Substantive inflows to underground workings are usually associated with the intersection of discrete fault zones of high transmissivity. If those fault zones are in hydraulic communication with a surface water body, or intersect a near-surface aquifer of high hydraulic conductivity, substantial inflows can be expected.

The typical mining technique involves driving heavy machines underground, breaking up the rocks, and throwing them into a vat or tank below ground. However, with today's modern equipment and techniques, the entire operation can be conducted above ground. Today, there are many techniques that have been developed that make this easier and safer.

Working safety in underground mining is related to blast operations, rock conditions and mining methods. The potential for roof problems, rock spalling, rock bursts, rock falls and brow damage is rife. It is a common problem that rock blasting in underground mines makes local underground water contaminated. The problem stems from two reasons.
