The working conditions and environment of coal mine shafts are intricate special. Currently, manual inspections or fixed-point monitoring is generally applied for daily safety monitoring, intelligent automated inspection equipment its supporting technologies not available. Starting from the technical requirements electromagnetic adsorption device wall-climbing robot shaft, based on structural c...

LKAB’s Kiruna Mine is located above the Arctic Circle in northern Sweden, and produces about 24 million tons of iron ore per year, making it is the second largest underground mine in the world today. The orebody, a world-class high-grade magnetite deposit, is approximately 4 km long and 80 m wide on average, and lies roughly in the north-south direction, with a dip of some 60 degrees. Surface m...

In this study, a three-dimensional finite difference numerical model of the Jinfeng Gold Mine, including surface topography, ore body, shafts, and main faults, was built to estimate shaft stability deformation induced by underground mining transferred from open-pit mining. Satellite monitoring data displacement at several points used calibrate model. The sequence excavation filling in simulatio...

In the process of coal mining, unreasonable recovery sequence is likely to lead rock subsidence and surface deformation. order ensure safety shaft works as well buildings structures during pillar extend service life mine. this paper, we adopt continuous mining charging method recover protected with engineering background 3 from under dense building (structure) Z mine industrial square. Based on...

In the paper there were discussed factors which determine wear process intensity of shaft hoist rope. The ropes as element or elements set are appearing in numerous, diverse machines and mechanisms, fulfilling most different functions them. Mining hoists a very representative example object being used for vertical transport, both staff mine winning. Results experimental investigations rope pres...

The deepening of a mine shaft is difficult and dangerous operation. Moreover, it requires the continuous operation during process deepening. Because this, necessary to leave plug on bottom or install an artificial bottom. main task provide safety from falling objects for employees working Many solutions platforms have been used in Polish mines over years. A new construction consists using layer...
