摘要：Due to increasing efforts on saving natural environment – observed also as an increase ofrenewable resource energy production – a traditional underground coal mining introduces newtechnologies of machine diagnosis to assure this process to be more safe and generate lesspollution. Also the economic reasons influence development of monitoring systems. Among themost important elements of underground coal mining are longwall systems, whose essentialparts are powered roof supports. Avoiding failures and limitation of power consumption shouldresult in more ecological underground coal mining. The paper presents the new model ofpowered roof support single unit work. The better understanding of its operating and thepossibility to generate data describing a proper and improper operation will help to developmonitoring and diagnosis systems.
