Experimental Study on Failure Mechanism of Soft Rock Roadway in Yangcheng Coal
For the mutual disturbance several roadway excavation, it is difficult to support the roadway and damage is more serious, the original supporting scheme has been out of action, so the article by using the method of field test, theoretical analysis and laboratory experiments on the Yangcheng coal mine soft rock roadway destruction mechanism of in-depth study, based on the theoretical and experimental data measured results were analyzed, and according to the deformation analysis of Yangcheng mine lane, the failure characteristics and causes of roadway, also according to each drill hole core lithology and laboratory test, the basic physical and mechanical parameters, provides a reliable data of Yangcheng coal mine soft rock roadway failure mechanism, for similar geological conditions of coal seam mining also provides practical guidance significance.
