Trepça mine in Stantërg during its activities of exploitation periods divides this process in three stages of exploitati on, where in the first stage there are old exploitations of levels from 830m and 610m, and the way of exploitation method, dimensions of backbones and securing plates has been change d as a result of determination of height of floor-horizons between them. The heights of 30m and the angle of small fall allows this method of exploitation to be more favourable and secure. Securing backbones, are ...

Mining bodies that lay in the depth of Earth’ s core always appear as irregular bodies in different geological- mining circumstances. Mine “Trepça” in Stanterg since the beginning of its work in 1930 up to now has applied several exploitation methods of mining bodies, and one of these methods is the so called Frontal Method. This method is applied in cases when the ore body has small sizes in length from 30m and the fall angle up to 30º. During the app lication of this method, the securing backbones have b...
