Safety performance of coal mine survey technology using nano-fiber material in coal mining process

Abstract

In order to ensure the safety of coal mining process, in this study, the coal mine survey technology based on nano-fibers is analyzed and Marston-Spangler theory is used to calculate the vertical earth pressure, and then evaluate the safety of coal mining process. The research results show that the whole process of coal mining by using advanced nano-fiber material technology is discussed, including geological survey, mine development and layout, establishment of related facilities, and coal mining and transportation systems. It is better to evaluate the safety performance of the whole process by the earth pressure and the internal force of the structure. The larger the slope angle is, the greater the vertical earth pressure and the cross-section internal force are. The internal water pressure has little influence on the lateral bending moment of the structure, thus increasing the circumferential tension. It can be seen that the research on the safety performance of coal mining process based on nano-fiber materials is helpful to find out the unsafe factors of coal mining process, and then to evaluate the safety performance, which is of great significance for coal mining enterprises to obtain economic benefits.
