10-11-2016 Access hole N+2 has a region in deck 3 which is hypothesized to be sub-economic, so the exemplary method can focus nozzle induced disaggregation in this area and production ore can be analyzed on surface to confirm if the region is economic or not to mine and if mining can continue.
Borehole Mining (BHM) is a remote operated method of extraction of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jets (hydraulicking).This process can be carried-out from land surface, open pit floor, underground mine or floating platform or vessel through pre-drilled boreholes.

Borehole Mining No longer a science project, borehole mining is proving itself as a workable technology that can be applied to a number of industries. Hydraulically jet-cutting a cavern of rock 20 feet in diameter from a drilled bore hole allows this system to recover resources previously uneconomical for open pit or underground mining operations.

To determine whether 130 felt earth tremors around Edwinstowe, Nottinghamshire, UK, which also experienced severe surface fissuring, were caused by coal extraction, a surface seismometer array was established around Thoresby Colliery. Over the next year, 785 microseismic events were detected. The spatial and temporal variations in seismicity are clearly associated with the commencement ...
Unlike an adit, a drift need not break out to the surface. Drift mining is the use of drifts to extract ore - in this case the drifts follow the vein. A "level" is a horizontal passage that branches off from a shaft and is used for access to the parts of the mine where the ore is being removed.

In terms of method of extracting mineral from deposit, mining can be classified into: surface, underground, and borehole mining. Surface mining is a form of mining, in which the soil and the rock covering the mineral deposits are removed. Types of surface mining include mainly strip and open-cast methods, as well as quarrying.
protections for your surface and water rights. You should negotiate a surface use or damage agreement that protects your surface interests in conjunction with a mineral lease or the mineral lease should require negotiations of a surface use agreement before any drilling takes place.
PANELS THROUGH A SURFACE BOREHOLE In this instance, the borehole was drilled before mining into the center of a panel so as to drain methane from the gob after the panel was retreat mined. The coal mine is located in Monongalia County, We Va., and the study area consisted of panels 5-9, right off 3 North Mains (fig. 1).

Borehole mining consists of two pipes one for pumping down high pressure water and another that delivers slurry back to the surface. A BHM tool consists of water jet pump, hydro monitor section, an extension section and a hub. The tool is lowered into a well until the hydro monitor reaches the depth of the hole where the borehole mining is started.

Due to different deflection angles of adjacent strata, the horizontal movement of strata varies, and this contributes primarily to the dislocation of borehole wall. As the development of strata movement from the mining level towards surface, the position of borehole dislocation also occurred upwards, and the highest borehole dislocation occurred at the same position of overlying Key Stratum (KS).
