  • Fully mechanized coal mining technology for thin coal seam

    The extraction of thin coal seams will liberate the hold-up coal reserves, increase recovery rate of coal resource and extend the mine lives. With the implementation of the fully mechanized thin coal seam mining technology in highly gassy mines, it can speed up the mining of methane releasing coal seams, achieve a balanced extraction

  • Mining technology

    - Layer mining of the 3rd seam At present time about 70% of ore is mined using longwall mining technique (faces 180-300 m long). 3. Combined system of mining The 3rd potash level has three productive sylvinite layers (II, III and IV) divided by seams of halite. When using the combined system of mining, the upper (IV) sylvinite layer is mined using the pillar technique and the subjacent layers

  • Coal seam Energy Education

    A coal seam is a dark brown or black banded deposit of coal that is visible within layers of rock. These seams are located underground and can be mined using either deep mining or strip mining techniques depending on their proximity to the surface. These seams undergo normal coal formation and serve as a conventional coal resource.The reserves of coal are immense, and are the largest of all of

    Pramod Thakur, in Coal Bed Methane, 2014. 8.1.2 Reservoir Properties of Coal Seams. Coal seam degasification techniques to be used in a mine depend on the reservoir properties of the coal seams being mined. Good methane control planning depends on accurate information on the reservoir properties of the coal seam and the total gas emission space created by the mining process.

    It has been mining for 37 years. The shape of the coal seam in this mine is like "M". Two anticlines are intersected by one syncline. And the deeper the mining, the greater the dip angle of the coal seam. As mining time goes by, coal reserves of 50° and below become less and less, and an average inclination of 60° and above will become the normal. There is no precedent for China to implement mechanized comprehensive mining

The multi-seam design will focus on the No. 2 and No. 4 seams as these are the seams that are currently being mined by underground methods at Khutala Colliery. The seam thicknesses and the parting thickness between the seams

The chapter discusses: three surface mining techniques that are used in the West: 1) area strip, 2) open pit, and 3) terrace pit; two methods of underground mining in the West: 1) room and pillar with contin-uous miners, and 2) longwall mining; recent underground mining technology

Then all the criteria affecting the mining method and the relations between them are defined by experts of the system. Finally AHP is used to find the method with the highest performance according to the selection criteria defined. Within

This is often called “content-aware” cropping or image retargeting. Its an algorithm that lets you go from this: Photo by Pietro De Grandi on Unsplash to this: As you can see, most of the important content in the image: the boats,
