Experience in Application of XLPD Extra Low-Profile Robotic LHD for Narrow Bedded Vein Mining at Mine No.8 of 'PIMCU' PJSC named after E.P. Slavsky
The paper presents the demonstration test results of the XLPD trackmounted low-profile LHD designed by DOK-ING for narrow bedded vein mining (m=1.6-1.8 m). These tests were performed in Mine No.8 of 'PIMCU' PJSC. The demonstration results proved the applicability of this equipment for the conditions of Mine No.8 due to reduced dilution, improved safety of mining operations, decreased volumes of both mined and processed ore keeping the metal production at the same level. The main economic effect of utilizing this complex can be obtained by cutting the metallurgical conversion costs.
Global Oil and Gas Market: basic trends
After several years of crunch , the oil and gas industry demonstrates signs of revival given the ramping up of U.S. oil and gas production and the sense of optimism that is sweeping the sector. In general, the industry feels much healthier than it did 12 months ago: the price of oil has rebounded. After appearing limited to a range between the mid-$40s and $50 per barrel, Brent crude is now trading above $60. The industry is thus recovering from the brutal last few years of weak prices. The fundamental challenge, of course, is the intrinsic volatility in the sector facing serious problems.
Management of Complex Stability Monitoring of External Dumps Made up of Soils with Low Bearing Capacity and Located on Weak Base for Conditions of PJSC «Mikhailovsky GOK»
External dumps of PJSC «Mikhailovsky GOK» were formed on a weak watered base which presents the least favourable conditions to ensure their stability. Refuse rock was dumped in the controlled deformation mode. This method can be applied if enough free land is available and the mining equipment makes it possible to locate the dump outside the deformation zone. However, at the present time it does not seem possible to dump the refuse material in this way.
A Concept of Development Strategy for Gold Deposits in Southern Urals through Application of Innovative Geotechnologies
Specific features of the Urals gold deposits at the mature stage of their development are considered in the paper. It presents principal provisions of a long-term project for time-phased implementation of lean operations at the ‘Noviy Kochkar’ Mining and Concentration Complex. A new concept of the strategy to develop gold deposit in the Southern Urals is based on unleashing the resource base potential through application of innovative geotechnologies and securing sustainable development of the company in the present-day context.
