Abstract

Soil pollution due to coal mining and its associative activities has become a serious environmental concern in India. The by-products of coal mining are often disposed directly to the bare lands, significantly altering the characteristics of soil up to a considerable extent. These stacks of discarded rock wastes under the influence of various geological agents, viz., wind, running water, etc., undergo leaching and release trace metals into the soil. Consequently, different environmental, geomorphological, and health problems arise. Various remediation techniques are available for soil pollution, which are classified as conventional techniques like soil replacement, thermal desorption, chemical leaching and fixation, etc. and biological techniques, which are bioremediation and phytoremediation. However, the commercial application of these remediation techniques has not gained popularity due to inefficient technologies, unawareness and costlier methods. Recently application of rock dust has emerged as a potential tool for remediating and remineralising the mine soils along with the management of discarded solid waste rocks. This review details the deteriorating effects of coal mining and allied activities, especially in the case of open cast mining, on the physical, chemical and biological characteristics of soil, discusses the different techniques available for remediation of contaminated soil, and how rock dust can be gainfully applied for soil remediation and remineralisation in India and worldwide. Research gaps and conflicts in the utilisation of rock dust have also been presented.
