| Sumario: | In modern conditions, intensive underground coal mining is provided, as a rule by working out the dredging sections of coal seams with long cleaning faces using high-performance mechanized complexes. They consist of a dredging machine, a conveyor and a set of sections of mobile mechanized support (SMS). SMS, supporting the roof, controlling the mountain pressure (MP) and protecting the bottom-hole space, provide conditions in complex mechanized treatment faces (CMTF) for efficient and safe coal mining. However, the potential capabilities of modern complexes significantly exceed the values of efficiency indicators achieved when using them in operating conditions. One of the reasons for this situation is the insufficient adaptability of the SMS to the mining and geological conditions (MGC) changing in a wide range as the excavation sites are worked out. Therefore, at present, studies of the possibility of developing the properties of adaptivity (kinematic, power, contact, technological) of the SMS to the MGC variables are relevant. Their results will contribute to the expansion of the functional capabilities of the SMS to maintain favorable conditions in complex mechanized treatment faces for the effective operation of the mechanized treatment complex (MTC) in variable mining and geological conditions. |
