Research on surrounding rock control technology of deep roadway based on butterfly failure theory
Meitan kexue jishu, 2023 At present, roadway surrounding rock control is still one of the major problems in deep mining of coal resources. The formation and development of the plastic zone of the surrounding rock is the main cause of large deformation and failure of roadway.

Numerical simulation study on support design of deep roadway
IOP Conference Series: Earth and Environmental Science, 2020 Abstract In order to solve the problem of large deformation in deep roadway mining, the stress and deformation of surrounding rock after roadway excavation and support are studied by numerical simulation. The results show that the displacement of roof and two sides is large after the roadwayexcavation.

Rock burst criteria and control based on an abutment‐stress‐transfer model in deep coal roadways
Energy Science & Engineering, 2020 With the increase in cover depth of the coal seam, more and more rock bursts have occurred in deep coal roadways. The conventionally used passive preventive measures are not sufficient to reduce rock burst hazards in deep coal mines.

A comparison of deep learning algorithms on image data for detecting floodwater on roadways
Computer Science and Information Systems, 2022 Object detection and segmentation algorithms evolved significantly in the last decade. Simultaneous object detection and segmentation paved the way for real-time applications such as autonomous driving. Detection and segmentation of (partially) flooded roadways are essential inputs for vehicle routing and traffic management systems. This paper proposes
