It is shown that electrical cable systems used in mining areas experience heavy loads from their own weight, and can also be subjected to mechanical damage as a result of shifting rock layers. This leads emergency situations at enterprises, which threatens the maintenance personnel lives. To compensate for tensile stresses leading wire breakage, extension sleeves various designs are installed on cables. A study was made loading schemes sleeve flat shell elongating elements, showed element...

It is shown that the electricity transmission over long distances accompanied by electrical losses. These energy losses depend on line layout, wires material and their quality, cable fittings service life of system as a whole. The desire to save expensive non-ferrous metals increasing loads power lines led designers idea creating hollow wires. construction length cables limited, therefore, sleeves are used connect them. coupling zone subject electrochemical corrosion, thermal mechanical...

Reducing the level of consumption electrical energy by pressing equipment helps to save resources and, as a result, reduce cost final product. In order exclude large number test passes and not be mistaken with choice equipment, it is necessary have design dependences that make possible determine dimensions blanks used on single-acting presses. An analytical dependence obtained, which makes calculate ultimate thickness blank for drawing without pressing, when no folds are formed. It allows...

Фізико-механічні властивості гірських порід зумовлюють енергетичні витрати процесів руйнування, дроблення і подрібнення.При цьому слід зазначити, що для характерні численні недосконалості дефекти структури, які суттєво впливають на їх міцність при механічній переробці гірничої маси.Одним із основних етапів у технології видобутку корисних копалин є буровибухові роботи, задають інтенсивність рівномірність дроблення, а, отже, ефективність подальших технологічних переробки мінеральної сировини
