Groundwater impact of open cut coal mine and an

01-09-2017  Open cut coal mining methodologies. The open cut mining method requires the efficient removal of overburden and interburden strata in order to access coal seams. An open cut pit is normally commenced through excavation of a box cut or initial slot into an area where the pit basal seam subcrops and the stripping ratio is low.

2.3.5.3.1 Coal seam gas operations and open-cut

Open-cut coal mines can have a localised effect on preferential flow paths in surrounding aquifers, affecting surface water – groundwater interactions. This includes changes to hydraulic gradients in the alluvial aquifer and connected aquifers associated with mine pit dewatering and preferential drainage and recharge associated with post-closure water filling the pit.

Open-pit Mining, Opencast Mining, Open-cut

The excavation of the coal starts by first removing the overburden and then recovering the coal seams. Excavation helps to understand the depth of the mountain. In the nineteenth and early twentieth century the coal mines were not that deep. Almost everywhere there were surface mines .Surface coal mining in the early twentieth century included contour mining, which removed the top layer of soil to get a coal seam.

Surface mining - Wikipedia

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels. Surface mining began in the mid-16th century and is practiced throughout the world, although the majority of surface coal mining

Blasting Techniques Used in Underground and

Blasting out coal in the centre of the face in the wedge cut pattern gives free face for the remaining coal. The maximum permissible charge to be used per hole therefore varies-when blasting out the central wedge with P5 explosives and when blasting out the remaining cola (after the central wedge is blasted out thereby providing free face) with P1/P3 explosives if these are used.

Ingleton Coal - Northern Mine Research Society

As a result, the thickness of coal bearing strata varies considerably and in places the coal seams have been removed altogether. Mining was, therefore, confined to the southern part of the coalfield, where the seams dip northwards at 1 in 4, but in places are even steeper. There are several coals, but not all of them were worked, because they ...

In room and pillar mining, pillar extraction can be so designed that mined out area is submerged in water.This provides excellent inertization but is possible only in highly inclined coal seams. Most commonly, self-inertization is provided by the methane gas released from coal seams in the gas emission space.
