In open cast mine projects, Slope stability of overburden dumps plays an important role. Flyash released from the coal based thermal power plants is increasing day by day. This should be disposed properly such that it does not cause any harm to the environment. So in the present study the flyash is used as anadmixture for the improvement of slopes by utilizing itin proper way making it environmental friendly. The stability investigation of overburden dump for various rates of flyash has been finished utilizing GEOSTUDIO software and concluded that among all the Limit Equilibrium methods, Morgenstern price method gives best results Various tests are performed on soil to find parameters like cohesion, angle of internal friction, density which are the inputs to GEOSTUDIO software, to find slope stability.
