In geology, a massif ( /mæˈsiːf/ or /ˈmæsɪf/) is a section of a planet's crust that is demarcated by faults or flexures. In the movement of the crust, a massif tends to retain its internal structure while being displaced as a whole. The term also refers to a group of mountains formed by such a structure.
Method of driving a mine working in massif subject to tectonic stresses
FIELD: underground mining in rocks.SUBSTANCE: method of mining a working in a rock mass exposed to tectonic stresses includes making a straight cut with the formation of a cutting cavity in the centre of the mine working, determining the direction of the greatest compressive stress in the massif and forming the mine working. If the greatest compressive stress is found in the horizontal transverse direction to the contour of the working, the cutting cavity is expanded by exploding pre-contour and contour blasthole charges in the horizontal transverse direction to the contour of the mine working, whereas as a result of the explosion, a dome-shaped part of the cavity of the mine working is formed due to the natural destruction of the rock.EFFECT: increase in the stability of the workings' boundary rocks.1 cl, 3 dwg
