Some open pit mines may have the potential to form a pit lake either during or after the mining operation ceases. During the operating life of a mine, any groundwater encountered is generally pumped from the mine creating a hydrologic capture zone or groundwater sink.
Open pit mining results in huge quantities of waste rock. First, to reach the underground ore deposit huge quantities of rock must be removed. This rock, called overburden, is dumped as waste. Secondly, the copper ore itself is very low grade. The copper ore in Intag has a copper concentration of % 1. This %, along with % molybdenum ...

Openpit mines are typically enlarged until either the coal is exhausted, or an increasing ratio of overburden makes further mining uneconomic. When this occurs, the exhausted mines are sometimes converted to landfills for disposal of solid wastes. However, some form of water control is usually required to keep the mine pit from becoming a lake.
SURFACE MINING ≠ STRIP MINING: Although sometimes mistakenly referred to as strip mining, oil sands is actually mined from an openpit below several meters of mining is the mining of a relatively flat deposit very close to the surface, commonly used in coal or phosphate industries.
May 22, 2014· Mine dewatering techniques. Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a prerequisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts. However, techniques are available to successful control groundwater.
