Abstract—The complex geological conditions and geomechanical behavior of rock mass at the Tashtagol,
Sheregesh and Kaz deposits induce geodynamic events during transition to deeper level mining. Mining
advance from the higher stress concentration areas in the hanging wall of a fault towards the lower stress
concentration areas contributes to the reduction in rockburst hazard. The use of the self-propelling
equipment provides larger volume of preparatory driving per 1000 t of ore production by 10–20% as
compared with the portable equipment. The mechanism of rock mass movements in deeper level stoping is
revealed. Increased mining depth and high strength of enclosing rocks are favorable for starting extraction
of ore reserves left in pillars. The combination of these factors and the efficient mining system design enable
mining of blind ore bodies without backfill and allows extraction of ore reserves from pillars under the
rivers and ground surface infrastructure.

The area of Gornaya Shoria in the Altai-Sayan folded zone experiences concentrated earth
movements and active seismicity. The iron ore deposits of Kaz, Tashtagol and Sheregesh, which are
under development in this area, occur in complex geological and geomechanical conditions that
govern the choice and design of a geotechnology for the transition to deeper level mining in high
stress rock mass [1–4].
The Kaz iron ore deposit belongs in the Telbes ore cluster in Gornaya Shoria. The ore deposit is
composed of two scarn zones of east–west strike. The site of Central Shtoki, containing the largest
reserves, embraces the northern and southern ore zones represented by series of closely-spaced ore
bodies of east–westward orientation at a depth of 400–700 m. The Lespromkhozny site is a series of
nearly parallel ore bodies of north–east strike at a depth of 350–600 m .
The Tashtagol deposit reserves are proved in the sites of East, South-East and North-West to a
depth of more than 1.5 km, and the Glubokiy site—below 2 km without signs of thinning. The ore
zone in the South-East site is thinned at a depth of 1200 m. The ore bodies in the other sites are blind.
Protodyakonov’s factor of hardness of the ore is 12–14 and often 16.
The Sheregesh deposit lies in the south-west of the Shorskiy Ridge (offspurs of the Kuznetskiy
Alatau) and belongs in the Kondom group of iron ore deposits. The ore zone is 3700 m along the strike
and 150–900 m down dip, and has a thickness of 40 to 300 m. The overall area of the scarn zone is
. The ore sites of the deposit are Glavny, Bolotny, New Sheregesh, Podruslovy and others.
