Abstract

India has reached the forefront of the world coal scene, ranking third in the total coal production, largely due to rapid increase in production from its opencast coal mines. But with a very high density of population, India is in a very disadvantageous position in acquiring large tracts of land for open cast coal mining which involves handling of large volume of waste rock overburden, a portion of which is to be dumped outside the quarry in a convenient place considering the safety, environment and economical aspects. This waste material dumped outside the quarry is termed as external dump. This paper deals with a specific case study of Sonepur-Bazari opencast coal mine, (located in eastern part of India) which has experienced floor heaving near toe of 75metre high external dump standing above 15m thick clay strata fully saturated with water (Fig1). The methodology to tackle the problem of floor heaving by undertaking detailed Slope Stability study and its recommendation is discussed in this paper.

Slope Stability Study of External Dump of Sonepur-Bazari Opencast Coal Mine, India — A Case Study

Arlington, Virginia

India has reached the forefront of the world coal scene, ranking third in the total coal production, largely due to rapid increase in production from its opencast coal mines. But with a very high density of population, India is in a very disadvantageous position in acquiring large tracts of land for open cast coal mining which involves handling of large volume of waste rock overburden, a portion of which is to be dumped outside the quarry in a convenient place considering the safety, environment and economical aspects. This waste material dumped outside the quarry is termed as external dump. This paper deals with a specific case study of Sonepur-Bazari opencast coal mine, (located in eastern part of India) which has experienced floor heaving near toe of 75metre high external dump standing above 15m thick clay strata fully saturated with water (Fig1). The methodology to tackle the problem of floor heaving by undertaking detailed Slope Stability study and its recommendation is discussed in this paper.
