摘要：
According to the results of field measurements and investigations, a mechanical model of sliding caving of jointed immediate roof is established, and controlling indexes of roof caving are studied and analysed in this paper. Because powered supports play a very important role in roof control and support condition monitoring is necessary in coal face the hydraulic system leakage failure detector and new hydraulic pressure information auto-collecting system of powered support have been studied successfully and powered supports have been effectively monitored in fully mechanised coal face.
