The characteristic o f modern landscapes o f the Kerch Peninsula as geologic systems in which natural and economic subsystems are inseparably connected is presented in the article. The component structure o f the landscapes o f the Kerch Peninsula (geological structure, relief, climate, water, soil, flora and fauna) was analysed using constructed thematic maps. The complex structure o f the landscapes o f the Peninsula is presented, with the indication o f landscape levels, landscape zones, landscape areas. The description o f the modern economy o f the Kerch Peninsula as an economic subsystem has been completed. The modern landscapes o f the Peninsula show varying degrees o f integration o f natural and economic components. This can be shown by overlaying the maps o f the natural and economic subsystems. The maps o f the natural and economic subsystems, and o f the modem landscapes o f the Kerch Peninsula, are provided in the work. It is shown that the map o f modern landscapes can be used in territorial planning, including landscape planning. This cartographic model can be used as a basis for integrated assessments o f territorial differences and evaluation maps.
Shafts in Gubkin Mine, KMAruda have been in operation since the late 1940s. The shafts are sunk in difficult hydrogeological conditions. At the present time, due to transition to deeper levels, deeper mine dumps are required. It is necessary to reinforce shaft lining in watered rocks. During long-term service of shaft 1, due to corrosion, thickness of liner plates and horizontal ribs has decreased by 1.5–2 and 3–5 mm, respectively (two-side corrosion). As a result, the load-bearing capacity of the tubbing has lowered by 5–7%. At the same time, the actual stresses are not higher than 22 MPa, which is 10 times less than the design compression resistance of gray cast iron as per Construction Code SP 16.13330.2017. Field studies have been performed in Gubkin Mine toward improvement of operating safety of shafts during mineral mining at deeper levels. Stress state diagnostics of lining in shaft 1 shows that the lining preserves its load-bearing capacity in all types of rocks. Thus, safe operation can be continued without extra expenses connected with the lining reinforcement. The field studies in the cage shaft show that pressure on the lining in frozen rocks is 1.5–2 times higher than the design values. It is recommended to continue the studies to estimate effects of possible rock displacements on the lining during further mining.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
