Abstract


With the increasing mining depth , ground pressure appearing more and more prominent , has become one of the technical difficulties of the problem in China's coal production . To Deep Mine High stress as a starting point , analyzed on the basis of in-depth exploration and understanding of Deep Roadway deformation failure mechanism and stability of the evolution of Deep Roadway stability control theory ( rock stress recovery - Wai rock status enhancement - part of the consolidation and repair - stress transfer load ring to expand ) deep Roadway stability Control technology countermeasures . According to the coal mines of Deep Roadway grading system , a pilot study by Xiaoyi City of Shanxi Xing Yue coal mine roadway surrounding rock and the physical and mechanical parameters derived the mine test Roadway generally belong to the class III Medium in stable rock , initially set the basic parameters of this type of rock bolting . On the basis of theoretical studies , comparative analysis simulation program that Deep Mine High pressure roadway need to control not only the roof and floor , also need to be strengthened to help control and come to class deep roadway support . Xing Yue South of coal mining area Shimen double - track section of roadway in the of Deep Roadway stability control theory under the guidance of the support construction of the supporting effect of the dynamic monitoring , draw of the support program to control deep Roadway deformation, so that the support theory with good results in the field of deep wells roadway has important theoretical and practical significance .
