not only physical entities (, coal mining machines, hydraulic supports, and tunneling machines), but also time entities (, roof pressure, gas overruns, equipment failures) and functional ...
Longwall shearers cut away the face of a coal seam in longwall mining operations by mounting over an armored face conveyor (AFC). They are equipped with cutting drums positioned against the coal seam by ranging arms powered by hydraulic rams. They can weigh more than 100 tons, travel at speeds up to 30 m/min, and cut away slices of coal seams up to 100 cm thick.

Step 2: Job Task Breakdown. Each job must be broken down into a clearly defined sequence of individual tasks. Avoid defining individual job tasks too narrowly or too broadly; generally speaking, a job should contain no more than 10 individual tasks. Jobs that exceed this number should be separated into two or more separate phases.
Underground mining. Underground or "deep" mining consist mostly of two methods roomandpillar and longwall mining. In roomandpillar, coal deposits are mined by cutting a network of "rooms" into the coal seam and leaving behind "pillars" of coal to support the roof of the mine. The coal is extracted in two phases, first with the ...

Coal mines operated without electricity. Electricity began to be adopted in mining and manufacturing in the late 1880s and the 1890s. (Electricity was first introduced into Ohio's bituminous coal mines in 1889.) The introduction of electricity in coal mines greatly facilitated the introduction of laborsaving machinery. 1891.
