摘要
Abstract
The support whether it adapted to the conditions of coal and roof or not, as critical equipment of fully mechanized caving method, has a direct impact to caving efficiency level, so it is necessary to determine its adaptability. Working condition of the support was phased as a result of overburden structure changed in initial stage. Stress analysis of the selected support concluded that the corre- sponding effective measures should be applied to different working condition of the support. Pressure measuring stations were installed at the working face to monitor supporting resistance. The analysis results of all support working condition in initial stage showed that stability and stress state of support was good, and the top coal caving was better, which generally met production requirements.关键词
