Studying mathematical model of mine and quarry pneumatic lifting equipment in "skip - guidance devices" systems

There are two basic ways of mining: open pit and underground in the mining industry: open pit and underground. Underground mining less profitable, however, it is more environmentally friendly. In addition, this method is essentially inevitable due to the fact that the major mineral reserves are at greater depths and in the future will need to solve the problems of development of mineral deposits deep mines. The development of the mining sector and the deepening of mining operations require a new type of transport, justified and developed in the works of Bogatyrev M. D., Kiselev V. I., Kartaviy N. G., Saginov A. S., Nechyporenko S. N., Piskunov O. M., Nikolaev Yu. A. - skip pneumatic lifting equipment designed to reduce the cost of transportation of the rock mass

Using of science technologies for mining machinery constructions' strength improvement

Recommendations for strengthening the brake construction in accident dangerous areas of fatigue destruction were developed. Computer modeling was made using the ANSYS program that helps to visualize stained condition of the construction for further practical testing of the strength and reliability improving technology of mining elevating machines' constructions, which are being in a long-term use, with a help of the strengthening elements. A way of construction strengthening, which eliminates the possibility of further fatigue destruction of the brake system elements, because of the load cycle in exploitation process
