Analysis of Roof Fracture Mechanism in Coal Roadway Fault Area and Research on Support Measures
Various accidents may occur during coal mining,and roof accidents are a very common one.Once an accident occurs,it not only affects coal mining and causes economic losses,but also may cause casualties,posing enormous harm.On the basis of elaborating on the main causes of accidents in the roof of fault areas,this study investigates the mechanism of roof fracture in fault areas,and finally summarizes reasonable measures to support the roof fracture of coal tunnels in fault areas.It is hoped that this will be helpful to relevant personnel and the development of the coal mining industry.
