The paper deals with the geotechnical study and slope stability of the dragline highwall slope at Lajkura open cast coal mine, Orissa state, India (Fig. 1). At the mine, 22m of overburden immediately above the Lajkura coal seam (having a thickness of 18 m) is being removed by deploying a 10/70 dragline machine. Initially benches are being left in the coal seam.
Therefore, this study aims to develop and apply artificial intelligence in predicting blast - induced ground vibration in open - pit mines. Indeed, the k - nearest neighbors (KNN) algorithm was taken into account and developed for predicting blast - induced ground vibration at the Deo Nai open - pit coal mine (Vietnam) as a case study.
Quarry Specific Lasers. Lasers exist which have been specifically designed for quarry or mining use. The MDL Quarryman is a good example of such lasers. Its a very easy laser to setup, very rugged, easy to survey with, and easy to process its data.

3 The narrow economic base of many coal mining regions requires careful mitiga-tion of coal mine closure impacts. Coal mining is often concentrated in regions far from major population and economic centers where alternative employment pros-pects may be found . As a result, mono-industry coal towns and regions face mul-
tation are 2 to 150 Hz for coal mine and quarry blasting, and 5 to 200 Hz for construction and excavation blasting. When higher or lower frequency vibra tions are possible, as in construction blasting or for a quarry shot close to a residence, care should be taken to insure proper choices of instrumentation and vibration criteria.
