Subsurface mining poses risks such as ground collapses, methane explosions, and fires, as well as exposure to toxic substances and gases which can lead to health issues. Additionally, it can impact water sources and cause soil erosion and land subsidence, affecting surrounding ecosystems and communities.
Subsurface mining is generally considered less harmful to the environment compared to surface mining. Subsurface mining causes less land disturbance and produces less waste material on the surface. However, both mining techniques can have environmental impacts if not properly managed.
The difference between surface run-off and subsurface run -off is that surface run-off is that when it is precipitation the water goes on the ground like a river and lake. The water that goes on the top of the ground is going to the oceans. The subsurface run-off is that when it is preciptation the water
i don't know the types of subsurface mining, but i know some facts.surface mining is safer and easier than subsurface mining.You don't have much air underground.It has no or very little advantages compared to surface mining.
The velocity model in seismic imaging is important because it helps determine how seismic waves travel through the subsurface. This impacts the accuracy of subsurface imaging because variations in velocity can distort the images produced, leading to potential errors in interpreting the subsurface geology. A precise velocity model is crucial for accurately mapping underground structures and identifying potential resources.
natural subsurface irrigation :- those areas which lie near to canal and roots zone of crops doenst require irrigation water Artificial irrigation :- by a network of pipe and pump water is provide to the root zone
The roof collapsing Also dangerous gasses
if you work in a mine you can sometimes die

A baseflow is a portion of streamflow which comes from the sum of deep subsurface flow and delayed shallow subsurface flow.

To recover subsurface ores, we use the techniques of underground mining. We sink or extend a shaft to follow the strata that contains the materials we wish to mine and process.
below the earth's surface. Example: the ship can not go in subsurface.

Subsurface flows in the Sun refer to the movement of plasma beneath the visible surface of the Sun. These flows are driven by the convective motion of hot plasma in the outer layers of the Sun, known as the convective zone. Subsurface flows play a crucial role in the transport of energy from the Sun's core to its surface and are studied using helioseismology techniques to understand the dynamics of the solar interior.
