• Analysis of the maintenance of the powered support capacity of the longwall support based on the actual tests
    The article presents an analysis of the operation of hydraulic props of a mechanized longwall support based on actual tests. The research shows that in the sections of the support, there may be large differences in the pressure values ​​in the plunger space of the props, and the sections may be stretched to different values ​​of the initial load capacity and work with different working loads. Moreover, pressure drops in the props were observed immediately after completion of the expansion cycle. The above may result in uneven support of the ceiling along the wall, which affects the improper cooperation of the casing with the rock mass, and as a consequence may cause difficulties in exploitation. Based on the research, it was found that the value of the pressure to which the section is spread directly depends on the instantaneous value of the pressure in the supply line, which varies in time. Its falls may cause difficulties in the expansion of the sections and, consequently, the casing may not obtain the required initial load bearing capacity. Therefore, it is important to control the operating parameters of the housing during operation. Obtaining the required initial and working load capacity by the cladding is of great importance for the stability of the floor. Therefore, it is justified to monitor the operating parameters of the section, and in particular to use pressure monitoring in the powered supports.
