Mine Groundwater Drawdown: Thiem Cone of Depression (2D)

This 2D companion drives the same mine-dewatering hydrogeology as the 3D version through a plain cross-section view built for reading the maths: a side panel exposes the pumping rate, aquifer transmissivity and radius of influence, the canvas renders the pit excavation sitting inside a real Thiem-equation cone of depression, and a draggable observation distance shows exactly how far the water table is pulled down at any point around the pit — while a live readout confirms, via mass conservation, that the water flowing into the pit equals the pumped rate.
