Of fly ash is found stable with a safety factor of 1.78 for the above geometry. Therefore, the above geometry of the back filling material was recommended fo...Fly Ash Mixing with Mine Ob Dumps: An Enviro-Friendly, Clean and Green Method of DisposalMATTER: International Journal of Science and Technology, 2017Fly ash generation, its utilization and safe disposal is a major problem faced by thermal power plants (TPP) in India. Despite several efforts of the government, the utilization of fly ash is reached to only 55% of the total fly ash generated and remaining 45% fly ash is still being dumped into poorly designed and maintained ash ponds. At present, fly ash is mainly being utilized for making cement, bricks, concrete, roads and small quantity in mine void filling. The consumption of fly ash in construction activity has reached to almost saturation level and there is not much potential to consume more fly ash in these segments. Mine void filling is the only potential area where bulk quantity of fly ash can be utilized and 100% utilization target can be achieved. This paper investigates the suitability of fly ash to be disposed off by mixing it with overburden (OB) dumps in coal mines. Characterization of both the OB dump material and fly ash were carried out in the laboratory. The compaction and shear tests were performed on OB dump material and the same mixed with 25% fly ash by volume as per the guidelines issued by Ministry of Environment Forest and Climate Change, Govt. of India. The stability condition ofGEO-ENGINEERING PROPERTIES OF FLY ASHThe aim of the Project is to find out the geo-engineering properties of fly ash, in geo-engineering field. The project describes the use of local fly ash in construction industry in a way to minimize the industrial waste such as fly-ash, slag etc can be effectively used in soil stabilization. If these materials can be used in highway or dam construction, it will be a great effort in minimizing the industrial pollution. Experiments are done in order to determine the geo-engineering properties of fly ash, which can taken account in the construction field. A brief comparison is made between fly ash and other soil properties which are used as sub-grade, base in Highway construction.Geo-hydrological Stability Analysis of Fly Ash Stabilised Overburden Dump Slopes in Opencast Coal Mines Using Finite Element AnalysisInternational Journal on Advanced Science, Engineering and Information TechnologyFly
