Abstract: Effective mining horizon sensing is an issue of major importance in the coal mining industry because it directly impacts the productivity and safety of the resource recovery process. However the development of automated mining horizon control capability has been significantly hindered by a fundamental lack of sensing that can reliably measure the coal-strata geological structure in ...

The factor most affected by coal mining was GWT, which dropped from a depth of 35.41 m before mining to a depth of 43.38 m after mining at the Bulianta Coal Mine based on water well measurements. Ground-penetrating radar at frequencies of 25 and 50 MHz revealed that the deepest GWT was at about 43.4 m.

Robust thin layer coal thickness estimation using .

The coal mining horizon is the horizontal path the machinery follows through the undulating coal seam during the mining operation. A typical mining practice is to leave a thin remnant of coal unmined in order to maintain geological stability of the cutting face. If the remnant layer is too thick, resources are wasted as the unmined coal is ...

Dependable fill-level control in coal mining

The aquifers surrounding the coal mine become drained, which leads to a sinking of the depression cone. This sinking alters the natural hydrological conditions underground by creating paths of lowered resistance. What this then leads to is water penetrating the open pit and underground workings.
