Forum leader Angela Rangad said Sunday there were 24,626 coal mines in the district about 52 mines/sq km at different stages of mining. The forum alleged collusion between the state government and the illegal coal miners wherein the courts and the NGT were misled on several occasions on the total amount of extracted coal waiting to be transported.
an important tool for mapping internal structures of pegmatites and thus assisting future mining activities.

Ground penetrating radar – radar used to scan images of what lies beneath the surface. Hanging wall – the area above where the ore is present in a mine. Hydrometallurgy – a method of extracting minerals/metals from ore using waterbased liquids.
Ground Penetrating Radar. Whether it's a standard excavation or new service installation, a geophysical map for the purposes of engineering, an environmental assessment or a search for potential burial site, we are there.
The factor most affected by coal mining was GWT, which dropped from a depth of m before mining to a depth of m after mining at the Bulianta Coal Mine based on water well measurements. Groundpenetrating radar at frequencies of 25 and 50 MHz revealed that the deepest GWT was at about m.

A current challenge with automating underground coal mining machinery is measuring and maintaining a coal mining horizon. 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.
