The Ground-Water System and Possible Effects of Underground Coal Mining in the Trail Mountain Area, Central Utah By Gregory C. Lines Abstract The ground-water system was studied in the Trail Mountain area in order to provide hydrologic information needed to assess the hydrologic effects of underground coal mining. Well
In practice, however, there is little or no experience of well dewatering of underground coal mines (except for shaft dewatering) that is available to be drawn upon, and the well dewatering systems that have been published are idealized and not necessarily compatible with field conditions.
Technology Data Sheet Mine Dewatering Groundwater is a common problem when mining, and developing a mine below groundwater level presents many challenges. Poorly controlled groundwater will have negative impacts on the safety, efficiency and economics of mining operations.
The primary objective of mine dewatering is to allow safe and efficient mining to be done Dewatering may impact the groundwater table which is shared with the local communities and environment. This article outlines the important parameters to consider when designing an efficient underground mine dewatering system.
Answering demands for dewatering solutions. 's vertical plate pressure filter (VPA) has been developed to meet increasing demands for higher efficiency and automation in industrial and mining dewatering applications. The new VPA is a heavy-duty machine suitable for metallic minerals, industrial minerals, and coal and tailings.

The most relevant concerns with mine dewatering are related to acid mine drainage and the dispersal of contaminated water into other water fonts and the general environment becoming a serious source of pollution. Types of dewatering techniques and systems. Dewatering open pit mines and underground mines is different.
A flooded mine is one of the direct results of a mine's closure procedure. When a mine stops to operate, its maintenance systems also stop, in which the dewatering systems are included. Without these systems the mine will get flooded by water that naturally sits in rock formations and in the ground.
Pumps & Systems, March 2013 Mining applications are as diverse as construction or water and wastewater applications. Each jobsite has specific requirements and needs. Underground and open pit mines have several layout and design obstacles. Regardless of the mine and its setup, water is a mine's biggest enemy. Getting water out—and keeping it out—is the primary focus of any mine plan. The ...
