The limestone is hard and compact, generally it does not show clear bedding due to its colloidal nature of deposition. It occurs below the overburden of low grade limestone, weathered Red color clay / laterite of 2-5 meters thickness. The soil cover is about 0.50 meter to 1 meter. The depth of limestone varies from 2 meters to 60 meters.

Environmental Effects. Environmental issues can include erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater and surface water by chemicals from mining processes. In some cases, additional forest logging is done in the vicinity of mines to create space for the storage of the created debris and soil.
below the groundwater table. In this case, groundwater must be pumped out of the pit to allow mining to take place. A pit lake usually forms at some point in time after mining stops and the groundwater pumps are turned off.

The process of groundwater replenishment is termed recharge. Groundwater is stored in and moves at varying speeds through aquifers. An aquifer is a water-bearing geologic formation that can store and yield usable amounts of water, and consist of permeable layers of soil, sand, gravel or fractured rock such as granite or limestone.
Mining endangers caves in north-east India. Meghalaya carries a bewitching world in its belly. The natural caves found in Jaintia Hills are a storehouse of geological treasures.

Effects of coal mining in Jharkhand (India) 1. EFFECTS OF COAL MINING IN JHARKHAND 2. Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, vein or (coal) seam. Materials recovered by mining include base metals, precious metals, iron, uranium, coal, diamonds, limestone, oil shale ...
In order to understand the source of groundwater inrush and its hydrogeochemical evolution path truly, determine the evolution characteristics and development trend of water cycle, and effectively solve the problem of water disaster in mining area. In this paper, Jiaozuo mining area, a typical large water mining area of North China type, is selected as the study area.
entific methods. We have carried out an assessment on the environmental effects of limestone quarrying on some com-munities in the Lower Manya Krobo District in the Eastern region of Ghana. Dust emission is one of the major effects of the practice of limestone extraction and as such, dust (PM10) sampling was conducted at the affected communities.
sensitivity of specific ecosystems to mining is examined in Box A2.1. The most obvious impact to biodiversity from mining is the removal of vegetation, which in turn alters the availability of food and shelter for wildlife. At a broader scale, mining may impact biodiversity by changing species composition and structure. For example,
GROUNDWATER CONTAMINATION. 1. GROUNDWATER CONTAMINATION. 2. GROUP MEMBERS NAMITHA M.R. 8 NIDHIN J.K. 9 SAHLA N. 0. 3. POLLUTION vs. CONTAMINATION Pollution signifies any degradation of natural ground water quality while contamination is reserved for pollution that constitutes a hazard to human health. 4.
The mining will force the farmers to revert back to groundwater irrigation further endangering the already dangerous levels of groundwater. Salinity Control "6.25 The age old method for controlling the salinity in coastal areas has been the construction of embankments as a protective measure to stop ingress of sea, water to these lands.

"Ground water quality will be affected with sediments spilling directly into the aquifers. As contaminants in ground water move faster through limestone than other types of rocks, therefore, the effect will be hazardous. Quarrying also removes the entire subcutaneous zone, which is an important ground water storage area," they stated.
Mining activity results in making deep pits which in turn causes ground water table to go down. Contamination of surface water due to dumping of solid waste and dust results in contamination of tanks, rivulets, rivers, open wells and ground water as well. There may be trucks involved in transportation of limestone.
