Huang yuchuan Coal Mine Fully Mechanized Caving Face Observation and Analysis of Pressure Law

Through the observation and analysis of Huangyuchuan coal mine 216 upper 01 face's mine pressure regularity, it has the accurate records of the whole process about how the stress condition changing for roof support, it shows the pace of first and periodic collapse for immediate roof and main roof, and the stress degree at different position and different time, all of these information provides the evidence for support type choosing and production; and it helps the face roof management.
