In case of long tunnels at greater depths (in mountainous areas) the investigation possibilities are rather limited due to high cost. In such areas the investigation is mainly based on classical hydrogeological studies, procedures and techniques and covers a broader area for getting all necessary data and all geological boundary conditions.
Data obtained during a hydrologic study of the Price River basin, Utah, are used to describe seasonal variations off low of springs, relation between ground water and surface water, hydraulic properties of the groundwater reservoir, groundwater recharge and discharge, flood characteristics of streams, mineralogic composition and depositional rates of sediments, nutrient and inorganic loading ...

Estonia and have long term hydrological and mining records available (dating back to 1923). These rivers have been subjected to intense human impact, mainly due to mining operations since the beginning of 20th century [14, 15]. In comparison, the River Keila is located approximately 150 km west of the oil shale mining area.
water supplies (Lehr, 1969); whereas in the Carlsbad potash area, the groundwater quality before the presence of the potash industry was questionable because of abundant natural salt deposits near the surface. The BLM recognized that a complete hydrologic study of the Carlsbad potash area would be timeconsuming and expensive. To better

Since large icefree continental areas are underlain by karst (, 35% of Europe) and they are in many places around the world crucial for drinking water supply (Ford and Williams, 2007, Hartmann et al., 2014), additional evaluation of different hydrological models in such areas is even more important (Goyal et al., 2017). In the case of ...
The goal of the Division of Mine Permits is to protect human health and the environment from adverse effects of coal mining and reclamation operations. This is accomplished by evaluating mining and reclamation plans and issuing permits to ensure that coal mining operations meet the performance standards established under the federal Surface ...
"Hydro" comes from the Greek word for... water. Hydrology is the study of water and hydrologists are scientists who study water. Read on to learn more. Water is one of our most precious natural resources. Without it, there would be no life on earth. Hydrology has evolved as a science in response to ...
areas of West Bengal (News items in local news papers). Ground Water Condition at Some Indian Mines Very often, in India, a mine planner or a mining engineer faces ground water seepage problem either in a running mine or in opening a mine (whether open pit or underground) which calls for a through indepth hydrogeological study of the ...
FOUNDATION DESIGN AND CONSTRUCTION PRACTICE IN LIMESTONE AREA IN MALAYSIA Tan1 Chow2 Abstract: The design and construction of foundations in limestone areas have posed various problems to geotechnical engineers due to the karstic features of limestone such as steeply inclined bedrock, cavities, floaters, etc.
The recharge source for karst water deep in a mining area is water from higher mountain areas, which is transported via vertical leakage [9]. Surface and subsurface karren, grike, and dissolution pores in karst mountainous areas are abundant [10], causing the runo coe cient of the slope surface to be lower than that in nonkarst areas [11–13].
inventory found 165 active operations, 88% of which were limestone quarries (Nelson and others, 1990). That same inventory counted 1,367 inactive operations, 70% of which were limestone quarries. Aggregate mining is an extractive use of resources: mining alters the landscape and its natural hydrologic system.
The Idrijca River is 60 km long, and it drains the former Hg mining area of Idrija, Slovenia . It is a karst area with highlying karst plateaus up to ∼1100 m high that descend steeply towards a narrow valley. Deeply karstified limestone exists there with alternations of massive dolomites and conglomerates in .
The study of [4] led to subdivide the upper Dja series in four lithological units from bottom to top, there are: The unity of Kol, made with diamictite on its base and pelit on the summit; Metou unit composed of massive dolomite; Mominbolé unit that has an alternation of limestone and clay: it is a pelitic limestone and the Atog Adjap unit composed of clear limestone and yellowish gray band.

The paper describes a case study carried out for evaluation, planning and management of water resource in and around a limestone mining area located in Bamangaon and Mehgaon village of ...
Because karst features evolve in response to specific hydrologic conditions that have changed significantly over geologic time, many karst features are in areas where they could not form readily today. Florida''s coastal springs originally formed as sinkholes in a recharge area where acidic waters were undersaturated with respect to calcite.
to study every critical aspect including the hydrological and hydrogeological studies but especially aquifers, so that mining activities can be well managed and the impact on the environment can be overcome. The study of the aquifer from the study area was based on .
The study revealed that open cast mining of limestone rock''s and direct contact of wastewater from the cement plants into the water bodies does have a negative impact on the physicochemical characteristics of the waters of the area. Thereby, indicating a serious problem on availability of clean water in the area.
Thickness of aquifer is also to be considered when find about the other parameters. Geological and hydrological studies of aquifer in the Kuteshwar limestone deposit area found that aquifer thickness varies enormously and variation contributes significantly to the spatial variability of aquifer parameters.(B. Venkatanarayana, et al,1999)
