Abstract
In order to effectively solve strata pressure control of isolated island face and roadway support difficulty, field observation was carried out in Gubei mine 1232(1) face in Huainan mine area. Through the activity regularity of roof and floor in face and pressure mechanism analysis, the contents and method of the mine strata pressure observation were set up. Based on these works, the rule of strata pressure behavior and first weight and periodical weight step were educed. Finally, the technical advantage and theoretical support are provided reference for high yield, high efficiency, and safety production in other isolated island face which had the similar geological conditions.
