| Abstract: |
| Roadway mine pressure monitoring is one of the important means to ensure the safe and efficient mining of coal mines. However, the traditional monitoring methods have the disadvantages of lack of systematicness, low accuracy, poor reliability, and difficulty in networking. In this paper, the grating sensor is used as a monitoring method to systematically design and develop a roadway mine pressure grating monitoring system including roof separation, bolt stress, surrounding rock stress and bolt load monitoring, so as to solve the shortcomings of current monitoring methods. Firstly, taking the 81303 return airway of Taiping Coal Mine as the research object, the stress distribution law of the two coal pillars is clarified by numerical simulation, and the optimal measuring point layout scheme of the roadway is determined. Secondly, the overall architecture of the roadway mine pressure grating monitoring system is built, and the design and research of the system hardware configuration and monitoring software are carried out to realize the real-time online monitoring and data processing of the roadway mine pressure. In addition, the industrial application test shows that the mine pressure law obtained by the system is basically consistent with the traditional method, and the relative error of the monitoring parameters is up to 1.16 %, which verifies the effectiveness and adaptability of the mine pressure grating monitoring system. |
